DESC: The Acoustimass® 16 Series II speaker system increases the impact of home theater listening with a rear center speaker for even greater drama and realism. This heightened experience in music and motion picture listening is the result of a powered Acoustimass module. This innovative module uses proprietary Bose technology to bring depth to the rumble of a passing train, or the resonance of a baritone's voice. The module can be hidden nearly anywhere in the room.
