What is the purpose of a subwoofer in a home surround system?

Posted on May 26th, 2010 by admin

Will a home surround system be "OK" without a subwoofer?

Or is it an important component?

Subwoofers are designed to carry the lowest frequencies – like all the rumbling you hear in the movie theater. The biggest reason to have a subwoofer is due to most home theater surround sound systems not having large speakers for the rest of the channels. In fact a lot of them have very small speakers for everything else. So in essence you have midrange and tweeters for all the other 5 channels and the subwoofer used to carry the bass sounds. If your two main speakers (left and right front channels) are large – 10 inch woofers or larger then I would say a subwoofer is not an absolute necessity. However if your two main speakers are of the 4 – 5 inch variety then a subwoofer would make things sound much better.

After saying all that I must add that if you are OK with the sound without a subwoofer then that is all that really matters, so the decision is all up to you and your ears.
