Subwoofers FAQs 

What are subwoofers, and what do they do?

Subwoofers produce the lowest frequency sound that other speakers in an audio system are incapable of reproducing without distortion. The best subwoofers free your loudspeakers from the demanding chore of reproducing the bass, thus improving the sound of your overall system.

Do I need a subwoofer in my speaker system?

Subwoofers play a crucial role in a complete speaker system. A good sub will enhance the sound of your audio system and deliver undistorted playback down to the deepest levels. We recommend you start with at least one subwoofer so you can feel and experience the full sound of your system.

Do I need one or two powered subwoofers?

Using two subs will improve bass distribution by filling in gaps where the bass response may be weak throughout the room. Having a second sub will also supply more compelling dynamics and a wider soundstage.

Where do I place my subwoofers?

Since bass frequencies are omnidirectional, subwoofers have limitless placement flexibility around a listening room. If you place your subwoofer near a wall, it will result in more bass. If you place it near a corner, it will produce even more bass. Most people put their sub toward the front of the room, so it is easier to connect to their home theater receiver.

What is the difference between a woofer and a subwoofer?

In simple terms, a woofer is typically used in a full range floor standing or bookshelf speaker. A subwoofer is a woofer that is designed specifically to produce low-pitch audio frequencies, otherwise known as bass.

What is the difference between an active and a passive subwoofer?

A powered or active subwoofer holds a speaker and amplifier that are matched for best performance quality and housed within the same enclosure. A passive subwoofer needs to be powered by an external amplifier.

What is a subwoofer amplifier? Do I need one?

An amplifier intensifies the musical signal to make the sound louder or softer when controlling the volume of a sub. A passive subwoofer cannot work without an amplifier. Powered or active subwoofers do not need an amp because the amps are inside the sub.

How do I choose the right size subwoofer for my speaker system?

When choosing the size of your sub it is important to pick one that blends in with your speakers to create that immersive listening experience. If you have a big, open listening area, a large subwoofer is a good fit considering it moves more air which in turn produces more bass. If your sub is going into a small, cozy room, a smaller size would be suitable, so it does not overpower your listening space.
