”The Sonos multi-room system is still a great choice”. ’What Hi-Fi?’ 2020 Product of the Year.

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 Great addition to my Playbase & Surround Ones I've been happy with the sound from my Playbase and surround Ones since I set them up a couple of years ago, but it always felt like there was some depth missing. At £699 rrp the Sonos Sub is not an impulse buy, but after researching opinions it seemed that the overwhelming view was that it would be a worthwhile addition to my set up. Installation and configuration is very simple and quick via the Sonos IOS app and after using the Trueplay feature followed by some manual tweaking to levels for my open plan room, I can only say that the improvement to the overall sound is superb. The Sonos Sub doesn't just give you the level of bass that the other speakers aren't capable of, it frees them from trying and allows the Playbase & Ones to concentrate more on the mid & high end making spoken word so much more defined and clear. If you are contemplating adding the Sub to your system, you won't be disappointed if you decide to go ahead.

Rated 5 out of 5 by from Wow! Awesome sound!! The Sonos Sub Gen 3 is like the the icing on the cake. It is awesome!! I had already purchased the Sonos Beam & 2 x One SL’s last year which I was more than happy with, but felt it lacked depth. Not any more though, the sound is superb after purchasing my subwoofer. It was so easy to set up with the Sonos app. Music fills the room with fantastic bass and no distortion & to watch a film, you feel as though you’re in a cinema. Wish I’d bought it sooner now. Thank you Sonos for a fantastic set up, that I’d recommend to anyone.

Rated 5 out of 5 by from Filled the room! The Sonos Arc and two One SLs was a great setup but always intended to have the full package. Glad I did - the Sub added another dimension for films and music.

Rated 5 out of 5 by from Sounds amazing Those low bass tones are perfect. Turns a stereo sound pair of ones or fives in to a beautifully balanced music room

Rated 5 out of 5 by from Great design, easy to set up I bought this to supplement my recent purchase of an LG TV and Sonos Arc, along with two One SL speakers. Once plugged in, the Sonos app automatically set up the components as a surround sound system which sounds great.

Rated 5 out of 5 by from Awesome sound!!! A great piece of kit to add to your SONOS sound system. The sub woofer adds significant depth to my surround sound system, whilst expensive, well worth it. I might just add that the service offered was excellent and included a follow up call as well from the customer services team....
