A subwoofer for a compact system
The SB-900 adds a dedicated bass channel to a home theater or music system. It is also a companion for Atlantic Technology soundbars when you want a separate subwoofer alongside the front speakers.
Its Clear Filter Technology addresses the effect of the enclosure on bass reproduction. The amplifier and bass controls let you integrate the subwoofer with the rest of the system rather than treating it as a separate source of sound.
