SONOS Sub Gen 4

Smartech SONOS Sub Gen 4

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.¹
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 100.¹
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.¹
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.
