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.
Although these subwoofers are not quite as thunderous as the subwoofers employed at the local movie theater, these unique loudspeakers can still shake the house down or annoy the downstairs neighbors in your apartment or condo complex. Buying a subwoofer is a necessity when it comes to the home theater experience.
