Pulse-pounding power

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

No buzz or rattle

The acoustic architecture creates a force-cancelling effect that virtually eliminates distortion.

Better sound all around

Sub 4 takes over the lowest frequencies so your paired soundbar or speakers can deliver high and mid frequencies with even greater clarity and precision.

Perfectly tuned for the room

Trueplay™ optimizes the sound for the unique acoustics of your space so the bass never sounds harsh, muddy, or flat — even if you place Sub 4 next to the wall or lay it flat and put it under your sofa.

Iconic design

Made to be seen, heard, and felt. Sub 4 features an elegant sculptural shape and updated matte finish that perfectly matches your paired Sonos soundbar or speaker.

Plug and play
