Sonos Premium Wireless Subwoofer - Sub 4 (B)

Bring music to life

Discern every subtle detail and enjoy a more spacious soundstage 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.

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

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

Place it where you want

Sub 4 connects to your system over WiFi, so you can place it where it fits and looks best in the room.
