How To Make Subwoofers Louder

How To Make Subwoofers Louder: 10 Effective Ways

Bass waves produced by subwoofers are known for their high frequencies and rich bass. Despite their improved sound output, it may still be necessary to use an amplifier. In addition to increasing the volume and depth of a sound, amplifying it also ensures that it is heard the same way throughout a room or arena.

Sound distortions are prevented and improved by amplifiers because they increase bass output. In addition to being expensive, amplifiers require constant maintenance. You can find alternative ways to power your subwoofer if you are not willing to spend much money on it.

Using different techniques, you can easily amplify. Here are some options for amplifying the subwoofer box’s output:

How to Make Subwoofers Louder Without an Amplifier

Before making the subwoofer louder we need to know how the subwoofer works in our blog post.

1. Place your subwoofers correctly

Subwoofers can be easily increased in noise output by positioning them differently. Adjusting the woofer as per the recommended position may be necessary to experience the best sound. There is a tendency to place subwoofers in the corner of the home. There are, however, some cases where that may not be ideal. It is possible to get the best bass sound output by placing the subwoofer in the corner of the room. It is important to note that not every person will receive the same level of bass output because of placement.

The sounds may be less audible for some people. Nevertheless, corner placements provide the most bass output without an amplifier without adding an amplifier. Place it in the center of the room to ensure everyone hears equal bass output. The bass response is evened out by placing the speakers in such a way, creating a consistent sound throughout the room.

When placing the woofer in a small house, make sure there is at least an inch of space between the woofer and the wall. Subwoofers with rear ports are recommended to be placed in this position. The loudest possible bass output will be achieved even in rooms with worm shapes that aren’t rectangles or squares. Try to position the subs asymmetrically if the worm is anything other than rectangles or squares.

The subwoofer can be placed behind the couch if there is a space crunch, but never under it. A dampening effect will be achieved by placing it under the couch.

2. Tune the subwoofer properly

An amplified bass effect can also be achieved by tuning the subwoofers. The “Boom effect” is a signature feature of subwoofers, but tuning the woofer is needed to achieve louder and clearer audio. Depending on the woofer’s controls, you may need to adjust them to ensure the machine does not strain too much.

3. Adjust phase & crossover settings

In addition to crossover settings, phase settings are also essential for subwoofers. During the sound system’s installation, ensuring that the woofer is in phase with the other components is important. You can use the single-phase switch or balanced meals to adjust the settings to ensure that the phasing is properly set. The crossovers typically come with a dial ranging from 0 to 180 degrees.

Once you get the desired sound output, adjust the settings and phasing. Observe the crossover settings closely as well. A speaker that does not have a correct crossover between the main and lower speakers will not produce precise sound and will be unclear if the crossovers are not optimized. There is a risk that speakers will cancel each other out due to an incorrect crossover level. In turn, this results in a distorted sound and a shabby voice, which in turn results in a distorted sound.

A speaker’s size determines the ideal crossover frequency. Higher frequencies are better suited for smaller and more compact woofers than lower frequencies for larger speakers.

The adjustment can be enhanced by playing heavy bass music.

For the optimal sound and the deep bass subwoofer, we have two options for you Polk Audio PSW108 Vs Polk Audio PSW10.

4. Files Must Be Use High-Quality 

High-quality subwoofers don’t produce the same sound as shabby-grade audio files. Even the best machine can’t save an audio file if it is not up to par. The demand for compressed and small files is often a result of the size crunch. However, compressed audio files lose their high- and low-frequency content, resulting in poor sound quality.

Compressed files have missed frequencies and other essential aspects that you may be unable to identify using headphones. To achieve this, it is most effective to use advanced music files designed for loudspeakers or subwoofers, containing all the frequencies and effects required. Experts recommend Lossless audio file formats like FLAC and AIFF due to their lossless nature.

Choose advanced apps that stream music from high-quality audio files if you plan to stream music from an app. Also, make the music app ensure that the streaming service is of the highest quality.

5. Reduce electrical impedance

Playing your favorite music with a subwoofer converts electric energy into sound. The sound quality drops dramatically when there is resistance in the connection. When a subwoofer plays music, its impedance has a certain degree of resistance; a high impedance decreases its efficiency. Because of this, the subwoofer cannot convert as much electrical energy into audio, resulting in distorted sound.

Several factors, including the magnetic and coil conditions and the control conditions, can cause higher impedance. Subwoofers produce bass, so you should ensure that the woofer works properly without excessive wear and tear. As well as checking the magnet and coil condition of the teeth, check their condition. For these parts to work properly, they must be in perfect condition.

You can also fine-tune the audio quality of the subwoofer control units to reduce impedance by checking the subwoofer control units. You should call an electrician if any of these parts are damaged. Calling an electrician will give you the best listening experience for your audio system.

6. Invest in sound-dampening materials

In addition to muddying up the sound, extra vibrations also affect the bass effect, which becomes blunt and lacks sharpness. It will produce damp bass sounds if the subwoofer vibrates excessively. Add dampening materials to the solution. Material that dampens vibrations is best for insulators.

Vehicular subwoofers usually have dampeners that cancel vibrations to produce maximum sound output. Furthermore, the bass effects raise the volume of the speakers. A dampener also enhances the sharpness and accuracy of sound. A common trend is to use a dampening enclosure lined up along a cubical or rectangular shape. In this design, internal reflections and parallel surfaces often deflect sound waves in the wrong direction.

It is a good idea to use acoustic foam, according to experts. The foam is designed to negate vibrations and absorb sound reflections. Thus, sound distortion is reduced without affecting bass output. The sides of the subwoofer box can be covered with acoustic foam. Acoustic foam can be applied to both sides of larger woofers to increase sound quality.

Sound and musical equipment stores or e-commerce sites sell acoustic foams easily. Plastering foam with hot glue works well.

7. Replace the cables

A woofer is one of many components important to the system. Its cables are equally important. Using old and rugged cables may result in poor sound output since they can’t transport electricity as efficiently as they should. Worn-out or low-quality cables should be avoided.

Furthermore, the older VC valves often cause audible sound distortions as they adversely degrade the electric signals. Cables of poor quality are also prone to the same problems.

When using electric cables, always choose reputable brands that offer premium quality. In addition, you can maintain the sound output by changing the cables every twelve months. Cables that have visible wear or tears should be replaced immediately.

8. Make sure the subwoofer is isolated from your floor

Subwoofers should not be placed directly on the floor. The poor sound output will result from this.

Subwoofers produce a lot of vibration, and it is often worse when they are placed directly on the floor. Moreover, directly placing the subwoofer on the floor will also cause reverberations that will prevent the subwoofer from performing as intended.

So, if you want to ensure that it is not affected by the floor, try to isolate it. It should not be placed directly on the floor. To maintain a small gap of at least three inches between the subwoofer and the speaker, you should use special subwoofer stands. It is also important to use air circulation to allow the subwoofer to work correctly, allowing you to hear the sound more clearly and precisely.

9. Upgrade the heatsink

Audio electronic appliances are especially susceptible to damage caused by heat. Subwoofers usually emit waves of sound. The result is that they generate a great deal of heat when they operate. The heat can damage woofers and their cones, resulting in sound distortions. Additionally, the amplifiers inbuilt into the device amplify electronic signals, resulting in more heat emissions.

The sound output will be improved by dissipating this heat. Furthermore, it extends the subwoofer’s shelf-life. Adding an extra heatsink to the subwoofer is the best way to go. You can do so if you prefer to purchase it offline or online. Heatsinks are now built into most subwoofers’ backs.

A more oversized or separate heatsink is an option if your woofer doesn’t have one. The woofer should be able to handle it if it can be mounted. Heat sinks can be attached to woofer sides with hot or industrial glue if you cannot use screws.

10. Locked Enclosures / Custom Boxes 

Many customers prefer custom subwoofer boxes. Neither of the methods above works if you enclose your woofer in a DIY box. Different steps must be followed, such as.

Ported Subwoofer Box:

Music listening experiences should also be considered when designing enclosures. Custom-ported boxes, for instance, are necessary if you want loud and deep bass tones.

The use of wholly enclosed woofers is not recommended. Instead, an amplifying soundbox with a ported design provides a great listening experience. A pit near the 50Hz region will have a louder bass or boom effect. You will benefit significantly from it.

Fill the subwoofer with polyfill.

Placing polyfill inside the enclosure box is another great idea. Using a compact subwoofer, you can boost bass sound output by using polyfill.

In the box, sound waves are slowed down by polyfill layers. The waves traveled farther because the tooth boxes grew larger. Deeper bass is the result of this effect.

Ensure that the box is filled from all sides using layers and polyfills. Layers will become lighter as you lift them upwards by attaching the thickest layer at the bottom. To prevent fibers from escaping from the box, attach cotton gauze on top. Use paper glue instead of glue if you’re using glue.

A tightly packed box should be avoided. It is possible that you will not achieve the desired results if you don’t follow these steps.

Choose a box with a more robust material

Long-lasting materials should be used if you need to use an enclosed box. As the woofer box expands, damages and degradation occur over time due to the airwaves within the sealed box.

The box is made from durable materials to last a long time and to offer great sound quality. Ported and leased boxes can both benefit from this strategy.

A box can be designed with fiberglass or MDF.


A subwoofer’s sound output can be enhanced significantly by amplifiers. Listening to clearer and louder music with a subwoofer amplifier is possible. On the other hand, those with a tight budget may not be able to afford amplifiers. Everyone cannot keep and maintain the amplifier, as they need more space.

To get a louder bass effect, you can adjust the speaker’s placement and fine-tune it to meet your needs. The crossover and phase settings can also be adjusted. You should also use premium audio files to get a great audio listening experience. Make sure you choose ported or polyfill-layered enclosure boxes of premium materials if you use enclosure boxes to amplify the sounds.


Q1: Can I improve the sound output of my subwoofers without using an amplifier? 

A1: Yes, you can enhance your subwoofers’ sound output without an amplifier. By adjusting placement, tuning, and phase settings and using high-quality audio files, you can achieve louder and clearer bass.

Q2: How should I position my subwoofer for optimal sound output? 

A2: Placing the subwoofer in a corner of the room generally provides the most bass output. However, consider placing the subwoofer in the center of the room for even sound distribution. Ensure there’s a bit of space between the subwoofer and the wall for better results.

Q3: How do I tune the subwoofer to achieve better bass output? 

A3: To achieve amplified bass, properly tune your subwoofer. Adjust the controls according to the manufacturer’s recommendations, avoiding excessive strain on the machine. This tuning helps you achieve louder and clearer audio.

Q4: What are phase and crossover settings, and how do they affect subwoofer performance?

A4: Phase and crossover settings are crucial for subwoofer performance. Phase settings ensure the subwoofer is in sync with other components, while crossover settings determine the frequency range each speaker handles. Properly set phase and crossover settings prevent sound distortion and ensure precise audio reproduction.

Q5: How can using high-quality audio files improve my subwoofer’s sound output? 

