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.
To me an essential item in any build, even a budget install, is a subwoofer. These speakers give extra âoomphâ to the bass notes of any piece of music and will give voices a warmer tone, helping to eliminate the harsh tinny sounds that is often apparent in the car.
