The Sonos Sub 4 is the most advanced Sonos subwoofer yet — delivering deep, powerful bass down to 25Hz that you don't just hear, you feel. Dual 5" x 8" elliptical woofers face inward in a force-cancelling configuration, virtually eliminating distortion, buzz and rattle even at the highest volumes.
Pair it wirelessly with the Sonos Arc Ultra, Arc, Beam, Era 300 or Era 100 and transform your home cinema and music experience overnight. The ported cabinet enhances bass response, while Trueplay automatically tunes the Sub 4 to the acoustics of your room. WiFi 6 and a 10/100 Ethernet port mean you can connect it however suits you best, and flexible placement lets you stand it upright or lay it flat — even hidden under a sofa.
Under the hood, the Sub 4 features a faster processor, more memory and updated WiFi radios compared to its predecessor, making it the sharpest, most responsive Sonos sub to date. For the ultimate home cinema experience, pair two Sub 4s with the Arc Ultra.