A5: High-quality audio files are essential for achieving the best sound output. Compressed files lack frequency details and may result in poor sound quality. Lossless formats like FLAC and AIFF preserve all frequencies. Using these formats and streaming services that offer high-quality audio enhances your subwoofer’s performance.

How To Choose A Subwoofer

How To Choose A Subwoofer | Buying Guide 2024

The best way to choose the right subwoofer depends on various factors, including sound quality and size, power, crossover, and room calibration.

You have to navigate a minefield when buying a subwoofer. A sub the size of a rhinoceros might not be a good fit for your living room if you want the best bass possible. This article explains how you can choose a subwoofer based on sound quality, volume, price, and whether or not you need a wireless subwoofer. Check out our best subwoofers article for our top picks.

For a comprehensive guide on understanding the role of subwoofers and their significance in your audio setup, check out our blog post on what does a subwoofer do?

Sound Quality

A subwoofer’s primary purpose is to increase bass, so it’s always a big question: will it do that? You can improve your bass with a dedicated sub, regardless of how much you spend. 

There will be a lot more meat to it, more richness, and more depth to it. Both movies and music benefit from subwoofers because they boost the low end.

When choosing a subwoofer, however, you’ll find out one important thing nobody tells you. As important as it is, sound quality is only one of the essential factors in choosing a podcast. 

Alternatively, we recommend you spend a lot of money on the most extravagant, loudest, and largest subwoofer you can find. One of the main things to remember is that you need to consider factors such as size, power output, frequency, etc. 

It is not just about having the best bass; it is about having the right balance of sound quality at this point rather than having just the best bass.

Subwoofer Size

How To Choose A Subwoofer by

When it comes to subwoofers, size matters; depending on the size of your driver, you’ll be able to achieve a wide range and quality of bass. Subwoofer drivers are basically speakers – circular cones that produce sound. 

As a result of the energy required to move bass frequencies through the air, it is not easy to do. Larger drivers will be able to put out more power than smaller drivers, which will, in turn, require a larger cabinet to accommodate the output. There is a question of how big it is.

Subwoofers are different, but there’s a good guideline here about how long they should be. You want to install a home theater or hi-fi system in an average-size room, between 150 and 230 square feet. A 12″ driver is the best choice for a subwoofer. 

There are a number of different sizes of drivers available, and this is likely to be the most common one, but it is also likely to be the most forgiving – both in terms of price and in terms of results. 

This generator will provide enough power to meet your needs without breaking the bank. The top subwoofer we recommend is the ELAC Debut 2.0 SUB3010 10”($451.60 on Amazon), which has a 10-inch driver, as do many other subwoofers we like.

While you can try subwoofers of any size, 12″ is a great starting point if you’re new to the world of subwoofers.

Subwoofer SizeRecommended Room Size
6.5 inchesSmall rooms up to 1,000 cubic feet
8 inchesSmall to medium rooms up to 1,500 cubic feet
10 inchesMedium rooms up to 3,000 cubic feet
12 inchesMedium to large rooms up to 5,000 cubic feet
15 inchesLarge rooms exceeding 5,000 cubic feet

These estimations are based on general guidelines and might vary depending on the subwoofer’s specifications and the acoustic properties of the room.

Power and Volume

A subwoofer with its internal amplifier is usually active, meaning it doesn’t require an external one. Subwoofers are powered by internal amplifiers, which are the device’s core. Choosing a good subwoofer requires understanding how power is measured in watts.

It is usually stated on the specs of subwoofers how many watts they produce at peak and at RMS. The peak can be ignored for all practical purposes. If you crank up a subwoofer to its maximum power, it will produce maximum power. Considering your ears are among the most important parts of your body, it would be unfair to expect you to perform that act frequently. The RMS wattage is the one that will give you the most information. 

Please understand that Root Mean Square, or RMS, is sometimes referred to as continuous wattage, which is short for Root Mean Square – but does not make us explain the math. When a subwoofer is driven at a reasonable volume for a period of time, you can get an idea of what kind of power it can produce when driven at a reasonable volume. 

In this case, let me give you an example of an inexpensive speaker that gives you fantastic sound for under $150, the Monoprice 9723. The unit has an RMS power consumption of 150 watts, which is typical for this range of prices and plenty powerful for most people to use without any problems.

Wattage does not equal volume, which is one of the most important things to remember. 

Subwoofers can always be turned down, no matter how powerful they are. The wattage figure should limit how hard a subwoofer can be pushed. Generally, the higher the wattage output, the more likely it is to play sound at higher levels that is clear, distortion-free, and free from noise and noise.

A higher wattage number will cost you more, so you should consider that. Most people will be satisfied with a wattage of 150-500 watts, which balances the amount of power output with an affordable price, which most individuals will find perfectly acceptable.

Wireless vs Wired Subwoofers

Most subwoofers must be connected directly to your amplifier and to a wall outlet to receive power. Power cables are used for the former, while RCA cables are used for the latter, usually included with subwoofers. Is it possible to go entirely wireless?

You can purchase a wireless subwoofer for $699 at Sonos. These devices work well with their audio sources when they are connected via Bluetooth or Wi-Fi. Companies like VIZIO and the Sonos Sub frequently make wireless subwoofers that connect directly to soundbars.

 You may not want to invest time in wireless subwoofers despite our praise. A single wire keeps your subwoofer from connecting to your amplifier, so you’re paying extra for simple things.

The second problem is that most wireless subwoofers operate within an ecosystem closed to the outside world. Sonos subwoofers work only with other Sonos products, so a sub like what I mentioned above can only be used with another. Later, if you upgrade your system, you won’t be able to use it.

A regular wired subwoofer is better if you intend to use speakers from multiple brands in your system. Ultimately, you’ll save money and get better sound quality. There is a place for wireless subwoofers, but they offer little versatility compared to their wired counterparts.

Frequency Range

It is essential to understand that every sound has a frequency – how high or low it is. Understanding frequency is essential for subwoofers, as frequency is measured in Hertz (Hz). Due to the characteristic of low-frequency bass notes, subwoofers that can reach the lowest possible frequency are considered outstanding subwoofers.

We know that humans have a hearing range of about 20Hz and a feeling range of about 10Hz, which is the range that rumbles your stomach when you hear something. 

A subwoofer’s performance will be enhanced if it can get close to these targets. Some very expensive subwoofers can reach a depth of 16Hz, like the $2,000 Power Sound Audio S3611. A good subwoofer should reach a frequency of 25Hz, although if a bass isn’t what you want, you can settle for a 50Hz subwoofer. You’ll have to pay more if you’re looking for a subwoofer with a lower frequency floor.

Note the highest frequency your subwoofer can generate when setting it up. Subwoofers begin to produce sound at this point, known as the crossover. 

It’s possible to manually set the crossover on most A/V receivers, guaranteeing better bass sound. Some hi-fi amplifiers have this feature, but we have yet to see it on a lot of them.

Front-Firing vs Down-Firing Subwoofers

There is a forward-facing main driver on a front-firing subwoofer. Down-firing subwoofers have their drivers mounted under the floor, facing down. You can choose one based on where you plan to place your subwoofer as there are very minimal differences between them. 

You should invest in a front-firing subwoofer if it will be near the main speakers. Both are equally good choices, but you don’t have to choose one.

Ensure you get a subwoofer with passive radiators to enhance your bass performance even more. Subwoofers with these vehicles can carry more bass overall because they are not powered and point out on the sides.

 Investing in a subwoofer with these features will cost you some extra money, but it’s ultimately worth it.

EQ and Room Calibration

Sound can uniquely respond to its environment more than any other type. It collects in corners and becomes muddy and indistinct when it encounters a room that could be better due to its slow, heavy nature. 

DSP technology (Digital Signal Path) is a technology that subwoofer manufacturers know about. Subwoofers operate in a way that improves and alters the sound before it is pushed out of them, thereby interacting better with the room. 

In general, DSP comes in two forms. EQ stands for Equalizer, a tool that allows you to boost or cut certain frequencies within a sound by adjusting its amplitude. Some subwoofers come with this kind of feature, which is usually adjustable over the phone, as it is on this $999 SVS SB-3000 subwoofer. 

Choosing presets for EQs is a great way to start if you’re unfamiliar with how to adjust them – no worries. The room calibration may not be necessary because you don’t need to mess with anything in that area.

During room calibration, a series of test tones are played through a microphone attached to a subwoofer. The subwoofer can adjust itself to fit the tones bouncing through the room, thanks to the microphone recording those tones as they bounce around. 

A significant boost in clarity and realism can be seen with this technology. It is almost certain that these upgrades will cost you more. For the most part, people don’t need them. A subwoofer under $500 is unlikely to have this feature if you want to get the most bass out of it.

Ported vs Sealed Subwoofers

Subwoofers are very strange when it comes to holes: they have a higher probability of having holes if they are more expensive. As the name implies, subwoofers with ported ports directly connect to the chamber interior through one or more ports. 

Ports are absent from sealed subwoofers. The majority of subwoofers on our list of the best available right now are sealed subwoofers, generally speaking, the best models on the market at the moment.

It is the sound quality that distinguishes seal subwoofers from ported subwoofers. The sealed subwoofers usually produce tight, even, controlled sound, while the ported subwoofers can produce large amounts of sound. 

Subwoofers with ports are not needed for small audio or home theater setups. You should consider a port-equipped one if you have a large room or want to spend a lot of money.

Hi-Fi vs Home Theater

The versatility of subwoofers makes them ideal for playing music, watching movies, and playing video games. A significant difference between a subwoofer for a hi-fi system and a subwoofer for a music system is that you usually don’t need to buy more than one subwoofer for an audio system. 

This isn’t just because one subwoofer will be sufficient for music – that’s for sure. However, the main reason is that most stereo amps cannot send sound from one subwoofer to another subwoofer because they cannot do so.

There is a difference between home theater and regular television. Surround sound systems often require two subwoofers to be played at once through A/V receivers, so this makes sense. 

Adding two subwoofers, the power doubles, and the sensation is the same that everyone who likes bass lusts over. There is a certain sensation associated with an engulfing bass hitting you right in the stomach as it comes from all angles, enveloping you completely. 

There are a lot of factors that can influence the sound quality of two subwoofers. Still, if you don’t mind experimenting and have a reasonable budget, you can achieve some fantastic results.

Cost of Subwoofers

If you plan on buying a subwoofer, you should spend at least $100. Several other price points have been heard as well, with mixed results. Subwoofers can be purchased for as little as $140, and if you spend a little more, you’ll often see fantastic results. Some real gems are in the $200-$1,000 price range, but many options are available.

Subwoofers are expensive. However, you’re paying more for power and output wattage when you’re over $2,000. Purchasing a subwoofer over $2,000 is unnecessary unless you have a massive room and an equally huge system. The chances of auditioning subwoofers at high-end audio stores are getting increasingly rare, so we recommend shopping online for them. 


Choosing the right subwoofer involves carefully balancing factors to achieve optimal sound quality and bass performance. From considering the size of the driver to understanding wattage and frequency range, each aspect contributes to creating a satisfying audio experience.

