Enhance Your Home Cinema & Music Listening

Enhance Your Home Cinema & Music Listening

The Sub (Gen 3) can be added to any Sonos speaker (except Sonos Move*) to transform your listening experience and create a more impressive sound experience.

When adding Sub to other Sonos speakers Sub takes over the lowest frequencies, enhancing the mid-range playback from paired speakers to enhance your listening experience.

Pair it with the Sonos Beam or Arc to create a 3.1 Sonos home cinema setup. Take it one step further and add 2x Sonos One or One SL as surround sound rears for the ultimate immersive experience for your favourite films or TV shows. 

Clean, Deep Bass Without The Vibration

Clean, Deep Bass Without The Vibration

Sub (Gen 3) adds soul-shaking, dynamic bass by converting low frequencies into deep, rich bass. 

Experience the rumble in your favourite songs and the crashes and bangs in your favourite films. 

Internally, the cabinet houses two force-cancelling speakers (powered by separate Class-D amplifiers) which are positioned face-to-face to eliminate vibration. This ensures zero rattle or buzz and instead projects all the energy into the room.

Sleek Design To Fit Any Room

Sleek Design To Fit Any Room

The Sub (Gen 3) boasts refreshed design features including a flat power cord to avoid cables getting tangled and a round join button for a more ergonomic design. The premium aesthetic and sleek design comes in a choice of gloss black or white finish to suit any room.

If you are looking for a more discreet look, the Sub can be laid flat or even placed beneath a sofa without impacting the performance. 

Wireless Connection & Simple Setup

Wireless Connection & Simple Setup

Adding the Sonos Sub to another Sonos speaker is quick and simple. With no complicated wiring, simply plug in and press the connect button on the back of the Sub and add to your system via the Sonos app.
