The Sonos Sub 4 brings deeper, more powerful bass to compatible Sonos home cinema and music systems. Its dual Sonos-engineered 5 × 8-inch elliptical woofers face inwards to create a force-cancelling effect that virtually eliminates distortion, while the ported enclosure enhances low-frequency output.

With bass response extending down to 25Hz, Sub 4 adds impact and depth to films, TV, music and games. It connects wirelessly to compatible Sonos products over Wi-Fi, giving you flexibility over placement without the need for a traditional subwoofer cable.

Trueplay automatically analyses the acoustics of your room and adjusts the system for a more balanced performance, while the Sonos app provides control over bass, treble and loudness.

Sub 4 can be positioned upright or horizontally, including underneath a sofa where appropriate, making it easier to integrate into different room layouts. Its updated matte finish is available in black or white to complement the latest Sonos speakers and soundbars.

For home cinema, Sub 4 can be paired with Sonos Arc Ultra, Arc and Beam, while it is also compatible with products including Sonos Five, Era 300 and Era 100. Two Sub 4 units can be used with compatible Sonos home cinema systems for increased low-frequency performance.
