A specialized speaker, referred to as a subwoofer, is responsible for that deep bass experience. 1  The subwoofer is designed only to reproduce the lowest of audible frequencies. In home theater, this is often referred to as LFE (Low Frequency Effects.
Why would I need a subwoofer? If you have large floorstanding speakers then you will have speakers that can produce some power. The thing is though, the vast majority of speakers are capable of playing loud bass, but they simply don't reproduce the lowest frequencies that are in a soundtrack or a music track.
