The Sonos Sub (Gen 3) speaker for soul-shaking sounds and dramatic cinematic bass – this wireless subwoofer, with it’s sleek design, one-button set-up and upgraded internals is the best choice for your home entertainment.

Latest generation, powerful wireless SUB for your Sonos setup. New internals for faster processing and easier setup. Placing anywhere in the room, even under furniture, perfect for filling a room with rich, deep-sounding, bass.

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.
