Some people may experience sound imbalance when listening to music because of various factors, such as faulty equipment or installation, the room they are in, and the way they are using their subwoofer. However, this is not an issue that can be taken lightly since it will lead to high levels of frustration. In this article, Hooke Audio will answer a common question of why does my subwoofer sound weak? and how to fix this issue.

Why Does My Subwoofer Sound Weak?

Minimum Low – Frequency Sound

Inexperienced users often expect to hear the bass and are disappointed when they don’t. The sub does not reproduce low-frequency sounds like drums or bass guitar.

The sub will not turn on if these low-frequency sounds do not exist. Make sure that you are not playing media with low-frequency sounds such as rumbles and heavy bass before you start to panic. You may need to look into other possible causes only after this.

Lowered Bass Woofer Level

A second reason could be that the volume of your bass woofer isn’t adjusted properly. Check the volume and if it is too low, adjust it to your preferred loudness.

Users often ignore the bass level because it is adjusted separately from other speakers.

The soundbar remotes of most models have a button called a woofer that can be used to change the bass sound. You should check the user manual if your remote doesn’t have one.

Incorrect Speakers Setting

The subwoofer, a group of woofers, functions best when the audio configuration is used. You need to have all components of the configuration synchronized in order to achieve this.

Different low frequencies are produced by the subwoofer and full-range speakers. It is important to set up your speakers correctly before you use your audio system.

Your main speakers should have the same frequency settings as your subwoofer.

Poor Room Acoustics

Experts in audio-video indicate that room acoustics is of paramount importance for any audio-video system.

Professionals point out that many studios are not built to nasty standing wave issues, something even the best subwoofers cannot overcome.

Your sub’s sound quality can be affected by poor acoustics. Before you blame your sub for your soft sound, ensure that your room has good acoustics.

Poor Sources Configuration

Subwoofers can sometimes cause problems in studios. To determine if the problem is caused by the subwoofer itself, you can simply check the microphone and other audio sources.

Connect your subwoofer directly to an audio source such as an iPod. If you hear a good sound, then it is possible that your source configuration is not working properly.

Subwoofer with Underpowered

It is generally safe to underpower your subwoofer. Subwoofers that are not given enough power will produce weak sounds.

You must also be careful not over-power the amplifier. A clipped signal can cause serious damage to your subwoofer if the amplifier is overloaded.

Incorrect Amplifier Size

This could be a sign that your subwoofer sounds good at low playback levels, but the sound weakens when you increase the volume. The amplifier you have is too small to be of any use and should be replaced with one that has greater capabilities.

You may need more than one amplifier depending on the size and complexity of your system. One amplifier channel per subwoofer is the best configuration.

Motor Failure

When your subwoofer sounds weak, a more severe problem can be a motor fault. After you have determined the cause of the subwoofer’s weak sound, check that the motor is still functioning properly.

Motor problems can be caused by a blown fuse or battery. This could cause a problem with the sound quality.

A Mis-polarized Subwoofer In An Array

Subwoofers must be in the correct polarity when working together in a sound system. A subwoofer that does not have the correct polarity will result in a lower sound pressure level (SPL). Subs with insufficient SPL can cause subs to sound weaker. Professionals should conduct polarity testing on all loudspeakers after setting up a sound system.

Are Subs Wired Out-of-phase?

Woofers Wired Out-of-phase

You should ensure that multiple subwoofers are not wired out-of-phase if they have different bass levels. A subwoofer wired “Out Of Phase” is the most obvious sign. The subwoofer’s positive (+) terminal is connected to the amplifier’s negative (+) terminal.

If there are two subwoofers in an enclosure, with each woofer facing the same direction, and one is wired out-of-phase, the subwoofer wired out-of-phase moves in the opposite direction. It’s like one sub pulling and the other pushing.

If it is caught soon after installation, it may not cause any damage. It can cause damage at high power levels, as the subwoofers move in different directions. Additionally, the enclosure pressure can allow subwoofers’ to move too much or too little.

Too much cone movement can lead to the subwoofer moving outside of its linearity. Conversely, a too little movement can stop the coils from cooling.

This problem can be easily fixed by connecting your subwoofer wire to your amplifier. Make sure that the (+) terminal is connected to your amplifier’s positive (+) terminal, and that your subwoofer (-) is connected to the amplifier negative (-). This type of wiring is commonly known as “Wiring in Phase“, and it is the most common.

How Do I Make My Subwoofer Sound Better?

