Last Updated on November 6, 2022 by Devon

If your subwoofer is distorting, it can be really frustrating. But don’t worry – it’s a common issue and one that can be easily fixed and you may want to know how to fix the issue, or you may not even know where to start. 

That’s why we have created this blog to help the people who are facing that issue. In this article, we’ll outline how to fix subwoofer distortion and some of the most common causes of subwoofer distortion and provide tips on how to remedy them.

So, whether you’re dealing with noise from your amplifier or poor sound quality from your speakers, read on for helpful advice.

What is subwoofer distortion and how can you tell if your subwoofer is distorted?

Subwoofer distortion is a type of audio distortion that can occur when the subwoofer is overexerted. This can happen if the subwoofer is turned up too loud, or if it’s trying to reproduce frequencies that are too high for it to handle. When distortion occurs, the sound coming from the subwoofer will be “muddy” and lack clarity.

Additionally, you may notice that the bass sounds “fuzzy” or “bloated.” If you think your subwoofer is distorted, try turning down the volume or adjusting the EQ settings. If the distortion persists, it’s possible that the subwoofer itself is damaged and will need to be replaced.

How to Fix Subwoofer Distortion – Different options

How to Fix Subwoofer Distortion guide

If your subwoofer is causing sound distortion, use one or more of the following methods to fix it:

1. Choose a lower crossover frequency

The frequency at which your subwoofer hands off low-frequency sounds to the main speaker can have a big impact on how it performs. If you set this too high, then certain tones will be missed and distorted because they’re outside of what’s considered “normal.”

If you want to fix this, then just set your subwoofer’s crossover frequency lower. For most people with average-sized rooms and smallish bass bins in their cars or trucks (or whatever), an ideal setting would be between 80 – 120 Hz

2. Reduce the volume setting to a lower level

The best way to avoid this problem is by making sure that your subwoofer can handle the volume. If you’re not sure if it will work, turn down some of those loud sounds before they cause distortion!

You may have to turn down the volume of your subwoofer. Start with it at a low setting and gradually increase until you find that perfect spot where sound seems neither too soft nor loud, but just right!

3. Use a Subwoofer with a larger diameter

If you’re still experiencing subwoofer distortion, it may be time to upgrade your speakers. A larger speaker can handle higher volumes without distorting the sound and will ultimately provide better performance in all areas of audio comprehension—not just bass frequencies!

4. Setting Up Amp Gains Correctly

You can’t underestimate the power of getting an amp that is capable enough for your subwoofer. When setting up frequencies, make sure to check how much gain (or volume) each specific model requires in order to avoid any distortion from occurring on either side!

The amp gains should be set to a lower setting. Start with the volume low and gradually increase it until you find that perfect balance between bass response and clarity for your ears!

5. To minimize distortion, use equalization.

The process of equalizing a sound can serve as an effective way to reduce distortion. It’s also worth considering if you want more clarity in your audio output, but it will take some time and effort on behalf o get there!

The most common way to equalize sound is with a graphic equalizer. This device lets you adjust the levels of specific frequencies, which can help reduce subwoofer distortion and make your car’s interior more comfortable for listeners who are sitting near or behind it!

6. Reduce Distortion with Sound Damping

If you want to reduce the amount of distortion from your subwoofer, try using sound damping. Sound-damping material can be placed on top or near where a speaker is installed and will absorb vibrations so they don’t make their way into it!

Some people have found that the only way to fix their subwoofer’s distortion problem is by buying a new one. This can be expensive, but it may work for you if nothing else does!

7. Use a Subwoofer Isolation Pad

A special type of foam can help you solve the problem with your bass. This is an isolation pad designed to absorb vibrations and prevent them from reaching speakers, so it’s best used in conjunction with one!

The bass from your subwoofer sounds garbled and distorted? It may be because of vibrations. This can happen when you don’t cure the problem by fixing it quickly, but there are ways to reduce this distortion without having any permanent damage done!

8. Use a Subwoofer Enclosure

You can also try using a subwoofer enclosure to get rid of the distortion. A box that houses your speakers, will stop them from vibrating and thereby reducing any unwanted noise or harshness in sound waves!

