Best Competition Subwoofers Buying Guide

Subwoofers are a very popular way to improve your car’s sound system because no matter what your music taste is or the volume you listen to music at, a subwoofer will still increase the sound quality.

With that in mind, it is no shock that the subwoofer market is extremely lucrative and with so many different subwoofers for sale, it can be difficult to identify the perfect one for you.

The list above highlights some of the best subwoofers money can buy you, but ultimately the decision is yours, and we are here to help with this guide packed full of the things you should consider before making a purchase. 

Speaker Dimensions

It is important to consider the dimensions of the subwoofer before you buy as they are usually installed in the trunk of your car.

When you shop for a subwoofer you will notice that they come in a variety of sizes with smaller ones measuring around 6-inches to the larger ones at around 15-inches. Like everything, these products will come with different benefits, for example, smaller subwoofers tend to be easier to fit while larger subwoofers tend to offer a higher SPL range.

Before buying a subwoofer you should consider the sound quality and effect you want to achieve, as different subwoofers will be better to help you achieve this sound. You should also take care when installing subwoofers as any inaccuracies in the installation process may have an effect on the sound that they produce. 

Sound Pressure Levels

One thing you may notice when searching for a competition subwoofer is that most products will not say much about volume in their descriptions.

In normal circumstances, we perceive volume as being directly linked to distance, if we hear something up close it seems a lot louder whereas the further away you move the quieter and softer the sound becomes.

This is because the “volume” we talk about is actually sound waves, and sound waves create pressure within our ears, so the distance increases or decreases the pressure rather than the volume of the sound. 

Due to this professional speakers do not include volume, instead, they offer a sound pressure level (SPL) measurement, which is measured in decibels in the same way we would normally talk about sound.

So when you are looking for a subwoofer it is important to check the SPL measurement to understand the quality you are going to get out of the product. It is vital that you do not purchase a subwoofer with an SPL exceeding 80dB as this is the limit our eardrums can handle before they begin to get damaged. 

Sound Qualities

The goal of subwoofers is to increase the sound quality by increasing the bass, but too much bass can damage the sound quality and so it is all about balance.

To ensure this, you should not only look at the SPL measurement when buying a subwoofer but also the peak power (PP) as this measures pulsing voltage and tells you exactly how high this can go without damaging the sound system.

Achieving your desired sound effect through subwoofers is a very intricate process so it is important to compare the technical specifications to confirm they are compatible with the sound you want to achieve. 


Finally when looking at a subwoofer to buy you should really focus on the product specifications as there is so much to consider that has a huge impact on the sound quality that the subwoofer produces.

For example, the power is very important if you want a booming sound system, frequency is important in identifying how low a subwoofer can play audio at, and sensitivity is also closely linked to power as a more sensitive subwoofer will require less power to produce the same sound as a less sensitive model.

To achieve the exact sound effect you want it is crucial that you take into account all the different technical aspects before making a purchase.

Frequently Asked Questions

What is a subwoofer?

A subwoofer is a large speaker designed to reproduce low-pitched sounds.

Subwoofers affect the sound of an audio clip by altering the bass and making alterations that a regular surround system cannot. 

What is the difference between a woofer and a subwoofer?

The terms subwoofer and woofer have become interchangeably used as there are no major differences between the two terms.

Generally, subwoofers are designed to reproduce low frequency sounds below 30Hz level and woofers tend to produce sounds above this level.

Which subwoofer will sound the loudest?

If you are looking for a subwoofer with the main focus being the level of sound output from it you should consider sensitivity, enclosure type, and the available power as all of these will have an impact on the level of sound the subwoofer gives out.
