Hear and feel the difference when you add Sub to a room in your Sonos system. Experience every rumble, roar, and beat you've been missing with clean, pulse-pounding bass. Made to be seen and heard, Sub features a sculptural shape and high-gloss finish. Stand it upright or lay it on its side. Sub takes over the lowest frequencies so paired speakers are free to focus on mid-range and high frequencies for a richer, more powerful sound experience all around. A pair of precisely engineered force-cancelling drivers eliminate all vibration, buzz, and rattle.