Room calibration, subwoofer type, and cost considerations further guide your decision-making. Finding a subwoofer that aligns with your preferences and budget will enhance your audio setup and immerse you in a powerful and rich bass world.


A common and balanced starting point is a 12″ driver. It provides sufficient power output without compromising sound quality and is generally forgiving in terms of price.

2. How does wattage relate to subwoofer volume? 

Wattage isn’t a direct indicator of volume but represents the limit at which a subwoofer can be driven without distortion. Balanced wattage, usually between 150-500 watts, offers clear and distortion-free sound.

3. Are wireless subwoofers a good choice? 

Wireless subwoofers can limit compatibility and tend to work within closed ecosystems. Wired subwoofers offer more versatility and often better sound quality, making them a better choice for most setups.

4. What is the significance of frequency range?

 A subwoofer’s frequency range indicates the low frequencies it can reproduce. Optimal subwoofers can reach frequencies around 25Hz, delivering a satisfying bass experience, especially for movies and music.

5. How do EQ and room calibration affect subwoofer performance? 

EQ allows adjusting frequency levels for optimal sound quality, while room calibration, utilizing DSP technology, tailors the subwoofer’s output to the room’s acoustics, improving clarity and realism in the sound.

How to Recone a Subwoofer

How to Recone a Subwoofer | DIY Guide for Improved Sound Quality

A powerful subwoofer is essential to any car’s sound system, regardless of its type. Subwoofers can hit some pretty low frequencies when they are brand new. However, they lose their ability to deliver the same sound as they age. Subwoofers’ performance decreases over time due to wear and tear. Your subwoofer’s limits are closer to being reached the louder and more often, you crank up the bass.

Subwoofer cones are highly susceptible to fatigue, making them one of the most crucial parts. Your sub can develop cracks and splits due to constant use and abuse. Subwoofers are unable to move air effectively once this occurs. If you continue using it, you will only exacerbate the damage caused by your fatigued subwoofer. 

External objects can physically damage a subwoofer by piercing the cone and eventually rendering it useless due to physical damage. A damaged cone can be repaired by various methods, fortunately. Take your old, tired speaker to an audio doctor in your area for a little tune-up to see if it will work any better. If you would like a more accessible and cheaper method to recone your subwoofer, here is a guide:


Subwoofer damage can be repaired through a simple process called reconing (except for damage to the magnet, frame, and enclosure). There are several steps involved in this process, but it essentially entails removing all the moving parts of a subwoofer, such as a cone and surround, spider, lead wires, voice coil, cone and surround, and moving parts. A subwoofer can be reconed in several different ways. 

Buying a complete kit for re-coning is the first method of re-coning. The prices for these kits can range from low to high. A more involved method would be to strip your subwoofer, requiring you to do more work on the machine. You must decide which is best for you based on your budget, experience, and time. A complete DIY guide to reconditioning your fatigued subwoofer is provided below.

How to Recone a Subwoofer | What You’ll Need

Step 8: Place Gap Spacers:

  • Once tinsel leads are in place, position gap spacers as needed.

Step 9: Attach the Cone:

  • Position the new cone, making sure it is flush against the top lip of the basket and snugly seated against the raised lip.

Step 10: Stick Surround to Basket:

  • Apply adhesive to the edges of the basket and attach the surround over the top of the cone.

Step 11: Apply Even Pressure:

  • Place several books on top of the frame to evenly press down the surrounds, ensuring a great, airtight bond.

Step 12: Allow for Drying Time:

  • Let the subwoofer dry for a couple of days, allowing the adhesive to set properly.

Step 13: Test the Subwoofer:

  • After the subwoofer has dried, you should be able to hear the difference in sound quality between the new and old components.

Step 14: Reinstall Subwoofers:

  • Place the reconed subwoofers back into their enclosures, ensuring they are securely mounted.

Step 15: Test Sound Output:

  • Put the car back on the road and test the sound to ensure that the reconed subwoofer is functioning correctly and producing the desired sound.

Following these step-by-step instructions will guide you through the process of reconing your subwoofer and improving its performance.

Common Mistakes to Avoid When Reconing a Subwoofer

While reconing a subwoofer can be a rewarding DIY project, people can make several common mistakes during the process. Here are some of the most frequent mistakes:

  • Lack of Patience and Rushing: Reconing requires precision and attention to detail. Rushing through the process can lead to misalignments, poor glue bonding, and other issues that could affect the subwoofer’s performance.
  • Inadequate Cleaning: To ensure good glue bonding, thoroughly clean the subwoofer’s frame, basket, and other components before applying new adhesive. Any residual old glue or debris can hinder the new components from adhering properly.
  • Improper Glue Application: Applying adhesive incorrectly or unevenly during the reconing process can lead to air leaks and compromised performance. It’s essential to use the right type of adhesive and to apply it evenly to ensure a strong and airtight bond.
  • Neglecting Alignment: Incorrectly aligning the voice coil, spider, and cone can lead to poor movement and distortion when using the subwoofer. Proper alignment is crucial for optimal performance.
  • Overstretching Surrounds: Stretching the surrounds too much during installation can lead to an imbalanced suspension, affecting the subwoofer’s performance and longevity. It’s important to be gentle when positioning the surroundings.
  • Incorrect Wiring: Reattaching the voice coil wires improperly or crossing them can result in short circuits or poor electrical connections, affecting the subwoofer’s functionality.
  • Need for Drying Time: Rushing to reinstall the subwoofer before fully dries the adhesive can result in poor bonding and misalignments. Giving the reconed subwoofer adequate drying time is crucial.
  • Ignoring Manufacturer Guidelines: Every subwoofer model may have specific reconing guidelines provided by the manufacturer. Ignoring these guidelines or not using recommended replacement parts can lead to suboptimal performance.
  • Using Wrong Parts or Tools: Using incorrect replacement parts, adhesives, or tools can lead to problems during the reconing process. Ensuring you’re using the right components for your subwoofer model is essential.

Subwoofer vs Speaker: 13 Key Differences and How to Choose?

Would it be necessary to add subwoofers to your pair of speakers? Do these components look similar? Whether you use a pair of speakers or a subwoofer along with the receiver, audio is reproduced as soon as it is connected to it. Subwoofers and regular speakers indeed have some key differences. 

A subwoofer differs from a speaker only in terms of the frequency range. Subwoofers handle Lower frequencies, also called sub-bass responses, while speakers handle higher frequencies.

You should know about a few other subwoofer features and their frequency ranges.

Differences Between Subwoofers And Speakers

Subwoofers and speakers produce audio, but from now on, there is no connection between them. It will be difficult for regular speakers to handle heavy bass and sub-bass. They are used in computers and televisions because they respond to mid-range and high-range frequencies. The components are suitable for producing voices, but you will notice something lacking if you listen to music.

Subwoofers are necessary for hearing the lower frequencies. Most music genres require deep bass to create a balanced sound, so subwoofers are designed for this purpose. A key difference between speakers and subwoofers is that you can only use speakers with subwoofers.

In most cases, the price of a subwoofer is a function of its frequency range. Subwoofers are designed for one thing, which is to produce lower frequencies. There is a price premium for professional subwoofers, but has lower frequency ranges. Less expensive subs can reproduce most types of music with frequencies between 20Hz and 200Hz.

A vent or port for the audio in the wood casing usually protects the sensitive component. Passive and active subs are also available. An active subwoofer is equipped with an amplifier, which differentiates them from passive subwoofers. It’s more expensive than passive systems but can improve sound quality.

Audio quality can be greatly improved by adding a subwoofer. Because the subwoofer can handle lower frequencies, this frees up the speakers to concentrate on producing mid and high frequencies. This is where they are more suited by default.

The sound will sound clearer, crisper, and fill more of the ‘sonic image.’ The difference between higher-grade speakers won’t be discernible to most casual listeners, but a high-quality subwoofer has a lower frequency range that is easier to hear. 


When it comes to sound systems, adding a subwoofer has various advantages.

  • Since the speaker strain is reduced, the bass is deeper, and the midrange sound is improved.
  • All frequencies are improved overall.
  • Using a subwoofer can turn up the volume without distorting your speakers.
  • Audio from a subwoofer tends to be sharper and clearer than from full-range speakers since it focuses on a separate frequency range.


The components of subwoofers can still cause some problems, even though they improve sound quality.

  • A subwoofer cannot be used on its own. A speaker must be connected for it to work.
  • There can be problems with sound quality when subwoofers are not well-designed. Even setting them up can be difficult.


Most TVs, computers, and smartphones have speakers. Passive and active speakers are both types of subwoofers. In contrast to passive speakers, active speakers are equipped with an amplifier. An amplifier also requires an external power source to power the speaker or subwoofer.

Both types of speakers produce a quality sound. There is no difference in the intensity or clarity of sound produced by high and low frequencies on speakers. Instruments and sounds within this range will be more pronounced as the lower frequencies are muted or barely audible.

When it comes to speakers, you can often only find them in pairs, unlike subwoofers, which come in singles. In contrast to mono sound, which comprises one speaker, surround stereo sound comprises two speakers, left and right. You can create surround sound by adding a subwoofer.


It starts with the price, which is one of the advantages of speakers.

Subwoofers can be expensive, even when replaced by factory-installed speakers.

In addition, a regular pair of speakers will still be able to reproduce most frequencies, but you will hear less bass.

You might not need a subwoofer if you use your speakers for certain purposes or if the music style differs.


Quality speakers have very few downsides, so long as you use them.

Firstly, deep bass won’t sound as good since speakers produce higher-range frequencies.

Low-frequency sounds can appear muffled, fuzzy, muddy, or unclear when speakers transmit lower-range frequencies.

It is also important to note that a loud volume can cause distortion or “clipping.”

How Subwoofers Work with Speakers

You will notice an immediate improvement in sound quality when subwoofers are used along with speakers. Because subwoofers handle lower frequencies, the speakers don’t have to worry about them. Thus, you will be able to focus the power of your speakers on the midrange and high-range frequencies.

How to Setup Subwoofers

It is not uncommon for people to put together subwoofers without much trouble, regardless of whether they have decided that the optimal quality of their audio depends on these devices or they want to hear more of the frequency spectrum. If you want the audio to sound perfect, you must do a little fine-tuning, but connecting the components shouldn’t take too long.

Subwoofer connections

Your home theater receiver can connect directly to the subwoofer. A cable is connected to both the output and input of the receiver and the subwoofer. A speaker cable will be needed if your receiver does not have an output for subwoofers. Speakers are connected to the subwoofer, and the receiver is connected to the subwoofer.

There are likely to be diagrams illustrating the various setup options that came with the subwoofer to make it easier to set up. If not, research is another way to ensure your subwoofers and speakers are set up properly.

Subwoofer adjustment

It is common for subwoofers to have more than two dials, although models sometimes have more dials when they are more expensive. You must locate the dials on the control panel’s volume and crossover frequencies. For the subwoofers to produce their highest ranges, the crossover frequency determines what frequency will be used for those subwoofers. If you are trying to get the range to be “exactly right,” you must spend some time playing around with the dial.

