Hi-Fi Subwoofers

A subwoofer is a speaker designed to play low audio frequencies, known as bass or sub-bass. The typical frequency range for a subwoofer is around 20-200 Hz for consumer products, below 100 Hz for professional live sound and below 80 Hz for certified THS systems. Subwoofers are never used alone, but paired with, for example, bookshelf, column or wireless speakers.
