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.

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.

Conclusion

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.