A subwoofer’s connection to a component will also affect where you set the crossover frequency. A trial-and-error approach is needed when adjusting the volume. If you are still determining what sound to seek, try adjusting the volume in the middle and moving it up and down until you are satisfied.

How to Test Audio Quality

Testing audio quality will follow the connection and fine-tuning of the subwoofer. Subwoofer placement will also have an impact on this. To prevent the subwoofer from being muted by furniture, knick-knacks, or other components in the room, it is necessary to ensure that any of these doesn’t block it, as this will mute the sound regardless of how optimal the crossover frequency and volume are.

If you need to check the audio’s sound quality, sitting where you like to listen to music is a good idea. A broad range of frequencies is also important when playing music. Musicians, including double bassists, cellists, and violinists, who cover a variety of frequencies in classical music, recommend it because of its variety of instruments.

You might need to rearrange the sound if you notice muting or the sound is unbalanced. Check the bass and high frequencies to ensure the sound is clear and crisp. You can download apps that will listen for you if you still need to figure out sound quality on your smartphone. After the app analyzes the different frequencies, you will be notified if any adjustments need to be made.


You wouldn’t be able to hear any audio from your devices if they didn’t have speakers. All your devices have speakers, including laptops, TVs, and smartphones. A subwoofer is necessary to enhance the bass, notably only with a wide range of frequencies.

You don’t need much experience to install a subwoofer. If you need lower frequencies, you will want to purchase these components, which can be more expensive than a pair of speakers. There will be an improvement in lower frequencies and mid-range and high frequencies. Subwoofers are a great addition to audio systems for audiophiles or bass lovers.


1. What is the main difference between a subwoofer and a speaker?

A subwoofer focuses on reproducing low-frequency bass sounds, typically below 200 Hz, to add depth and impact to audio. On the other hand, speakers cover a broader frequency range, including mid and high frequencies, providing balanced audio across the spectrum.

2. Do I need to add a subwoofer to my speakers?

Adding a subwoofer can significantly enhance your audio experience, especially if you want to enjoy deep and powerful bass. Subwoofers complement speakers by handling the lower frequency range, allowing speakers to focus on mid and high frequencies, resulting in clearer and more balanced sound.

3. Can speakers handle bass frequencies on their own?

While regular speakers can produce some bass frequencies, they may struggle with heavy bass and sub-bass responses. Speakers are designed to excel in mid-range and high-range frequencies, making them ideal for reproducing voices and instruments. Subwoofers are necessary for accurate and impactful reproduction of lower frequencies.

4. How does a subwoofer improve audio quality when used with speakers?

Subwoofers improve audio quality by taking over the task of reproducing deep bass frequencies, freeing up the speakers to focus on mid and high frequencies. This separation ensures a clearer and more detailed sonic image. The result is a more immersive and balanced listening experience, especially in music genres that rely on deep bass.

5. How do I set up a subwoofer and adjust its settings?

To set up a subwoofer, connect it to your receiver using appropriate cables. Adjustments can typically be made through the subwoofer’s control panel, where you’ll find dials for volume and crossover frequencies. The crossover frequency determines which frequencies the subwoofer handles. Experiment with adjustments to achieve the desired sound quality, and consider the subwoofer’s placement in the room for optimal results.

Subwoofer Vs Woofer

Subwoofer Vs Woofer- Which is Better?

A woofer or subwoofer is the only way to produce bass. Despite this, buyers are always confused about the difference between woofers and subwoofers.

Many believe both terms refer to the same thing, but that is not always true. Some are interested in determining which is best for them based on the differences between the two appliances. These appliances produce low-frequency sounds, which produce bass.

In almost all of the different audio parameters, they differ from one another. A detailed comparison of subwoofers and woofers will be presented in this article.

What is a Subwoofer?

Subwoofer Vs Woofer by

Subwoofers are loudspeakers that are capable of producing low-pitched audio frequencies of sound. Subwoofers are usually manufactured in a range of frequencies between 20Hz and 200Hz to reproduce low-frequency sound.

As a result, your audio system can benefit from rich bass. In the case of traditional sound systems, you need a subwoofer if they aren’t capable of producing low-frequency sound, which means it will not produce a significant amount of bass.

For those looking for the best subwoofers to enhance their home audio experience. Explore top-rated subwoofers that offer excellent performance without breaking the bank, ensuring a powerful and immersive sound experience for your home theater setup.


  • Stability: The low-frequency tones produced by a subwoofer improve sound quality. Subwoofers will reduce distortion in your audio system so that you will notice an improvement in the quality of your audio, and your audio system’s overall performance will also be improved.
  • Bass Enhancement: Subwoofers are used to increase bass in audio systems. To create a rich bass effect, it primarily focuses on low frequencies. A general woofer provides much worse bass than this speaker.


  • Space: It takes up a lot of space to install a subwoofer. A lack of space will make it difficult for places.
  • Power: The wattage consumed by a subwoofer is greater than that of a woofer. Plugs with high amperage will be required.

What is a Woofer?

Subwoofer Vs Woofer by

Woofers are loudspeakers that are capable of producing low-frequency sounds, which is also known as a woofer. Basically, woofers are only designed as passive bass drivers. A subwoofer, on the other hand, has a broader range of frequencies as compared to a regular speaker.

This band has a wide range of frequencies from 40 Hz to 2500 Hz. This makes it an ideal speaker for a variety of uses. It is an ideal audio system for home theaters since it can handle many audio types.


  • Overall Sound Quality: A woofer can improve the overall audio quality. In other words, it can enhance both low-frequency and high-frequency sounds.
  • Design: A woofer’s size differs from a subwoofer’s, as it is much more compact. Having a great sound and saving space is possible with it.
  • Frequency Range: 
  • Subwoofers have a frequency range of 200 Hz, whereas woofers have a range of up to 2k Hz.


  • Insufficient Specialization: Woofers cannot produce very low or high frequencies, so they are not specialized devices.

Subwoofer Vs Woofer: What’s the Difference?

Subwoofer Vs Woofer by

We will now show you how a woofer differs from a subwoofer.
If you are looking for the difference between subwoofers and speakers. we have another guide which will help you with subwoofers vs speakers which one is a better choice for home theater or outdoor?

The frequency ranges

It is generally believed that woofers can reproduce sound within the frequency range of 40 to 1000 Hz. However, a few woofer reproduces sound ranging are available that can produce sound between 40 and 2500 Hz. The woofers can be classified as mid-woofers due to their wide frequency range.

Subwoofers, on the other hand, can reproduce sound at frequencies between 20 and 120 Hz. Some specialized subwoofers also cover the 20 to 200 Hz frequency range.

Subwoofers are rated as subwoofers because they can produce “sub-level” frequency sounds. In addition, some rotary or propeller subwoofers produce a sound lower than 20Hz apart from traditional subwoofers.


Subwoofers have a larger structure than woofers. Several components make up a subwoofer, which is why this is the case. In a nutshell, the system is usually enclosed in a black enclosure that plays both the role of protecting the system as well as tuning its output. Besides the passive radiator, there is also a passive pressure release system that releases excessive pressure. A port vent could perform the same function as a radiator.

Within the main body, you will find the amplifier and woofer, which are the most important components. The woofer creates sound waves, while the amplifier amplifies sound levels. Deeper bass can be achieved with larger surface areas. Thus, subwoofers are larger than woofers.

Although some woofers are large in size when compared to the average woofer, these are the exceptions. A woofer is usually between 3 and 8 inches, whereas a subwoofer can be between 8 and 20 inches. In general, the size of a woofer can range between 3 and 8 inches in size.

Approximately how many drivers are there?

A woofer usually has more than one driver. The drivers of woofers typically have a 2-way or 3-way configuration. In a 2-way woofer, two drivers are used, a woofer and a tweeter. Three types of woofers are the woofers, the tweeters, and the midrange drivers that make up the 3-way woofer. Subwoofers with a super-tweeter are also available in 4-way configurations.

In contrast, subwoofers typically contain only one driver. Multiple drivers are available on some custom subwoofers. A single enclosure could have multiple subwoofers and drivers.

Consumption of electricity

Subwoofers consume more power than woofers. To reach the lowest frequencies, a subwoofer must draw more power from its amplifier, which is why it has hit the lowest frequencies.

The car’s lights will dim when your subwoofer hits a low bass note when your battery is low if the subwoofer is connected to your car sound systems. The reason for this is that excess power is needed.

Woofers, on the other hand, do not need to be able to produce such low frequencies. Therefore, they consume less power. However, the power consumption could increase slightly if a lower frequencies driver is used.

A subwoofer, however, consumes more power. A woofer generally consumes between 10 and 100 watts, while a subwoofer consumes between 200 and 1000 watts.

Driver powering

As far as powering the drivers is concerned, woofers are basically passive subwoofers. External amplifiers are used to power the woofers and regular speakers as well.

However, with active subwoofers, you do not have to worry about where to connect the amplifier because it comes with the driver. The dedicated amplifier boosts the input signal strength for the best performance from the subwoofer.

The high frequencies can also be filtered out using an integrated crossover.

For the same reason, subwoofers are slightly more complicated to set up than woofers.


This question cannot be answered definitively since it depends on your needs. It would be best to have a subwoofer for the best bass effect for low-frequency sound.

With this sound system, you can enjoy the heart-pumping bass effects that you will find at parties. Due to its suitability for home theater systems, it is ideal for this type of system.  Due to its wider frequency range, a woofer is the most suitable option if you are trying to improve the overall quality sound of your audio system. Hence, it’s better for car audio.


Can I use a subwoofer and a woofer together in my audio setup?

A: You can use a subwoofer and a woofer in your audio system for a more balanced and dynamic sound experience.

Which one is better, a subwoofer or a woofer?

A: It depends on your audio needs and preferences. If you want to reproduce low-frequency sounds accurate, a subwoofer would be better, while a woofer would be a good choice for overall sound performance.

Do I need a subwoofer or a woofer for my home theater system?

A: A subwoofer is highly recommended for home theater systems as it enhances the overall sound quality, especially for movies and music with heavy bass.

Q: Can a subwoofer replace a woofer?

A: No, a subwoofer cannot replace a woofer as they serve different purposes. A subwoofer is designed to reproduce low-frequency sounds, while a woofer handles a wider range of frequencies.

Q: What is the difference between a passive and an active subwoofer?

A: A passive subwoofer requires an external amplifier to power it, while an active subwoofer has a built-in amplifier. Active subwoofers are typically more convenient and easier to set up, while passive subwoofers offer more amplifier choice and customization flexibility. However, active subwoofers can be more expensive than their passive counterparts.

How To Connect Subwoofer To Soundbar

How to Connect Subwoofer to Soundbar | Step-by-Step Guide

Are you looking to add a subwoofer to your sound system to make it louder and better? Depending on which type of soundbar you are considering, some are sold independently, while others are sold with a subwoofer. The question is how to add a subwoofer to a soundbar without one if it doesn’t come with one.

A standalone subwoofer can’t be added to most soundbars because they don’t have ports. A native connection between a sound bar and a subwoofer can usually only be made when they are sold together.

