How To Make Subwoofer Louder? Top Full Guide 2021

In this article, Hooke Audio will teach you how to make subwoofer louder, hopefully resulting in a more satisfying listening experience. Subwoofers are one of the most important components of an audio system because they are responsible for converting electrical energy to mechanical energy. They are generally large because they generate intense sound waves at lower frequencies. However, their size also makes them loud and sometimes really annoying.

Keep going on to get more useful information for your sound system.

What Makes A Subwoofer Loud?

Power Handling

Each Subwoofer is rated at a certain wattage, which the company declares during its release. Your subwoofer’s power will determine how much power your audio system can handle. Subwoofers’ ability to produce volume and loudness is crucial.

Subwoofer manufacturers usually use two power figures:

  • Nominal power (RMS): Can handle a certain amount of power for a long period of time without being hurt.
  • Peak power: The maximum amount of energy that can be held for a brief period without causing damage.

Subwoofer Size

Which subwoofer type is best for loud sound? This is a complex question. The size of a subwoofer does not determine its ability. A subwoofer’s power handling, sensitivity, and music file type are all important factors that make it louder.

Many advantages can be derived from car speakers of a prominent size. A large subwoofer can move more air than a smaller one. They can produce high-quality sound and loudness. Subs need to be larger in order to make them louder.

A sub will produce less sound if it does not have enough power, even though it may be smaller or more important. To handle greater capacity, the manufacturer offers two factors (RMS and peak power).


A sub’s sensitivity is also crucial. Sub’s sensitivity can be used to measure the input power and output of your device. It is usually measured in decibels. A higher sensitivity equals better output sound. The majority of speakers have sensitivity levels between 87 and 88 dB.

It produces poor sound output if it has a sensitivity below 84. A subwoofer output is best when it exceeds 90. Make sure you know which subwoofers came with what sensitivity.

Type of enclosure

The sub box is another important part. It enhances the subwoofer’s volume. The number of types of ported enclosures you have will greatly affect the speaker’s sound quality.

To produce many sounds, it is best to use a cone that’s suitable and a box that’s well-built. An inadequate section can’t increase bass quality. You should also be mindful of the ported boxes.

How To Make Subwoofer Louder

1. Place Subwoofers Correctly

Place Subwoofers Correctly

It’s amazing how much a subwoofer’s position can make a big difference in the sound quality. Your subwoofer’s position can greatly influence the bass volume in the room. Subwoofer and speaker placement are both important.

The subwoofer is usually placed in the middle of the home theater setup, or in the corner. We recommend that the subwoofer be placed in the corner. This allows you to get up to six decibels of bass boost without the need for a subwoofer amplifier.

Be sure to keep at least 3 inches between the walls and your sub-woofer. If you’re using a rear-ported sub, this distance requirement is even more critical.

You can also move the subwoofer around in the room. This is the most important tip. It is important to not place the subwoofer at the same distance as two walls. A subwoofer placed in a different position to the wall will produce louder bass.

Here are some speaker placements that will work in small spaces. A good idea is to put your subwoofer behind the couch. Place your subwoofer underneath the couch.

2. Tune Your Subwoofer Properly

To make subwoofers blast louder and clearer, many people increase the volume on their sound system. A substandard system can cause a significant, low-frequency increase to strain the network. To confirm if you’re getting a louder, more precise sound, tune the unit controls and listen to it.

3. Adjust Phase Setting and Crossover

Adjust Phase Setting and Crossover

A crossover, low-pass filter, and phase sets are all necessary to boost your subwoofer’s powerful bass. This adjustment is crucial for increasing bass. The sub should be in phase to the entire sound system. The subwoofer comes with a single-phase switch and a variable dial.

You can adjust the setting until you achieve the desired bass level. These dials can be adjusted to a constant position or, in certain cases, to a 180-degree position. Also, check your crossover settings. It works in conjunction with phase to provide the best quality.

Incorrect crossover settings are the main cause of unhealthy competition in bass frequencies between subwoofers and main speakers.

They try to cancel one another, which can cause muddy or distortion of sound. You can prevent competition by setting the crossover settings correctly and getting better sound quality without an amplifier.

Take your time, play bass-heavy music and adjust the phase switch until the bass is the strongest.

4. Use high-quality audio files

Don’t forget to consider the quality of your audio files and the quality of the subwoofers that can emit them.

Many musicians in the music industry are currently trying to reduce their files by using compression.

The compression causes car audio to lose low-frequency and high-frequency information. This can lead to music that is not loud enough or exciting.

You may not notice the reduced quality of compressed music if you listen to it through headphones or earbuds. Remember that the higher the bitrate, the better quality the music file.

Lossless audio formats are the best for sound quality. FLAC and AIFF are two examples of such formats.

You can also lose the quality of your music streaming. You might consider using apps with a higher resolution. Also, make sure that the sound quality settings of your music app are high quality.

