With more brainpower behind the brawn, the Sonos Sub is better than ever.

All the brawn
The key USP behind a subwoofer is to provide deep and sustained bass. The Sonos Sub doesn't disappoint on either front. Using twin, force-cancelling drivers with separate Class D amplifiers, the Sonos Sub provides a bass that is not only deep enough to rattle the windows, but also punchy, agile and dynamic. The bass simply sounds exactly as it should - fast and deep with zero cabinet buzz or rattle.

And now brainer than ever
The Gen3 version of the Sonos Sub features updated internals with increased memory, processing power and enhanced ability to accept future upgrades. When combined with the new Sonos S2 app, the Sub becomes the smartest subwoofer around. The app also gives you access to an adjustable EQ, for sound tailored to your preferences.

The Trueplay revolution - giving you tailored sound
The Sonos Sub also features revolutionary Trueplay technology. Trueplay scans your room, analyses the results and then fine-tunes the Sub for the ideal listening experience. Whether your room is large or small, densely furnished or minimalist, the Sub adapts to give the most natural and realistic sound possible (iOS device required).

Sonos style
There are subwoofers and then there’s the Sonos Sub. Available in gloss white or gloss black, the smoothly styled Sub looks way more stylish than the usual subwoofer. Sonos has even considered those really pushed for space as the Sub also functions horizontally as well as vertically, making it easy to place under a chair or sofa.

Made for your Sonos system
As you'd expect from Sonos, the Sonos Sub Gen 3 is a breeze to set up. With no wiring or programming required, simply press one button and follow the prompts from the Sonos app. It automatically adjusts the audio settings to ensure that the Sub is fully optimised to work with your paired Sonos components.

Feel the sound of the cinema and stadium, at home, with the powerful Sonos Sub.

Rated 5 out of 5 by from Sonos, Just Know How How to Build Quality!! Have to say first that Richer Sounds Customer Service, where pretty much why I bought this from them and SO glad I did !! A top quality piece of kit that just takes the Sonos Arc experience to another level. Can’t recommend enough, very happy customer.

Rated 5 out of 5 by from Excellent sub, worth every penny! I bought this recently to de-clutter from an old home theatre system which though good, took far too much space with wires everywhere and a pretty redundant DVD player. I had the Beam, but despite great mid range sound it lacked the "oomph". Mulled over the price tag for the Sub as it seemed a bit pricey, but then decided to go for it and I was blown away by the difference in the sound especially when watching films. Fantastic range, very easy to set up and add to existing Sonos units. Trueplay works a treat if you have ios. I can also play music from my playlist in the living room and it adds an extra dimension! I absolutely don't regret having purchased it one bit now!

Rated 5 out of 5 by from Amazing base & looks the part Got this as part of the cinema surround system & it’s money well spent. Ultra modern looks with an amazing sound range, sounds as good as the cinema itself :-)

Rated 5 out of 5 by from Great Upgrade Having recently changed to a wireless speaker system usina a sosos arc and 2 side speakers I read an artickle on the sub and decided to add it to my system. The change was brilliant when listening to my music collection the improvement was substantial.

Rated 5 out of 5 by from Looks amazing and sounds even better Matched the sub up with my Sonos beam and two Sonos ones and I couldn’t be happier. Unlike some sprouts systems it’s not in your face while watching normal tv but great when it needs to be. Music playback is superb