While you might be able to jerry-rig an additional subwoofer to your soundbar, you’re probably better off purchasing a package that includes both a soundbar and subwoofer, such as the Sony HT-S350 (on Amazon).

Can a Soundbar be connected to a subwoofer?

It can be a challenge to connect soundbars and subwoofers. Many soundbars come without a subwoofer when you purchase them alone or with speakers. If you want a better sound, you add a subwoofer. Unfortunately, that isn’t as easy as it seems.

Soundbars connect to native speakers.

Some soundbars are compatible with subwoofers in their brand line. Some manufacturers will let you add an extra speaker or subwoofer to your soundbar if you use the recommended products.

For example, suppose you buy a Bose soundbar. In that case, you can consider purchasing a Bose subwoofer compatible with the device to match it, such as the Bose Bass Module 500 subwoofer (on Amazon) or the Bose Bass Module 700 subwoofer (on Amazon). Similarly, Sonos soundbars are compatible with the Sonos Sub (sold on Amazon) and can also be connected to this speaker. It is almost always impossible to add a subwoofer to these soundbars.

Soundbars with subwoofers

How To Connect Subwoofer To Soundbar by

You can also buy a soundbar and a subwoofer together if you want to connect them. The available soundbars on the market come with a subwoofer and extra speakers to produce a better stereo effect. Soundbars are often criticized for lacking bass because they have front-heavy sound and lack a good amount of front-heavy sound.

There are now a lot of soundbars from manufacturers that include both a subwoofer and external speakers since multiple-speaker packages have become increasingly popular. Many are wireless as well.

Check out our recommended soundbars if you’re looking for a soundbar with a subwoofer! These soundbars mostly have wireless subwoofers.

It is a good idea to purchase a soundbar package if you currently own a soundbar but cannot add a subwoofer. In terms of the options available at all price ranges, there are many great options to choose from, so you are sure to find one that meets your needs and produces high-quality sound.

Jerry-Rigged Subwoofer Addition to a Soundbar

To add a subwoofer to a soundbar, you must have the equipment, which is not a traditional method. To use this method, you’ll need a soundbar, subwoofer, receiver, and a mini mixer.

Your soundbar must be connected to a receiver first. A stereo mixer, like the Rolls MX42 Stereo Mini Mixer (available on Amazon), can then be connected to the left, right, and center channel pre-outs. The stereo mini mixer can then be connected to the sound bar, and the receiver can be connected to the subwoofer.

You’re sacrificing some sound quality with all these connections, so this is not the most convenient way to do it. If you do not already have these items, purchasing a soundbar and subwoofer package might be better.

Is it Necessary to Add a Subwoofer to a Soundbar?

Soundbar packages come in a wide variety, including soundbars with external speakers, soundbars with external speakers and speakers with only built-in speakers (including some with built-in subwoofers), and soundbar packages with an external subwoofer.

Depending on your type of soundbar, some will produce great sound without external speakers, and some will produce basic sound. It all depends on what you are looking for, but many people argue that a subwoofer is crucial to being able to experience the full potential of a soundbar.

You may wonder whether a soundbar needs a subwoofer if you are considering adding a subwoofer to it, in which case you will likely also need a soundbar package. 

Subwoofers Fill a Gap

Subwoofers serve various purposes, so it’s important to understand their function before deciding whether or not one is needed. Subwoofers are loudspeakers whose sole purpose is to produce lower-pitched audio frequencies, which are not produced by other speakers.

The low-pitched frequencies in your audio will be impossible to reproduce without a subwoofer. Subwoofers make a significant difference in the sound of any sound system, and members of any sound system who have used them know it.

Now, soundbars produce high-quality sound that’s an excellent alternative to traditional surround sound setups. They used to boost the sound of flat-screen TVs, but now, they’re an upgrade to basic flat-screen TV sound.

Movie and music enthusiasts know that subwoofers are essential to enjoy a full sound experience. In addition to being wireless and compact, subwoofers no longer resemble these big, bulky towers.

Soundbars Need Subwoofers

Most soundbars produce front-heavy audio, making sense since they are located in the front of the room, and that’s typically where your audio comes from unless you have external speakers. Most soundbars lack strong bass, too.

A subwoofer is essential to achieving a fuller, more robust sound with a soundbar. Using a subwoofer and a soundbar can make your living room, home theater, or media room sound better.

Subwoofers are typically placed in a corner or at the front of a room, depending on the room. In our guide on subwoofer placement, you can find some pointers on how to place each subwoofer based on the room size.


A broad range of sound quality is available for soundbars on the market. As soundbars have become more popular, manufacturers have worked hard to perfect ideal soundbars for consumers. This has resulted in more options, and many consumers consider pairing their soundbar with a subwoofer important.

We hope this article helped you see the different subwoofer options you have – whether you’re in the market for a new subwoofer, considering upgrading to a better soundbar/subwoofer package, or still undecided.

No matter what kind of subwoofer you choose, it’s essential to know how they fit into a sound system and how they work.

You probably won’t regret upgrading to a subwoofer/soundbar package, even if you’re not ready to upgrade your soundbar yet, especially if you’re a full-bodied music and movies fan.

Passive vs Active Subwoofer

Passive vs Active Subwoofers: What’s The Difference?

Excitement and overwhelming feeling are associated with setting up your own home theater system. It is essential to consider so many different factors. Initially, I had plenty of questions about building my home theater system. A subwoofer plays a particularly important role in a home theater setup, especially as I learned more about its importance. If you’re like me, you may be unaware of the different types of subwoofers available today. Passive and active subwoofers are the two most popular subwoofers for home theaters.

So, passive vs active subwoofers: what’s the difference? A receiver or amplifier is required to power passive subwoofers. Audio sources are the only thing active subwoofers need besides an amplifier and power source.

In this article, we will take a look at the main differences between the two types of subwoofers and how these differences may affect the way that you design your system.

What Is A Passive Subwoofer?

Passive Vs Active Subwoofer by

Passive subwoofers require external power sources such as amplifiers or receivers. Typically, passive subwoofers are preferred by home theater designers for large rooms with multiple speakers.

To produce sound, speakers, and subwoofers both require power from a source, which we explained in our guide. The amp or receiver you choose for passive subwoofers should deliver enough power to sustain the deep tones they produce. In addition, if your speakers are used in conjunction with the rest of your home theater sound system, you should consider how much power they will need.

Connecting all the pieces, a passive subwoofer might appear more complicated. You have both the source components and the additional amplifier, so you have two types of components. Therefore, more cabling will be needed.

Passive subwoofers are commonly used that are being incorporated into home theater systems for use with custom applications. A passive subwoofer is often mounted in a custom installation in the wall or inside the house. There are often advantages to passive subwoofers over active subwoofers. However, custom installation and a receiver with more power can add to the cost of passive subwoofers.

You can also link passive subwoofers together to create larger or more dynamic home theaters. Thus, you don’t have to worry about muddy bass or uneven distribution throughout the room.

Explore step-by-step solutions to address issues and ensure your subwoofer delivers the best possible performance in your home theater system.

What is An Active Subwoofer?

Passive Vs Active Subwoofer by

An active subwoofer uses an amplifier to produce power, also called a powered subwoofer. It is easiest to use a single active subwoofer setup with active subwoofers. This makes the placement of active subwoofers more important.

Subwoofers with active components are usually configured to optimize their performance. Active subwoofers offer a complete package for home theater enthusiasts and designers due to the built-in amplifier’s precise matching to the speaker’s power requirements.

There are fewer cables needed for active subwoofers than for passive ones. Additionally, it is usually easier to set up. Therefore, the power a subwoofer needs to operate is higher (watts) when compared to a passive subwoofer. Even though this amount may seem negligible when received on a power bill, it should still be mentioned.

Passive subwoofers are usually less expensive than active subwoofers, as they come with everything you need to get the best bass sound. However, Dolby Digital 5.1 did more than establish a new DVD standard. A designated bass channel is possible by Dolby Digital 5.1, adding five main channels and one Low-Frequency Effects (LFE) channel. A subwoofer using this channel is more likely to provide quality sound and more sound from a single unit rather than using multiple units. (This channel is available on DVD, Blu-ray, and much more.)

For tips on how to identify if a subwoofer is blown and troubleshooting techniques, refer to this informative guide. Recognize potential issues with your subwoofer and learn how to maintain optimal audio performance in your home theater setup.

Passive vs Active Subwoofers: Which is Better?

Passive Vs Active Subwoofer by

Each type of subwoofer has its pros and cons. Consider each factor if you want to choose the right subwoofer for your intended application. The right subwoofer must have good sound quality. Choosing a subwoofer that meets your needs is more important, regardless of its type. The six key features are, in addition, to sound quality:

  • Amplifier/Receiver: Is an external amplifier required for the subwoofer? Is it necessary to have a strong one?
  • Power: What is the wattage needed to power your subwoofer? Can you handle this power level with your receiver/amplifier?
  • Connectivity: Do you need specific types of cables, and how many do you need?
  • Expense: What is the price of the subwoofer? Is there a difference in price between certain types? Remember to include all required components in your budget.
  • Setup: What is the ease of setting up the subwoofer? How complicated is the setup? Can it be plugged in and played?
  • Design: Is your subwoofer equipped with any features? How easy is it for you to integrate your subwoofer into the décor of your home? Is a more customized approach what you’re looking for?

The following criteria can be used to compare passive and active subwoofers.

Passive subwoofers

Passive subwoofers do not have built-in amplifiers, as previously discussed. Several factors can affect how they are powered and the components they require.

Pros of passive subwoofers:
  • Design: A passive subwoofer allows you to configure your home theater system most comfortably.
  • Power: Besides requiring less power (watts), these subwoofers have a minimal impact on your power bill.
  • Expense: As a matter of fact, passive subwoofers are usually cheaper than active subwoofers since they do not include as many components as their active counterparts do in one unit.
  • Setup: Since most receivers/amplifiers today have a subwoofer output, this product works with almost any receiver or amplifier.
  • Connectivity: A large home theater setup requires multiple subwoofers, so passive subwoofers are your best choice.
Cons of passive subwoofers:
  • Expense: The project’s cost may increase significantly depending on the size and types of components needed.
  • Setup: A passive subwoofer is connected using a cable that supplies the power and the signal. Therefore, it is necessary to use a high-quality cable when connecting a passive subwoofer.
  • Power: To ensure sufficient power is supplied to your speakers and passive amplifier, consider the full load on the amplifier.

Active subwoofers

In an active subwoofer, everything you need is already in the box, saving you from buying extra parts. In comparison to passive subwoofers, what are the advantages?

Pros of active subwoofers:
  • Connectivity: If a home theater system requires only one subwoofer, an active subwoofer is the best option to use for the subwoofer.
  • Setup: There is no need to connect a special or extensive amount of cabling to the system, which makes setup extremely simple and easy.
  • Amplifier: You won’t have to research the best components for an active subwoofer because all the necessary components are built-in.
  • Design: Typically, active subwoofers are built to maximize the use of LFE channels to achieve optimal bass performance from a single speaker. The cable can be placed away from the receiver since only audio signals are provided. Due to their compact size, active subwoofers are easy to place, ensuring the most natural sound.
Cons of active subwoofers:
  • Cost: The cost of an active subwoofer is usually higher than a passive subwoofer’s.
  • Power: Your utility bill could be affected if you use active subwoofers constantly.
  • Compatibility: You need a receiver or amplified system with a subwoofer pre-out port.
  • Design: Because your surround sound system should use only one active subwoofer, placement becomes increasingly essential with this type of system.

