A dedicated bass channel
224SB is a powered subwoofer for a music or home theater system. Its job is to handle bass alongside the main speakers, with its own cabinet and amplification.
Position and setup affect how a subwoofer behaves in a room. Work through the level, crossover, and receiver settings before judging the balance from the listening position.
