You’re not just filling the room. You’re grounding it.
 
The SA250 Mk2 is the heartbeat of Bowers & Wilkins in-wall subwoofers. Designed to integrate seamlessly with the ISW series, this amplifier offers tight, clean bass that doesn't overpower — it supports. With 250 watts of Class D power, it's more than enough to energize the low end of any home theater or music system without distortion or boominess.
 
Brand new, in box, and backed by AV Synergy. The foundation your system has been waiting for.