9. Replace the Subwoofer

If you are still experiencing subwoofer distortion after replacing your speaker, it is time for a new one. A better chance at clear sound without any static or buzzing will be experienced with the brand-new model instead of an old unit that has seen its day come and go already

10. Upgrade Your Sound System

Installing a new sound system may be your best option when the old one doesn’t seem to fix any problems with clarity. You’ll want this for both yourself and those who come over so they can enjoy their time in comfortable conditions!

There are many ways to reduce subwoofer distortion, but if you’re still having problems with it then there may be an audio expert who can help. They will point out what’s causing the problem and suggest solutions for reducing or removing them from your system so that they don’t bother anyone else!

What causes subwoofer distortion?

distorting subwoofer

Subwoofers are often referred to as “distortion machines” because their high-frequency response can cause distortion when a strong signal is sent to them. Distortion can occur in two ways: frequency response distortion or amplitude response distortion.

Frequency response distortion results from nonlinearities in the compression circuits. Amplitude response distortion results from a low sound level, while frequency response distortion occurs when the subwoofer is unable to reproduce the original waveform and the low frequencies are compressed. Both these types of distortion can lead to poor sound quality.

1. The subwoofer is moved away from a wall

When the cabinet moves further away from the wall, its volume decreases. The lower the volume of the speaker, the less the bass can be heard, and the more the speaker distorts. This is known as low-frequency roll off (LFR).

2. Subwoofer sounds distorted at low volume

When you turn the volume up to full, it distorts the sound coming out of the woofers. There is an amplifier called a “compressor” that controls how much gain there is in the woofers before they are amplified by the woofer box’s power amp stage.

You can adjust this compressor’s parameters (gain, threshold, and release) to make the bass softer and tighter. When the bass level is increased, it distorts the sound coming out of the woofers. This is called low-frequency roll off (LFR). The woofers usually distort when the subwoofer is moved too far away from the wall.

3. Voice Coil Voltage 

This is caused by a non-linear compression system. When you drive a subwoofer, the power level that the speaker is receiving is not the same as the power level that the amplifier is giving to it.

This means that the speaker’s voice coil does not have the same amount of voltage that it would get if it were driven directly by a 120-volt AC current source. The voice coil is usually a small wire that is wound around a bobbin.

This bobbin contains the voice coil and the magnets. It has a magnet wire attached to it. The coil is attached to a cone that vibrates when a force is applied to it.

4. When Bass hits the driver

If you have a subwoofer, when the bass hits the driver, it will vibrate the driver back and forth. This vibration causes a harmonic effect that causes distortion to occur at certain frequencies. It is similar to hitting a tuning fork with a hammer.

4. Small Speaker Size

If the speakers are too small for the space, they won’t be able to produce enough bass to cover the entire room and can distort when pushed hard. The size of the room will affect the ideal speaker size for it. When buying a speaker, keep this in mind.

How to adjust the settings on your subwoofer for optimal sound quality:

If you’re a music lover, you know that having great sound quality is important. And if you have a subwoofer, you know that it can sometimes produce distorted sound. But don’t worry, there are ways to fix this! With a few simple steps, you can adjust the settings on your subwoofer so that it sounds its best.

First, take a look at the volume levels on your subwoofer and receiver. If the volume is set too high, it can cause distortion. So make sure that the volume is turned down to a comfortable level.

Next, check the crossover frequency setting on your subwoofer. This is the frequency at which the subwoofer starts to reproduce sound. If it’s set too low, it can cause distortion. So make sure that the crossover frequency is set to a higher level.

Finally, if you’re still having trouble with distorted sound, try moving the subwoofer to a different location in the room. Sometimes, certain locations can cause sound to bounce around and create distortion. So experiment with different locations until you find one that sounds best.

Tips for getting the most out of your subwoofer and avoiding distortion?

  1. Check your subwoofer’s owner’s manual to make sure you’re using the right size and type of amplifier.
  2. Make sure your subwoofer is getting enough power. If it’s not, the sound will be distorted.
  3. Turn down the bass on your stereo or home theater receiver. This will help prevent your subwoofer from distorting the sound.
  4. If you’re using a powered subwoofer, turn down the volume on the subwoofer itself.
  5. Move your subwoofer to a different location in the room. Distortion can be caused by the subwoofer being too close to a wall or corner.
  6. Try a different type of speaker cable. Subwoofer cables are usually thicker and have heavier gauge wire than regular speaker cables.
  7. If you’re still having problems, bring your subwoofer to a qualified audio/video technician for help.
