Breathe new life into your movies, TV shows, and music when you add the Sonos Sub 4 Wireless Subwoofer to your existing compatible Sonos soundbar or speaker. This 4th generation black-colored Sonos Sub features a matte finish and works with many existing Sonos speakers, such as the Arc and Arc Ultra, Beam, Sonos Five, Era 100, and Era 300. Setup is a breeze, requiring only a power cable connection and the Sonos mobile app. The subwoofer pairs to other speakers wireless via dual-band Wi-Fi 4 (802.11n). Delivering this increased immersion and pulse-pounding bass are two 5 x 8" elliptical woofers. They face inward in a force-cancelling configuration to virtually eliminate distortion, leaving you with rumbling bass frequencies as low as 25 Hz.

Sonos Sub 4 Reviews
Love the quality

It is a really really good. Thought that the soundbar arc will be enough but the subwoofer enriched the overall experience 5 folds. Subtle low vibrance bass was picked up. Simply great!
Really Helps The Sound of the ARC Ultra Sound Bar

Great BASS reproduction - even located on a side wall as is the case in my living room. One thing (pleasantly) surprised me: the Sub handles the Bass sounds and the soundbar doesn't have to - yielding a much better overall sound. Aa great companion for the ARC soundbars.