Connecting subwoofers wirelessly

When it comes to electronics, wireless connectivity is becoming more popular. Your subwoofer is included in this. Active subwoofers are the only subwoofers that offer wireless connections natively. This feature may be integrated into some of the newer models. For older models with AV processors, home theater receivers, or LFE ports, wireless transmitter/receiver kits are also available. 


Active subwoofers are today’s most popular type of subwoofer for home theaters, but the choice is ultimately up to you. The active subwoofer offers a quick and easy setup, all-inclusive features, and excellent performance – making it the perfect addition to your home theater system.

How To Tell If a Subwoofer Is Blown

How To Tell If A Subwoofer Is Blown: Detecting Damage and Exploring Solutions

Home theaters sound great with subwoofers. A subwoofer or two can make a huge difference in a home theater, but what happens when they stop working? Is it irreparably damaged? Is it possible to fix it?

How To Tell If Subwoofer Is Blown? When a subwoofer blows, it is a result of being either overloaded with power or overloaded with distorted audio signals. The sound of your subwoofer, the movement of the woofer, and the presence of a blown coil can be used to determine if the coil has blown.

Ensure your sub has not blown by listening to the sound at a low volume. The subwoofer is partially blown if distorted and completely blown if no sound ever comes out. Before jumping to conclusions, check the cable to which the subwoofer is connected before assuming otherwise.

For a deeper understanding of subwoofer types and their functionalities, explore the comparison between passive and active subwoofers. Gain insights into the differences between these two types and make an informed decision on the subwoofer that best suits your audio setup.

You’ll need to remove the cover to access the cone to test the woofer’s movement. To assess the damage to the cone, carefully move it with two hands.

  • The item is most likely damaged if it doesn’t move at all when you try to move it.
  • This is also another sign that there may be damage if it is extra wobbly.
  • It is a particular sign of a blown subwoofer if you hear scratching sounds.
  • It is also possible to detect a blown coil by using a multimeter. Multimeters can be used to measure voltage, resistance, and current, which can help one determine if electrical resistance is absent by measuring voltage, resistance, and current.

If your subwoofer displays any of these symptoms, it is likely blown. The first step is to evaluate the situation thoroughly. To decide what to do next, you must first understand the severity of the damage.

Subwoofers: What Happens When They Blow?

How To Tell If a Subwoofer Is Blown by

Suddenly, your low-end sound stops working, and you enjoy your home theater system. There may be a lot of softening or distortion in the sound. The low-end doesn’t sound, or it may sound weird and distorted. 

Subwoofers are one of the most important parts of home theater systems, so whatever is causing you to think they’re blown can be devastating.

Subwoofers have been damaged or blown by either too much power or signal. Overpowering your subwoofer with too much power is another cause of damaged subwoofers.

Distorted or clipped signals

You can easily damage your subwoofer when you turn up a distorted signal. Subwoofers do not like distorted or clipped signals. It may take a long time before your signal begins to distort and cause damage before you realize it is distorted.

Power is too much.

Subwoofers are often blown because too much power is applied to them, and this can often be a source of damage. Subwoofers can only handle so much volume, even when there is a lot. In extreme cases, it may be forced to function beyond its limits, resulting in damage due to too much pressure.

It is essential to ensure that the sound is clear and distortion-free even at extra high volumes, even though subwoofers are intelligently designed to withstand even more power than their specified RMS (root mean square) ratings.

Ensure your subwoofer(s) receive the right amount of power continuously by knowing their RMS wattage if you don’t already know it.

For additional insights on optimizing your subwoofer performance and ensuring its longevity, explore this informative guide Reduce Subwoofer Vibration Through Walls. Discover techniques to reduce subwoofer vibrations and maintain an optimal audio experience in your home theater setup.

Testing a blown subwoofer in different ways

To determine how much damage has been caused to your home theater’s subwoofer, it’s important to assess the unit when it appears to have blown fully.

In case of a subwoofer blowout in your home theater, it’s essential to know what types of damage typically occur when it blows. A blown subwoofer can be tested in three ways.

  • Sound test. Does it clip, distort, etc.?
  • Cone movement should be tested.
  • Test electrical resistance with a multimeter.

For more information on how to perform these tests without causing any more damage to the subwoofer, read on to find out how to accomplish these tests.

Sound test

It is an excellent indicator of the extent of the damage done to your subwoofer if it produces a loud sound. Full or partial subwoofer blowouts produce the following sounds:

  • Almost no sound – If your subwoofer is wholly blown, then it is most likely that it has been damaged. Cables and audio sources should be tested. Before making any conclusions, check that these are functioning correctly.
  • Distorted partial sound – You probably have a partially blown subwoofer if your subwoofer produces weak, distorted sound at any volume.

Cone Test

Subwoofer cones can be easily accessed to diagnose the damage. For a subwoofer cone to move fluidly, it is built with a suspension system, and you can easily identify the cone when it is out of place by using your hands. The following symptoms might occur if you lightly press down on the subwoofer cone using two indicators:

  • No movement in Cone – When a cone cannot move, it’s an indication that damage has occurred.
  • Wobbly cone – The suspension system of a cone that lurches has been seriously compromised.
  • A scratchy noise – 
  • There has been damage if you move the cone with your hands and make scratchy sounds. Any other equipment in your home theater system should be removed before this equipment is removed.

Use a Multimeter To Test electrical resistance.

Having a multimeter on hand will let you know if a subwoofer’s coil is damaged, which is essential to know. You should check electrical resistance with this device (also known as ohms; symbol = Ω).

A damaged coil would have zero electrical resistance or would not stay in place if the reading was not stable, depending on the condition of the coil. 

A subwoofer’s electrical resistance or ohms can be measured in the following ways:

  1. If there is a power source for the subwoofer, disconnect it.
  2. The subwoofer audio input must be disconnected.
  3. The subwoofer must be removed from its enclosure unless an external amplifier or receiver powers it.
  4. The multimeter should be connected to the two probes. Switch on the multimeter and measure ohms (Ω)
  5. Positive leads should have the red probe inserted, and negative leads should have the black probe inserted.
  6. Multimeters are then used to measure resistance. It is usually necessary to round up to the nearest whole number when determining the value for the correct resistance.

Your Subwoofer Blown? Here’s what you should do

Damage to a subwoofer is exceptionally stressful, but once you know it has been damaged, you should respond as soon as possible.

Your home theater system must be deactivated before removing the subwoofer. This may cause damage to your other equipment if you keep it in place, which can be even more problematic. Due to this, you should altogether remove it.

If your subwoofer is in poor condition, you should seek the advice of an expert. You can obtain a warranty for a relatively new subwoofer. Disassemble the subwoofer only after you have checked this!

Getting multiple people to examine the damage is better than doing it yourself. Consider getting a second and third opinion, whether you consult with a trusted friend or take it to Best Buy’s Geek Squad.

The last step is to decide how you will proceed without your subwoofer. Would a new one be a good investment for you? What would you do if you weren’t able to have it? Is it possible to fix it?

There may be another option to consider other than buying a new subwoofer. Find out what works best for you by reviewing all of your options.


A blown subwoofer can be a frustrating setback for your home theater experience. Recognizing the signs of damage early can help you take timely action and prevent further harm to your equipment. 

Whether through sound tests, cone movement assessments, or using a multimeter to check electrical resistance, diagnosing a blown subwoofer involves careful examination. Remember to disconnect power sources and audio inputs before conducting any tests to ensure your safety.

Don’t rush to conclusions if you find that your subwoofer is indeed blown. Depending on factors like warranty coverage and the extent of the damage, consider seeking expert advice or a second opinion. 

It’s essential to weigh your options, whether repairing the subwoofer, getting a replacement, or exploring alternative solutions. Ultimately, your goal is to restore optimal sound quality to your home theater setup.


Q1: What causes a subwoofer to blow? 

A1: Subwoofers can blow due to excessive power or distorted audio signals. Overpowering the subwoofer or subjecting it to distorted signals can damage the speaker’s components.

Q2: How To Tell If A Subwoofer Is Blown? 

A2: Signs of a blown subwoofer include no sound output, distorted or weak sound, lack of movement in the subwoofer cone, wobbly cone suspension, scratchy noises when moving the cone, and zero or unstable electrical resistance when measured with a multimeter.

Q3: Can I repair a blown subwoofer? 

A3: Depending on the extent of the damage and the warranty status, it might be possible to repair a blown subwoofer. Seeking professional advice and exploring repair options can help you determine the best action.

Q4: Should I conduct tests on a blown subwoofer myself? 

A4: Approaching testing cautiously is advisable, ensuring you disconnect power sources and audio inputs first. However, seeking guidance from experts or technicians is recommended for accurate diagnosis and safety.

Q5: What should I do if my subwoofer is blown? 

A5: If you confirm that your subwoofer is blown, disconnect it from power and seek expert advice. Check if the subwoofer is under warranty, and consider consulting multiple sources for opinions. Decide whether to repair, replace, or explore alternative solutions to maintain the audio quality of your home theater setup.

How To Wire A Dual Voice Coil Subwoofer

How To Wire A Dual Voice Coil Subwoofer or Speaker

A dual voice coil speaker system (typically a subwoofer) can be confusing. There’s one more problem when it comes to dual voice coil speakers because if you don’t know how to select or wire them in the right way, you may end up getting less sound & power than you expect!

The following is a how-to guide I have compiled to assist you if you are having trouble figuring out your way around. It includes detailed diagrams, answers to several common questions, and more.

Are you looking for instructions on how to wire a dual voice coil subwoofer or a recommendation on the type of amplifier that is right for you? For more information, you can read on.

What is a dual voice coil speaker?

Single voice coil speakers have one voice coil winding, one wire, and one wire terminal, but dual voice coil speakers have two voice coil windings, wires, and terminals. The speaker’s cone rests inside the magnet with a small gauge wire wound around a bobbin (tube). A musical signal causes them to produce sound.

There are almost no differences between single voice coil speakers and dual voice coil speakers, most often subwoofers. It comes down to their design and how they’re used which makes the difference.

How To Wire A Dual Voice Coil Subwoofer

Series and parallel wiring are two ways to wire your subwoofer. Parallel wiring attaches the positive of coils A and B to individual terminals on your amp, while serial wiring connects all four terminals together, making them work as one unit. The negative aspects of their relationship will be channeled through a single method, but the positive aspects will be shared.

Dual Voice Coil Subwoofers Can Be Wired In Series

You need to connect the positive and negative terminals for the second pair of coils. Since the power is split between coils A and B, series wiring has a higher impedance than parallel wiring, which reduces your overall wattage.

