Sub 4

Premium Wireless Subwoofer

Sub 4 unlocks the full power of Sonos sound to immerse you deeper in every scene and song.

Pair Sub 4 with your Sonos soundbar or speaker for a difference you can hear and feel. Dual force-cancelling woofers deliver pulse-pounding bass and virtually eliminate distortion. Updated with a matte finish, the iconic design looks great in your home. Set it up in minutes — just plug in the power cable and open the Sonos app. Sub 4 connects to your system through WiFi, so you can put it where it looks and fits best in the room. Stand it upright or lay it on its side and hide it under your sofa. Pair two with Arc Ultra or Arc for bass so deep and sound so cinematic, you’ll forget you’re not in an actual theatre.

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.

Lower lows

Zero distortion

A pair of precisely engineered force-cancelling drivers eliminate all vibration, buzz and rattle.

Wireless and stress-free

Quickly add Sub 4 to your system over WiFi with a little help from the Sonos app.
