The best home subwoofers bring that dynamic and vibrant low-frequency thunder that lays a solid foundation for an immersive music listening experience.

Many people often blast speakers at max volume but their sub fails to produce proper bass or the high-end frequencies overwhelm the low-end frequencies.

Please note that if you are experiencing low subwoofer volume problems, we have a guide on fixing subwoofer low-volume issues.

So how do you get more bass out of your home subwoofer? In this article, we will discuss several ways to do just that!


1. Subwoofer Placement

Finding the right location for your home subwoofer is the first step to ensuring you get the desired amount of bass out of the device.

Take into account how the sub works with the other speakers and how you can make the most out of your small or large room.

Setting up your home sub in a corner can increase the volume, but you need to be careful to avoid the possibility of your listeners finding the output too “boomy”.

Moving it close to the speakers can help you to blend between lower and higher frequencies. But in some cases, this also can cause unwanted resonance.

To get more perfect bass, you can experiment with placement. As you experiment, try as much as possible to:

  • Place it on a side wall, halfway between the rear walls and the front walls.

In addition, subwoofer placement when you have a couch in the room is also important. In particular, there are special considerations for subwoofer placement when your couch is against the wall. Another great option is to place your subwoofer behind the couch. On the other hand, it’s often not a good idea to place your sub under your couch or place your subwoofer behind your TV.

If none of these techniques help you get more bass, start moving the subwoofer. Do this slowly as you listen for the variations in the production of bass.


2. Adjust Your Subwoofer Settings

After finding the ideal spot for your subwoofer, tune it further until you start getting the best sound. Here is the simple procedure you can follow to set it appropriately.

subwoofer crossover and phase settings

Step 1: Adjust the crossover: Adjusting the crossover before playing the subwoofer is the best solution. Set it in the range of 4-Hz to 60 HZ if you have large floor-standing speakers.

Increase the range to between 50HZ and 80 Hz if you are using smaller bookshelf main speakers. For small satellite speakers, you should adjust the crossover in the range of 80HZ to 160Hz.

Step 2: Set Subwoofer Volume to the Desired Level: After setting the crossover, turn on the power. And then adjust the volume until the subwoofers begin to produce more precise bass.

Step 3: Adjust the Phase Control:  A well-adjusted phase control helps compensate for delays between the main speakers and the home subwoofer.

If the control is available, ensure you adjust it as appropriate. Begin with the 0 or normal position. If this enables you to get adequate bass from your listening position, you have achieved your goal.

But if you notice that the sound is still thin, continue adjusting the phase control until you get the kind of bass that you desire.

Step 4: Adjust Frequencies: Setting the stereo audio equalizer can also help you get more bass if it remains thin.

Like with food, both dedicated audiophiles and casual listeners can have certain unique sound preferences. The good news is that the equalizer control empowers you to fine-tune the audios to meet your unique sound needs within a few minutes.


3. Use New Connectors and Cables

As with everything else on this beautiful planet, subwoofer connectors and cables degrade with time. Without a doubt, this can directly impact the quality of the bass that your home subwoofer delivers.

At the same time, tiny, cheaply made wires often reduce the flow of electrical current. This can also starve your sub the amount of power that it requires to produce quality bass.

As a rule, you should inspect your subwoofer cables regularly and replace them whenever necessary.

Unsurprisingly, many people observe this recommendation and use quality cables. But they splice the wires wrongly and end up with undeserved bass without knowing the cause of the problem.

Others also ignore the essence of purchasing quality cable connectors. Without the right connectors, your quality cables will not be able to help you get more bass out of your subwoofer.


4. Choose A Ported Enclosure

Choosing rear or front ported subwoofers can play a major role in increasing the bass that you get. The port reinforces low bass frequencies more than sealed enclosures.

However, this design delivers the best quality sound if the box is a little more spacious.subwoofer ported enclosure

The extra space allows the sub’s cone to have adequate freedom of motion. Vents can also redirect the sound of the cone’s rear and add it to the one emanating from the front of the sub, making the bass much louder.

The above features of ported home subwoofers make them incredibly efficient. With increased efficiency comes the reduction of the power juice that it requires to produce more bass consistently.

5. Fill the Box with Polyester Fiber Stuffing

Filling your ported enclosure with polyester fiber stuffing like polyfill can also increase the bass quality that you get out of your home sub.

Fill the Box with Polyester Fiber Stuffing polyfill


As we have said, a ported subwoofer performs best in a large box. If your enclosure is small, you can make the sub think that it is large enough by filling it with this material.

I know you may be saying that this tip sounds counterintuitive. Possibly, you are also asking what filling the box with polyester fiber stuffing has to do with the bass of your home sub.

Well, the fact of life is that the stuffing slows down sound waves inside subwoofers. As this happens, the sub gets fooled that the box is large and improves the amount and quality of bass that it produces.

For the best bass quality, however, you should use between one and one-and-a-half pounds of polyester fiber per cubic foot of your ported subwoofer’s volume.


6. Minimize Electrical Impedance

Electrical impedance refers to the resistance that subwoofers face in converting electrical signals into audio.

A high level of resistance may reduce the device’s ability to produce quality bass.

To mitigate this problem, you should match the specifications of your subs and audio system. Moreover, you need to ensure that the coils and magnets are in the best working condition.


7. Use Quality Audio Files

The quality of the music files that you play can also affect the bass that your subwoofer emits.

If your files have been over-compressed, they have low quality and will likely not produce the bass you yearn for.

The compression always leads to the loss of low-frequency details that your subwoofer requires to deliver the kind of listening experience that best serves you.