Dual Voice Coil Subwoofers Can Be Wired In Parallel

It is just a matter of connecting coil A’s negative terminal to the output channel of your amplifier and repeating this for coil B. 

In series wiring, the negative and positive are connected together. With parallel wiring, you get a slightly higher output overall since you have half the impedance compared to serial wiring. 

Understanding the difference between series and parallel wiring when wiring a dual voice coil subwoofer is helpful. 

It would certainly be best to use serial wiring instead of parallel wiring if you intend to reduce your energy bills. This is because you are only using one channel and occupying half of the total power of parallel wiring. 

It is important to note that a parallel connection will be the best option if what matters most to you is the sound quality or if your amplifier can provide you with more power per channel.

Dual voice coil subwoofers vs. Single voice coil: what’s the difference?

How To Wire A Dual Voice Coil Subwoofer by

ere’s a comparison table highlighting some differences between single and dual voice coil subwoofers:

AspectSingle Voice Coil SubwooferDual Voice Coil Subwoofer
Number of Voice Coils12
Wire TerminalsOneTwo
Wiring OptionsSeriesSeries or Parallel
Impedance OptionsTypically 4 or 8 ohms2, 4, or 8 ohms
Flexibility in WiringLimitedMore options available
Amplifier CompatibilityMay limit optionsMore flexible
Power HandlingSimilar to DVC but limitedGreater flexibility
Ohm Load MatchingLess versatilityBetter matching options
Usage in Multiple SystemsMay be restrictiveMore adaptable
CostGenerally lowerSlightly higher
Suitability for Different AmpsMay not match requirementsBetter adaptation

These are the parts of a standard speaker or subwoofer:

  • Magnets are attached to metal baskets that hold speaker parts
  • Magnet with a large capacity
  • Surround the speaker cone
  • A dust cap and surround for the speaker cone
  • The bobbin for the voice coil (the tube where the coil is wound)
  • The voice coil assembly is suspended by a “spider” that is stiff but flexible
  • A magnet contains a coil of tightly wound wire of a small gauge and a long length enclosed in a gap.
  • Leads & connectors for voice coils

A single voice coil subwoofer has only one winding of the speaker coil, while a dual voice coil subwoofer includes a second winding in the bobbin, with the same Ohm rating.

The speaker wire terminals and the second pair of wire leads have also been added.

Related: Subwoofer vs Speakers.

Can dual voice coil speakers perform differently?

Dual voice coil models have no direct performance differences compared to single voice coil models. It has some advantages, as I’ll explain in a moment.

There is a slight price increase for dual voice coil subwoofers compared to their single voice coil counterparts, but not by as much as you might expect. There are usually similar ratings for power handling (always double-check to be sure), but there might be a slight variation from one model to another.

When designing speaker boxes, you should be aware that dual voice coil speakers will typically have slightly different Thiele/Small parameters. In a speaker box or audio crossover, thine/small parameters determine how a speaker behaves when it is placed in certain conditions.

Which is better, single or dual voice coil subs?

A single or dual voice coil speaker or subwoofer isn’t the “best” choice.

A single or DVC subwoofer is better suited to your needs according to a combination of factors:

  • An amplifier’s minimum load rating (Ohms)
  • A stereo amp or a bridgeable amp
  • If you are going to be using speakers or subwoofers, you need to know how many you’ll have.

Home stereo amplifiers may not be bridgeable in many cases, unlike higher-power car amplifiers. It is important to remember that you should never assume your amplifier can be bridged – always check!

Dual voice coil subwoofer Pros

Many systems work fine with standard subwoofers (single voice coil). On the other hand, dual voice coil subwoofers offer advantages and flexibility that single voice coil subwoofers cannot match.

1. Max. Amp power

There are certain power ratings for car amplifiers (in Watts) when connected to specific speaker loads (in Ohms). Typical power ratings for mono amplifiers are as follows:

  • A speaker load of 4 ohms delivers 350W RMS
  • The RMS power is 600W at 2 ohms
  • RMS power of 1,000W at 1 ohm

If you want only one subwoofer and one bass setup (mono), let’s say. Because you’re usually only able to find 2 ohms or higher subwoofers, you’d be limited to 600W from the amp.

In theory, it would be possible to add a 2nd 2-ohm subwoofer to the setup and wire them up in parallel. However, any such setup would require a bigger box, more money, more space for installation, and so forth.

To allow the amp to put out its full power, it may be necessary to use a 2-ohm DVC subwoofer wired in parallel to the amplifier. Without this, your amplifier will never provide the power you were hoping for when you bought it.

This is certainly true in the modern era, where many class D amplifiers can handle an impedance of 1 ohm or higher.

2. Choosing the right amplifier channel and how to set it up

It is not possible to bridge all amplifiers, as I mentioned earlier. It’s a big problem if you’ve got a single amplifier with four channels. What are the best ways to power a subwoofer without buying an extra amplifier?

The power of a dual voice coil subwoofer can be driven with a single channel for each voice coil to guarantee that the subwoofer receives enough power to transmit the sound to the speakers. In addition to this, if you want to have a potent system, you may be able to have one amp per voice coil, whether it is a single or multiple subwoofer system.

Dual voice coil subwoofers can be driven with enough power using one channel for each voice coil. It’s also possible for multi- or single-subwoofer systems to use one amp for each voice coil.

3. Multi-subwoofer/amp impedance matching

Your amp’s Ohms load depends on which subwoofers are connected in series or parallel when several subwoofers are wired to the same channel.

In addition to offering more options, dual voice coil subs can match your amp’s minimum load rating much better thanks to their ability to offer a greater range of total Ohm load combinations.

4. Use them for home stereos and car stereos

Because 8-ohm subwoofers do not have the same power as a 4-ohm speaker, 8-ohm subwoofers cannot be used effectively for car audio. Since car subwoofers with 2 or 4-ohm ratings do not meet the minimum amp specification, they cannot be used with home stereo amplifiers.

In case of overheating, shut down, or overheating, a home amplifier can be permanently damaged.

In this case, double voice coil speakers offer a unique advantage, as they can be used both in a car or at home:

  • Home stereo wired in series for 8 ohms
  • Car stereo amplifiers can be connected in parallel to 2 ohms or use a single 4 ohm

You will be able to use speakers when you aren’t otherwise able to use them if you get a great price.

How to choose and match a dual voice coil subwoofer

Several things need to be considered when choosing dual voice coil subwoofers:

  • If you are interested in high power levels, you should check your amplifier’s minimum speaker load (Ohms rating)
  • Using how many subwoofers

It’s easy from there! You can figure out the correct subwoofer configuration using my wiring connection diagrams below.

If you want to get the minimum speaker load and maximum power rating Ohm load for your amplifier, you must consult the owner’s manual (or labeled printed instructions). The next step would be to pick the appropriate number of dual voice coil subwoofers that can be wired to match the amp’s preferred amount of output.

Common Mistakes When Wiring Dual Voice Coil Subwoofers

One common mistake people make when wiring dual voice coil subwoofers is mismatching the impedance or incorrectly configuring the wiring setup. Here are a few common mistakes:

  1. Impedance Mismatch: Connecting the subwoofer in a way that doesn’t match the amplifier’s minimum impedance requirements can lead to poor performance or even damage to the amplifier. This might happen by wiring the coils in a way that creates an impedance load too low or too high for the amplifier.
  2. Incorrect Wiring Configuration: Choosing the wrong wiring method (series or parallel) based on the amplifier’s capabilities or desired outcome can significantly impact the subwoofer’s performance. Using series wiring when parallel is needed or vice versa can affect power handling and sound quality.
  3. Assuming Amplifier Compatibility: Assuming that any amplifier can handle any configuration of dual voice coil subwoofers can be a mistake. Not all amplifiers are designed to work with the full range of impedance options offered by DVC subwoofers.
  4. Incomplete Understanding of Wiring Options: Lack of understanding regarding the differences between series and parallel wiring can lead to suboptimal setups. People might choose a wiring configuration without considering how it impacts power handling, impedance, or the overall sound output.
  5. Neglecting Ohm Load Matching: Failing to consider how different wiring configurations affect the total Ohm load presented to the amplifier. This can lead to underpowering the subwoofer, reducing its efficiency, or potentially damaging the amplifier.

Avoiding these mistakes involves thorough research, understanding the amplifier’s specifications, knowing the subwoofer’s capabilities, and carefully following the correct wiring diagrams or guidelines provided by the manufacturer. It’s important to double-check and ensure that the wiring setup aligns with the amplifier’s requirements for optimal performance and longevity.


In conclusion, wiring a dual voice coil subwoofer or speaker can be confusing, but it is easy to do once you understand the process. The key is to know the difference between series and parallel wiring and to choose the best wiring option based on your amplifier and sound quality needs.

Dual voice coil speakers have two voice coil windings, wires, and terminals, while single voice coil speakers have only one. Dual voice coil subwoofers offer advantages and flexibility that single voice coil subwoofers cannot match.

When selecting a subwoofer or speaker, it is important to consider factors such as an amplifier’s minimum load rating, whether it is a stereo amp or a bridgeable amp, and how many speakers or subwoofers you will be using. By following the guidelines outlined in this how-to guide, you can successfully wire a dual voice coil subwoofer or speaker and achieve optimal sound quality.


What is a dual voice coil speaker, and how does it differ from a single voice coil speaker?

A dual voice coil speaker has two voice coil windings, wires, and terminals, while a single voice coil speaker has only one. Dual voice coil speakers, such as subwoofers, have two positives and two negatives, which can be wired in series or parallel to achieve a desired impedance level.

How do I wire a dual voice coil subwoofer?

You can wire a dual voice coil subwoofer in series or parallel. Series wiring involves connecting the positive and negative terminals for the second pair of coils, while parallel wiring involves connecting the negative terminal of coil A to the output channel of your amplifier and repeating this for coil B. The wiring method used will depend on your specific needs and goals.

Can dual voice coil speakers perform differently from single voice coil speakers?

Dual voice coil models have no direct performance differences compared to single voice coil models. However, dual voice coil subwoofers offer advantages and flexibility that single voice coil subwoofers cannot match.

Should I use series or parallel wiring when wiring my dual voice coil subwoofer?

The wiring method used will depend on your specific needs and goals. Series wiring has a higher impedance than parallel wiring, which reduces your overall wattage, but it can be a good option if you are looking to reduce energy bills. Parallel wiring provides a slightly higher output overall and may be a better option if you are looking for improved sound quality or if your amplifier can provide more power per channel.

What factors should I consider when choosing between a single or dual voice coil subwoofer?

When choosing between a single or dual voice coil subwoofer, you should consider factors such as an amplifier’s minimum load rating, whether you are using a stereo amp or a bridgeable amp, and how many speakers or subwoofers you will be using. It is also important to remember that you should never assume your amplifier can be bridged – always check!

How To Fix A Subwoofer With No Sound | Troubleshooting Guide

Need help fixing your subwoofer with no sound?

You will find a lot of helpful information in this article. 

The bass frequencies produced by subwoofers can be heard in home theaters, game rooms, and recreational areas not available to regular speakers. 