5. Reduce Electrical Impedance

A subwoofer that is efficient should be capable of converting electric energy into sound with minimal limitations. The electrical impedance is the resistance that a subwoofer must face to perform this function. A subwoofer with a high impedance will have less ability to transform electric energy into car audio.

You can ensure that your subwoofer is in top shape and has minimal electrical impedance by ensuring its coils and magnets are operational.

You should also ensure that the circuitry controlling your subwoofer is in top shape.

An electrician will be needed to inspect these components and replace any damaged ones.

6. Add Sound Dampening Materials

Add Sound Dampening Materials

Low-sounding subwoofers could be due to vibrations coming from the enclosure.

You can reduce the vibrations by using insulating or dampening material. This technique is used by many car owners to increase the volume of their car subwoofers. To reduce vibrations, dampen the floor. You can also reduce vibrations by dampening the floor. Noise levels and an increase in sound Accuracy with ease

Creative created a cute style statement using a 7-inch cubical enclosure. Experts will tell them that Cube is the worst design due to its parallel surfaces and internal reflections. The MDF was also bare and glossy giving the Cube a boomy effect that can be seen at 80100Hz.

A layer of Acoustic Foam will be used. This foam cuts through standing waves and absorbs reflections. This foam gives you a more balanced bass response and less distortion. Because of space constraints, I could only do 2 sides. You can do all sides of your box is bigger. This is a good use of hot glue.

7. Replace the cables

Your entire home theater system, like everything else, requires proper cables in order to work properly.

It is important to replace the cable from time to again. Old wires can cause problems with electrical signaling in your car stereo system and lead to poor sound quality. Buy Quality made cables in a suitable size. They allow for the free flow of electricity. This means that speakers won’t be starved of enough power to function optimally.

If your cables are damaged or worn, replace them immediately.

8. You can isolate your subwoofer from the floor

isolate your subwoofer from the floor

Subwoofers generate a lot of vibrations. As many people place their subs on the floor, a lot of those vibrations will travel through the floors and take with them a lot of the sub’s output.

Isolate your subwoofer from the floor is an easy solution.

9. Get a better heatsink

Electronics are at the mercy of heat. Subwoofer circuitry, in particular, can produce a lot of heat that can have a significant impact on performance.

Subwoofers are equipped with amplifiers that amplify the signal they receive. These amps can produce a lot of heat.

You can speed up heat dissipation by increasing the heatsinks. You can find an additional heatsink anywhere.

If you are a DIY enthusiast, these heatsinks can be found in many electronic items such as old amplifiers and computers, DVD players, power supplies, and other electronics. A heatsink can also be purchased at your local department shop.

You can replace a heatsink that is larger than the one on the subwoofer circuit board, or the back of your sub, with a larger heatsink.

You would only need to apply a thin coating of the heatsink compound to the contact surfaces. Then, glue the heatsink sides down.

10. If your Subwoofer is in a sealed enclosure or custom box

There are several steps you can take to increase the volume of your subwoofer if it is housed in a DIY sub-box. These are the steps to follow:

1. Get a Custom-Ported Subwoofer Box

The subwoofer box’s type is very important. However, the enclosure has the greatest influence on how loud and deep the subwoofer will sound.

A custom-ported box is a great way for subwoofer performance to be greatly improved.

You can make your sub’s performance much better by porting it instead of sealing it completely. You should tune the port to the 50Hz region for loud bass. For deep bass, you can also see our sub-box design.

2. Polyfill the Subwoofer Box

You will generally find that sealed enclosures are smaller than their ported counterparts.

Polyfill is one of the best and easiest ways to increase the bass performance in an enclosure. It will produce a richer and deeper bass sound.

What is the secret to this?

The idea behind the polyfill is to slow down the sound waves as they travel through the box. This will make the box seem larger in terms of the sound waves. This allows for deeper bass extension.

Here are some ways to do it.

Start by adding a thick layer to the bottom of your sub-box. As you work up, start to add thinner layers.

Don’t pack it too tightly or you risk the bass waves leaking through. Add a cotton gauze to the top of the box once you have reached the top. The polyfill fibers may eject from the port if you don’t do this. It can be glued down, but only use simple glue.

For an even more impressive effect, make sure to seal your sub box tight.

3. Select A Box Made With Sturdier Material

It is important to choose the right material for your subwoofer. Many people replace the subwoofer enclosure with a different material. This is why it is important to ensure that the enclosure is strong.

This improvement is great for sealed enclosures, but it can be quite significant for ported enclosures. Because sealed enclosures can often cause sealed air to circulate around the sub box, causing wood fibers to expand. It can be very inefficient over time. You can make a sub-box that is sealed using MDF or fiberglass.


The quality of your subwoofer’s sound may not be up to par. Luckily, we’ve just told you a few different ways to make it louder and to put out a louder, deeper bass sound. Hope you can apply it in your work and can be successful.
