The wireless subwoofer for deep bass. Hear and feel the difference when you connect Sub to your Sonos system. Two force-cancelling drivers at the centre of Sub eliminate vibration and rattle so you get powerful bass without any distortion. The award-winning and versatile design features a sculptural shape and high-gloss finish. Stand Sub upright or lay it on its side. Sub takes over the lowest frequencies, enhancing the midrange playback from paired speakers so you experience fuller, more detailed sound.
