Sonos Sub Gen4

Deep bass you can both hear and feel

The Sonos Sub 4 unleashes the full power of your Sonos system, delivering deep, physical, and controlled bass that takes movies, TV, and music to a whole new level. With dual powerful woofers, advanced signal processing, and an iconic design, the Sub 4 is made for those who want maximum immersion – without distortion, rattling, or compromise.

The Sub 4 connects wirelessly via Wi-Fi and can be placed freely in the room, standing or lying down – even under the sofa.

Pulsating bass without distortion

The Sub 4 uses two Sonos-developed woofers that operate in a force-cancelling configuration. The drivers are aimed inward, cancelling out each other's vibrations, effectively eliminating distortion, hum, and resonances – even at high volumes.

The ported cabinet enhances bass reproduction, providing a punchy, deep, and controlled low end that extends down to 25 Hz.

Transform your home theater

When the Sonos Sub 4 is paired with a compatible Sonos soundbar, you get:

• Deeper and more physical bass

• Clearer dialogue and midrange

• A more immersive and cinematic soundstage

For maximum effect, two Sub 4s can be used together with selected soundbars for an even larger and more dramatic sound.

Music with more weight and space

The Sub 4 isn't just for movies. Paired with Sonos speakers, music gains:

• More depth in the bass

• Better separation in the midrange and treble

• A larger and airier soundstage

Perfect for both focused listening and background music.

Optimized for your room with Trueplay

With Trueplay™, the Sonos app analyzes the room's acoustics, and the subwoofer automatically adjusts to its placement and surroundings. The bass integrates seamlessly with your other Sonos speakers and dynamically adapts to volume and content.

Easy installation and flexible placement

• Plug in the power cable

• Open the Sonos app

• Add Sub 4 in minutes

The Sub 4 connects wirelessly via Wi-Fi, but also has an Ethernet port for wired connection if desired. Thanks to wireless communication, the subwoofer can be placed exactly where it fits best – both acoustically and visually.

Iconic design – built to be seen (or hidden)

The updated matte finish and sculptural form make the Sub 4 a stylish addition to your home. At the same time, the design is discreet enough to be easily hidden behind or under furniture.