If you like streaming online content, you also better watch out for the option that allows you to set the appropriate bass and the overall sound quality.

Alternatively, you can stick to the streaming services that provide higher resolution and get more bass out of your home subwoofer whenever you want.

Two of the best audio files for high-quality bass output are FLAC and AIFF. You can also use lossless MP4 or any other lossless audio files.


8. Run Multiple Subs

There is another never-ending question that we should address here. Some people want to know whether two subwoofers guarantee better bass than one.Run Multiple Subwoofers

The answer is ‘yes.’ But for you to realize your goal, it is recommended that the subs should be of the same model and brand.

Due to the subs’ combined bass output, they will yield a much better base if you above these conditions and supply adequate power.


9. Feed Subs Enough Electric Power

Assuming you have done everything required to minimize electrical impedance, you cannot have an impressive listening experience if you are using an unreliable source of power.

You need to have enough power given that bass notes need more electric energy than higher-level frequencies.

If you underpower your home theater system under any circumstances, you will not get proper bass.

In this case, your sub will turn up a distorting signal in an attempt to get bass volume. In fact, your under-powered subwoofer will likely get damaged.


10. Add Sound Deadening Material

Adding sound-deadening materials, also known as damping, helps to get rid of vibrations and noise. These interruptive forces compete with music and distort your listening experience.Sound Dampening Materials to subwoofer acoustic foam

Minimize the risk by lining up the walls with a layer of acoustic foam or any other sound-deadening material.

The materials will absorb sound reflections and cut the standing waves. If you can remember, we said that you could use a material like polyfill to improve bass by making the box seem ‘larger’ as the waves move through.

However, in this case, we are damping to deal with the reflections, which are another major enemy of quality bass.


11. Invest In An Amplifier

Firstly, if you cannot afford an amplifier, that is fine. There are many ways to improve bass output without an amplifier.

However, if you crave more bass out of your subwoofer and your budget allows you to invest in a high-quality amplifier, you can make your subwoofer blast louder with one of the best amps out there.

But it does not end with buying an expensive amplifier. You must be able to set it up appropriately. Follow this simple process to do so.

  • Consider Placement

You need to choose the best amp rack based on the material used to make it. The acoustic properties of the material the amp is placed on will have a direct impact on the amp’s efficiency, and that can reduce its ability to amplify the sound that your home subwoofer produces.

For example, if you go for glass shelves, your sub is likely to sound forward. But your wooden support is highly expected to bring about a louder, more rounded, and warmer balance.

Moreover, you should think about the spacing between the wall and the amp. A few inches of breathing space can ensure that the amp maintains the right temperature, determining the level of efficiency.

  • Opt for Bi-Amping

Bi-amping allows you to use at least two power amplifiers. This allows each amplifier to handle various channels or frequencies.

By doing this, you reduce the workload of your amp. In turn, it operates efficiently and helps the subwoofer to produce better-quality bass.

  • Proper Connections

Proper amplifier connections will also determine whether the amp will help your home subwoofer to produce louder bass.

Before placing the back to the wall, take your time to check the amplifier’s rear panel to find the available options for connecting different sources. Connect via the RCA or LFE inputs.

  • Upgrade

In the same way, you can upgrade your subwoofer, your amp may require upgrading too. Upgrading does not necessarily mean doing away with the old amplifier.

One way you can handle this is by using an amp with pre-amp outputs solely as a pre-amp. You then pass on the other duties to another amplifier. At the same time, you can choose to upgrade your amp’s main cable.


12. Add a Subwoofer Horn

A subwoofer horn can increase the efficiency of your sub. The simplest way to identify it is to look for a flared tube and attach it to the sub’s output.

The horn will serve to direct the sound to the right listening location, increasing your chances of getting a quality base despite the relatively long distance between you and the subs. The increased efficiency will also help you to achieve better power output and power transfer.

However, you should avoid the possibility of the air’s non-linear nature causing the horns to distort the audio.

This often occurs when much power is put through. Also, too much wind noise can come through the horns and cause distortions as the air pushes against the horn’s surface. You need to test this technique, and whether it works for you before you make the decision.


13. Replace the Subwoofer

I believe we all agree that subs are not created equal. Some were not designed with the needs of the end user in mind. There are instances when the best way to increase the bass output is to invest in a quality subwoofer.

In some instances, you can modify your sub significantly to be able to improve its performance. If you are in such a scenario and do not want to dirty your hands by trying to modify it, the only viable option could be to replace it.

Remember that when it comes to subwoofers, size also matters. That means if you have a 6.5-inch sub and are serious about getting the type of bass that guarantees you a kind of bone-shaking impact, you have no choice. No technique can give the experience if you do not replace the small with a bigger subwoofer.

Let’s take an example, if you compare 10″ vs 12″ subwoofers, you will find that 12″ subs will deliver more bass. 

That is not to imply that small subwoofers cannot offer you impressive performance. The truth is that this boils down to your preference. If you are okay with smaller subs, you can still use the other tips in this guide to boost your listening experience.

How Do I Make Subwoofer Louder Without Amplifier?

Amplifiers are expensive, and it’s wise to take steps to make your subs louder before deciding to obtain an amplifier.

Step 1: Place your sub in a corner, as this can provide up to six decibels of bass boost without amplification.

Step 2: Make sure the subwoofer is in phase with the rest of the system without any variance. Play some bass-heavy music and adjust the phase switch until you hear the loudest bass.

Step 3: Place the subwoofer in an asymmetrical position relative to room boundaries will result in louder bass output and the smoothest overall response.

Step 4: Fine-tune the subwoofer crossover controls to get louder bass than just randomly setting it or leaving it at the default factory settings.
