Sonos Sub Black Active subwoofer

No buzz, just bass
Two force-canceling drivers at the center of Sub eliminate vibration and rattle so you get powerful bass without any distortion.

Made to be seen and heard
The award-winning and versatile design features a sculptural shape and high-gloss finish. Stand Sub upright or lay it on its side.

Lower lows and higher highs
Sub takes over the lowest frequencies, enhancing the midrange playback from paired speakers so you experience fuller, more detailed sound.
