Sonos Sub 4 Wireless Subwoofer

Sub 4 unlocks the full power of Sonos sound. Pair this subwoofer with your Sonos soundbar or speaker for pulse-pounding bass that immerses you even deeper in films, TV, and music. Updated with a matte finish, the iconic design features dual force-cancelling woofers that virtually eliminate distortion.

Pulse-pounding bass:
Dual Sonos-engineered drivers generate deep, dynamic low frequencies. The ported enclosure enhances the bass response so you feel every beat, roar, and rumble in your chest.

Transform your home cinema experience:
Pair Sub 4 with Sonos Arc Ultra, Arc or Beam for dramatically deeper bass and clearer highs that draw you deeper into films, shows, and games.

Bring your music to life:
Hear the nuance in every note and enjoy a greater sense of spaciousness when you pair Sub 4 with Sonos Five, Era 300, or Era 100.

No buzz or rattle:
The acoustic architecture creates a force-cancelling effect that virtually eliminates distortion.

Perfectly tuned for the room:
Trueplay optimises the sound for the unique acoustics of the room and placement of your speakers.

Iconic design:
With its elegant sculptural shape and updated matte finish, Sub 4 is designed to look great in your home and to match your Sonos speakers.

Plug and play:
Simply plug in the power cable and open the Sonos app to add Sub 4 to your system.

Place it where and how you want:
Sub 4 reliably connects to your Sonos soundbar or speaker over WiFi so you can place it anywhere in the room – even on its side and under your sofa.

Double the drama:
Pair two with Arc Ultra or Arc for bass so deep and sound so immersive, you’ll forget you’re at home and not in an actual cinema.

Toned-down impact:
Sub 4 uses fewer materials and is more energy efficient than previous generations.

Upgraded technology:
With increased processing power, memory and new WiFi radios, Sub 4 is the most advanced Sonos subwoofer to date.
