Things to consider before buying a subwoofer:

Passive Subwoofers

Passive subwoofers are powered by an external amplifier just like any other speaker that lying around you. However, if you go with a subwoofer, then you have to place an external subwoofer amplifier between the subwoofer and the home theater. As a result, the receiver will get free from supplying the needed amplifier power for the subwoofer.

Also as extremely low frequencies need more power to produce better sound quality. Hence you will require an external amp. However, a passive subwoofer is not always required unless you have a quite big room.

Powered Subwoofers

Powered subwoofers are one of the most common types of subwoofers that we get to see. These are basically self-powered subwoofers which means they have their own built-in amplifier. Also, the amplifier and subwoofer speaker optimally matched. Another good part of the powered subwoofers is that they offer their own volume (gain) and other setting controls which you can adjust according to your needs.

Front-Firing and Down-Firing Subwoofers

The front firing subwoofers help the mounted speaker to spread the sound from the side or front of the subwoofer. And on the other hand, the down-firing subwoofers allows the mounted speakers to throw the sound at the floor.

Both of this speakers can offer you similar results. However, according to some people, the front firing subwoofers are good if you place them on the front of the room. And the down-firing subwoofer is good for room’s corner or side wall.

Ports and Passive Radiators

Some of the subwoofers also come with some of the additional ports. These help in increasing bass response in an efficient way. Also, there is another type of subwoofer which known as the Passive Radiator.

This type of subwoofers is mostly a speaker who has the voice coil removed or a flat diaphragm. The subwoofer does not vibrate at all instead it reacts to the air that is pushed by the active subwoofer driver.


You may also look for a subwoofer which comes with a crossover. A crossover is an electronic circuit which helps in routing all frequencies below a specific point to the subwoofer. And all frequencies above that point are reproduced the main, center, and surround speakers. Overall, a good subwoofer comes with a crossover frequency of 100hz.

Deep Bass is Non-Directional

Also, you need to understand the fact that deep bass frequencies are reproduced by subwoofers which are non-directional. And it can be very difficult for us to figure out from where the sound is coming.

Wired or Wireless

The last thing that you need to consider is wired or wireless. Nowadays there are quite a lot of subwoofers are available which comes with wireless connectivity. And to be honest wireless subwoofers are actually good.

First of all, they kill the need for a long connection cable between the subwoofer and home theater receiver. All you need to do is connect the home theater to the subwoofer, and you are good to go.
