Everything There Is to Know About Subwoofers (How to Choose)

Are you interested in setting up subwoofers or want to learn more about what makes them tick? If so, you’re in the right place. 

In this post, you’ll be able to learn more about what exactly subwoofers are, the different types, all the main features, as well as the best ways to go about installing them for different purposes. 

The deep bass sounds that shake the walls when you’re at the movies or at concerts are produced by subwoofers. If you wanted to create the same kind of experience for yourself at home or in the vehicle, you may want to learn everything there is to know about subwoofers before you get started. 

What Are Subwoofers?

Let’s start with the basics of what subwoofers are. They work similarly to speakers in that they produce sounds. However, the key difference is the type of sound that they create. 

Regular speakers are awesome for producing mid and high range sounds. However, when it comes to that booming sound, a subwoofer is required. 

This is because subwoofers work to produce low frequency sounds. These are the sounds that are much deeper than the sounds produced by regular speakers. 

As a result, you’re able to hear new sounds that you may not have heard before without a subwoofer because it exposes the lower frequencies. 

If you’ve been missing that wall shaking sound effect at home that you usually get at the movie theater, it’s because you need to include a subwoofer into your sound system.

Different Kinds of Subwoofers

If you’ve been looking for subwoofers, you will have seen that there’s a range of different types available. To gain a better understanding of these various subs and what makes them different from one another, take a look below. 


Subwoofers that are powered are among the most popular options because they’re a lot easier to set up. This is because these subs come with an amplifier already built-in to the cabinet. 

Therefore, you won’t have to spend time on trying to find an amplifier that works well with your subwoofer. The amplifiers work to power the sub and produce the sound. 

When you’re integrating powered subwoofers, you simply need to plug it into an AC power source, plug in all the correct cables, connect it to a receiver, and you’re good to go. 


Passive subwoofers are ones that don’t come with an amplifier already available. Therefore, you have to find the amplifier elsewhere before you can start using the subwoofer. 

Without an amp, your sub will only be able to work as well as your standard speakers. If you’re new to subwoofers, using passive subs can make the process more difficult. 

This is due to the fact that you need to find an amp that fits well with your subwoofer. Passive subwoofers need external amps to power them and produce those loud deep bass sounds. 

Other Important Features To Consider

Before you go ahead and decide on choosing a subwoofer for your vehicle (underseat subwoofer) or home theater system, there are some key factors that you’ll want to know more about. 

We’re about to go through what these main features are in this section. 

Down & Front-Firing

The two types of subwoofers available are either front or down-firing. So, what’s the difference between them?

Well, down-firing subwoofers have a speaker system that has been designed in a way so that the sound goes down towards the floor. As a result, it’s able to spread across larger rooms easier. 

The front-firing subwoofers include speakers that have been mounted in a way that enables the sound to travel directly forwards or to the side. These subwoofers are best if you’ve created a system where the sound can travel directly forwards towards where you’re sitting. 

However, the down-firing ports are better if you’re looking to set up the sub in a corner of the room where it’s more out of the way. 

Port Types

Not all subwoofers come with ports. The ones that do use them to allow more air to flow throughout the interior of the cabinet. As a result, it’s able to produce louder bass sounds which makes them best if you’re setting up a subwoofer in a larger room. 

There are also sealed enclosures that don’t have any ports to let air through. These ones are recommended for people who are integrating subwoofers into smaller rooms. 

This is because the sound that’s produced is a lot tighter and wouldn’t be able to travel across bigger rooms. They work more efficiently and can create sounds that are more accurate. 


If you’ve been researching subwoofers, you may have noticed information that deals with crossovers. 

This is a system that directs the various frequencies to the right places. For example, the higher and mid range frequencies are routed towards the other speakers in your system as they’re able to deal with those sounds better. 

However, the low frequency sounds are sent to the subwoofer for it to produce the deeper bass sounds with more accuracy and volume. 


The low frequency sounds that subwoofers are capable of producing are not directional. That means that you’re not able to tell exactly where the sound is traveling to as you’re listening to it. 

This is one of the elements of a subwoofer that make it so versatile in terms of where you can place it in a room. If you were to put a smaller speaker behind something, like a TV cabinet, the sound would be muffled.

However, the deeper bass sounds created by subwoofers aren’t directional like the other sounds. Therefore, you can have more choice about where you want to have it set up.