You can do many things to improve the sound quality of your subwoofer.

There are many ways to alter the sound the subwoofer makes when the volume is low. These are some ways to make your subwoofer more enjoyable:

Step 1: Add a Filter To Your Subwoofer

Subwoofers often have an electrical filter. These filters are combined with the resonance filter in your amplifier to make the sound of the subwoofer be fantastic at low volumes but will cause distortion at higher volumes.

You can change this by adding a foil or paper size foil to the subwoofer.

Step 2: Change The Spider Type in Your Subwoofer

A tweeter is something most people know, but a spider is a small cone that sits in front of a woofer. A spider can be changed to create a completely new sound.

Step 3: Add a Phase Switcher to Your Subwoofer

This is something that many people don’t know, but phase shifters sound exactly like what they sound.

These can be added to your subwoofer, transforming it into a bass booster. This is a great way to get rid of background noises that you hear on the radio.

Step 4: Don’t Overpay For Your Subwoofer

Subwoofers produce lots of basses. To get the best sound, you may need to lower the volume.

This will reduce the sound quality of the subwoofer’s low-frequency bass.

Step 5: Upgrade Your Subwoofer

To make subwoofers sound better, most need a new voice coil. You will also receive a new subwoofer box, speaker wires, and a sub box when you upgrade your subwoofer.

How Do You Test A Subwoofer Speaker?

You should inspect your subwoofer regularly, no matter if you have the top wireless TV speakers and the best Karaoke speakers. It is important to check if the subwoofer emits clear notes or sounds fuzzy/hazy. You should also check the low-frequency range of your subwoofer as different models transmit different frequencies. The subwoofer won’t play low-frequency sounds in such cases, even if it’s in excellent working order.

It’s a sign that your subwoofer is reaching its limits. This happens when the volume is increased to maximum and the subwoofer is played loud. Clarity should be restored by lowering the volume.

A blown subwoofer will be caused by leaving the subwoofer volume knob at its maximum length. This can cause internal damage. It can also cause soft sound and a decrease in output.

You can play different audio tracks (music and movies, shows, etc.). To test the subwoofer’s sound quality. To get the perfect volume, adjust the volume control until it is at the right level. Do not touch, push, or hit your subwoofer. These units can be damaged and may stop functioning if they are not properly maintained.

A multimeter is another way to check the subwoofer’s sound quality and to determine why it is not working properly. A multimeter will quickly tell you if your subwoofer has failed, is malfunctioning, or is in perfect working order. A subwoofer volume may be low in rooms with poor acoustics.

How to Get More Bass Out of Your Home Subwoofer?

Even with a supposedly bad subwoofer, you can still create a sound system that sounds great.

To amplify bass, place the subwoofer in a corner of the room. To adjust the room’s acoustics, place it between the main speakers.

You can change the crossover frequency of the subwoofer by identifying its lowest range. To make the subwoofer hit harder, adjust the frequency settings.

Adjust the bass settings within the equalizer. There is no single solution. Most subwoofers will need to be adjusted based on the input type.

Begin with the lowest volume, and increase it gradually until the subwoofer makes the most sound. Bass boost can be achieved by turning up the volume.

For connections, use quality cables. To prevent fluctuations in power supply, invest in a voltage protector. A second subwoofer can be added for improved bass management.


Does The Weak Sound Mean that My Subwoofer is Bad?

Your subwoofer may not be producing weak sound, but it does not necessarily indicate that it is defective. You may need to adjust the volume, improve your acoustics, or make some other adjustments. If your subwoofer is still weak after examining the possible causes, you will need to have it professionally diagnosed. This diagnosis will help determine the best course of action.

How Can I Make My Subwoofer Sound Better?

You can magnify the sub’s sound in many ways. Fanciers often add phase shifters or filter to their subwoofers. Fanciers also modify the cone type at the front of the subwoofer (spider) but are careful to not overcompensate. You should also upgrade your subwoofer frequently. They will sound better if they have a new subwoofer enclosure or voice coil.

How Can I Make My Subwoofer Hit Harder?

Turn the volume knob on your sub to zero, and then play some music with moderate bass. This will make it hit harder. Turn the volume knob on the head unit to maximum, and then increase the gain until your subwoofer begins to sway. To eliminate any distortion, reduce the gain. If your subwoofer has been properly installed and configured, this method should work without any problems.


There are a lot of factors impacting your subwoofer quality. Consider carefully to find out what’s wrong with your device and try to fix it to bring the best sound quality.
