Sonos SUB

I have used it a handful of times—no more than 5, if not less. I moved and never used it again. It is in mint condition. Here is a little bit more about the product.

Lower Lows and Higher Highs
Sonos Sub takes over the lowest frequencies, enhancing the midrange playback from paired speakers so you experience fuller, more detailed sound.

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

Made To Be Seen and Heard
Its versatile design features a slim, sculptural shape and high-gloss finish. You can stand Sub upright or lay it on its side.

Wi-Fi and Ethernet Connectivity
Stream via your Wi-Fi network, and wirelessly connect more Sonos speakers to expand your sound system.

Masterfully Engineered
The sub's sound ports strategically force the internal energy out of the cabinet to prevent muffling, while the specially developed resin resists vibration.
