The Sonos Sub 4 is a premium wireless subwoofer engineered to deliver deep, powerful bass for movies, music, gaming and home entertainment. Dual 5 x 8-inch elliptical woofers face inward to create a force-cancelling effect that virtually eliminates unwanted vibration and distortion, while the ported acoustic design extends bass response down to 25 Hz. Wi-Fi 6 provides reliable wireless integration with compatible Sonos soundbars and speakers, and Trueplay room tuning optimises low-frequency performance for your space. With flexible upright or horizontal placement and a refined matte finish, Sub 4 brings greater depth, impact and clarity to premium Sonos home cinema systems.