There are two types of subwoofers: low-frequency loudspeakers and high-frequency loudspeakers. Sound systems can incorporate subwoofers as part of the system or as stand-alone components.

The following instructions will help you fix a home theater subwoofer that doesn’t work. You should inspect each subwoofer part very carefully before you start. Before you start, pay more attention to every aspect of your subwoofer! Subwoofers connected to TVs or audio systems are connected to their subwoofer outputs. A working power outlet must be connected to the subwoofer’s power cord to allow the subwoofer to receive power.

If you looking for the best subwoofer in the specific budget range we have the best review guides under $500. Explore top-rated subwoofers that offer excellent performance without breaking the bank, ensuring a powerful and immersive sound experience for your home theater setup.

Sometimes, you might only need to consult a professional if your subwoofer is working. Many sound system problems can be solved by changing the signal source. Here are some things you can check to see if the subwoofer or amplifier is the problem:

Does every speaker have a secure connection? 

Make sure all cables are disconnected and then reconnected.

Has the power been turned on?

An LED light indicating that the subwoofer is powered should be on your subwoofer.

Check your amplifier’s setup menu if it has a crossover control (most integrated amplifiers have this in the setup menu if there is no power or a receiver without a subwoofer output). If that is the case, you must ensure that the crossover frequency control is switched to the “off” position.

Can you hear anything from your subwoofer?

Ensure your stereo system or TV speaker settings are correct before using the subwoofer. It is impossible to use a subwoofer with incorrect speaker settings. If your speaker settings need to be changed, you may need to do so. You can find more information on your stereo system or TV instructions. Depending on your stereo receiver, you can choose a different sound field.  

Your amplifier may have a crossover control (found in the setup menu of most integrated amplifiers) if no sound or distorted sound is coming from the speaker. Set the crossover frequency control to “off” if so.

Plugging in and securing all cables is a must. Make sure your speaker cables are connected correctly.

What is the status of the subwoofer? Switch on your power by checking the power switch. Ensure that a button isn’t connected to the extension cord if you’re using one.

For a more in-depth understanding of subwoofer types and their functionalities, explore the comparison between passive and active subwoofers. This guide will provide valuable insights into the differences between these two subwoofer types, helping you troubleshoot and optimize your audio setup for the best performance.

Why Does A Subwoofer Stop Working?

Subwoofers stop working when no signal is received at the speaker.

Voltage surges can damage electronic components, including amplifiers and power supplies. If this occurs, fuses can blow, or capacitors can fail to provide the sound system with the necessary voltage.

The sound system contains several parts that are connected by loose cables. Your amplifier or subwoofer could have a damaged connection. A damaged speaker plug end could also cause the problem.

It is possible to produce sound from a system with only one speaker without drawing much power from the power supply. On the other hand, multi-speaker sound systems require more power because they draw more current. An overworked or undersized power supply can prevent a capacitor from failing.

You’ll need an external amplifier if you want your passive subwoofer to work. Home theater setups can use passive subwoofers with an external amplifier connected to the receiver’s preamp outputs. With this configuration, the amplifier power for the subwoofer does not have to be provided by the receiver.

What Does A Subwoofer Cost?

1) The manufacturer should be contacted if there is a problem with electronics that you cannot resolve on your own.

A new subwoofer may be better if the old one is over five years old.

A unit may need more repairs or replacements than it is worth if its electronic components are old or have a limited life span.

2) consult a professional electrician if you need a new power supply.

3) Contact your manufacturer to find an electrician in your area.

Can you build your own subwoofer?

1) It is important to note that a subwoofer is the most suitable type of DIY speaker because it is easy to make and demands only moderate materials.

2) A reasonably suitable speaker enclosure and an amp are The basic components of your DIY subwoofers.

Wood, screws, glue, paint/stain, drill bits, and an amplifier are just some materials you will need to build an essential subwoofer.

3) You will need some fairly basic woodworking and electrical skills to build one for yourself besides understanding how subwoofers work.

Choosing a material for your enclosure is the next step.

5) Placing your speaker in an unguarded and ungrounded location will cause the speaker to cause damage to nearby electronics.

6) A DIY subwoofer can also be created by buying a subwoofer and amplifier separately and attaching them.

When you decide to take this route, you will find cheap models.

7) As soon as your DIY subwoofer has been assembled, verify that it works properly with a separate amplifier from any other electronics or speakers in your system.

Make sure you don’t get any interference or feedback.

8) Ensure that the subwoofer you build for your DIY system matches the rest of your speakers for maximum performance.

How Do You Repair A Subwoofer? Subwoofer with No Sound

If the speaker cone is torn, you might find a tear there. Here are instructions for repairing your subwoofer at home.

1) Speakers generally contain two parts: woofers and woofer amplifiers.

2) If the woofer works but the amplifier does not, you can consult your local electronic repair shop about fixing and replacing it.

3) blown subwoofers and amplifiers should be tested with an ohmmeter.

4) A blown fuse can indicate that the amplifier is defective or that the amp is not receiving power from the subwoofer’s power supply.

5) If the amp has a problem, like a blown fuse in the subwoofer, you can use an ohmmeter.

6) Two speaker cables attached to your subwoofer’s amplifier are labelled “power” on their backs. To find this speaker wire, connect it to one of the ohm meter’s probes.

To test your subwoofer, touch the other probe to any screws or bolts that are not part of your amplifier.

7) You should not see a reading when you touch the probes together. This is because the amp does not have enough power for the subwoofer to work.

8) If the amp is busted, you might be able to get it repaired or replaced by a local shop.

9) Sometimes, when an amplifier is fine, but power isn’t getting to the subwoofer, the problem may be the outlet itself.

10) If the power speaker cables are damaged, replace them with a new one.

How To Test a Subwoofer

How to test a subwoofer: with a multimeter

Sometimes, you may not notice that the subwoofer is not working properly because it has been blown out. We will often experience distorted sounds when our subwoofers have blown out. Our overall experience will be ruined when we have blown subwoofers.

I will share with you today how you can test the subwoofer to see if there are any issues. In this article, I will go over the most common ways you can test and go through most of them in detail. To learn how to test a subwoofer, please read until the end of this article.

If a subwoofer blows, how do I know?

How To Test a Subwoofer by

A subwoofer is the most important sound system component in terms of sound quality. Therefore, it will be easy for you to detect problems with your subwoofer. The sound output is obvious, and you can see the impact.

You will know your subwoofer has blown when the sound is distorted or breaks between frequencies. A subwoofer that’s blown out can also suffer from a decline in quality.

Despite this, it’s impossible to tell whether the speakers are blown out just by listening to them. To tell if your subwoofer is blown, you will need to test it.

How to test a subwoofer with a multimeter

How To Test a Subwoofer by

You can use a multimeter to check if your subwoofer is blown out. Multimeters are useful for other kinds of work, so you should get one if you don’t own one.

This multimeter is being used to measure the resistance of the voice coil. A subwoofer’s performance can be determined by the volume, which tells you whether or not it is working properly. You can follow the steps below to determine how much resistance is in the voice coils.

  1. First, turn off Your subwoofer, or its power source should be cut. It is impossible to get the correct measurements if you do not do this.
  2. Next, remove all cables and wiring from your subwoofer. Ensure that your subwoofer is completely disconnected from all input and power cables.
  3. After that, remove the enclosure from the subwoofer to allow proper access. After uncovering the woofer, the voice coils can be accessed. It depends on what subwoofer you have.
  4. Attaching your multimeter to the voice coil terminals of the subwoofer will allow you to measure the voice coil. Use the positive end of the multimeter to measure the positive terminal on your voice coil.
  5. Next, you must connect the negative probe to the negative terminal.
  6. In the end, you should see the resistance of your subwoofer by turning on your multimeter, which you should see when you turn it on.

That’s how you test, but what does the outcome look like? There’s no need to worry about that. I’ve got you covered. A multimeter can give you three possible readings.

A multimeter reading that shows no resistance indicates that the voice coils of your subwoofers have already been damaged. Reading can also detect a blown-out voice coil that shifts too much continuously.

It is considered safe if the resistance is greater than 1 ohm. In this case, the subwoofer is not blown out but has some other issues.

How to test subwoofer without Amp

Subwoofers can be tested by listening to their sound. Your subwoofer can be diagnosed much more easily if you have an amp. If you have an amplifier attached, it is possible to hear all the flaws and distortion that result from a blown-out subwoofer.

Testing your subwoofer without an amp is another option if you want more information and aren’t equipped with an amp.

As a result, you can perform a test of your subwoofer without having to connect it to the amp without the need to connect it to the amp at all. You should be able to do this by following the steps below, and you should be fine.

  1. Start by assembling the subwoofer testing tools you will need. An electric tester or multimeter, a 9V battery, and a wire are required for this step.
  2. Connecting the battery to the subwoofer can be done once you have all that. The coil’s positive terminal must be attached to the 9V battery’s positive end with the wire. The negative ends should be done in the same way.
  3. The woofer’s cone should rise after the battery is connected successfully. Once the battery is connected, your subwoofer should rise as soon as it is connected. Disconnecting should result in a drop in the level.
  4. It’s safe to assume the subwoofer is blown out if it doesn’t show any movement.
  5. It is then possible to confirm whether the subwoofer is blown out using a tester or multimeter. The resistance of the subwoofer can be measured using the previous method. It means your woofer is blown out if the reading is not 1 ohm or above.

Your subwoofer can be easily checked to see if it is blown out, needs to be repaired, or has other problems.


By testing a subwoofer yourself, you can save money as it can tell you if there are any problems with the voice coil or its placement without going to a mechanic. When you know what is wrong, you can either replace the parts yourself or hire a professional.

Additionally, you shouldn’t have much trouble testing your subwoofer for any problems since it’s not that difficult. Fixes and repairs, however, should always be left to professionals rather than being attempted by the person. Testing the problems will reveal that they are much more affordable than you expected.


1. How do I know if my subwoofer is blown?

You can identify a blown subwoofer by distorted or interrupted sound output and a decline in sound quality. To confirm, use testing methods such as a multimeter or observing cone movement.

2. How can I test a subwoofer using a multimeter?

To test with a multimeter, disconnect the subwoofer from power and remove its enclosure. Attach the multimeter’s positive and negative probes to the voice coil terminals. A no-resistance reading indicates damage, while a safe reading is above 1 ohm.

3. Can I test a subwoofer without an amplifier?

Yes, you can test a subwoofer without an amp using a 9V battery, wire, and multimeter. Connect the battery’s positive and negative terminals to the coil’s corresponding terminals. If the cone doesn’t move, it may be blown out.

4. What does a rising cone indicate during subwoofer testing?

A rising cone indicates the subwoofer’s functionality when connecting a 9V battery to the subwoofer. If the cone doesn’t rise upon the battery connection, it might be blown or damaged.

5. Why is it important to test a subwoofer myself?

Self-testing a subwoofer saves money and allows you to identify issues like blown voice coils or misplacement. You can then choose to replace parts independently or seek professional repair services for a more affordable solution.
