The wireless subwoofer for deep bass from Sonos. Hear and feel the difference when you connect Sub to any Sonos system. Two speaker drivers at the centre of Sub face inward to eliminate vibration and rattle so all you hear is pure bass. Enhance your listening experience when you wirelessly connect Sub to any Sonos system. Add more dimension to home theatre when you pair Sub with Beam, Playbar, or Playbase, plus a pair of Sonos Ones for surround sound. Stand Sub upright or lay it on its side. You can even tuck it under the couch.
