Sonos' full-size wireless subwoofer — significantly larger than the Sub Mini, delivering deeper, more powerful bass for home theater and music setups. Two force-canceling drivers positioned face-to-face eliminate cabinet buzz and rattle even at high volumes, and the sculptural, high-gloss design can be placed vertically or laid on its side to fit any room.

• Dimensions: 15.3 x 15.8 x 6.2in (389 x 402 x 158mm), 36.3lb (16kg)
