The Low Down on Subwoofers
Filed Under Home Theater Speakers
Sorry for the cheesy post title, it really was the first thing that popped into my head. Recently I was asked “Well, what does the subwoofer do?” It was a perfectly innocuous question but I was caught off guard, every now and then a good jolt of (not everyone lives and breathes this stuff) reality is just what the doctor ordered. So with that and in a very small nutshell this is what a subwoofer does.
A subwoofer is meant to compliment your existing front channel speakers in either a 2-channel (stereo) or home theater (multi-channel configuration) setting. The subwoofers purpose is to reproduce bass information at frequencies lower than your front channels speakers are capable of reproducing.
In other words, your front speakers may perform like champs from 18kHz to 45Hz but may run out of steam completely below 40hz (low bass). This is where the subwoofer comes in and takes over for the front channels. The benefit is twofold, the front channels are able to focus on what they do best namely treble, midrange and the upper to mid bass range, and the subwoofer is left to do what it does best, low bass.
