The Sonos Sub 4 is engineered to deliver deep, powerful bass while maintaining the effortless usability and clean design that defines the Sonos ecosystem. Built around a dual force-cancelling woofer configuration, the Sub 4 eliminates cabinet vibration, allowing bass energy to be focused entirely into the room rather than lost through resonance or distortion. This design ensures low frequencies remain tight, impactful, and well controlled, enhancing music playback, movie soundtracks, and gaming audio without overpowering the rest of the system. Wireless connectivity enables flexible placement anywhere in the room, while automatic tuning ensures seamless integration with compatible Sonos speakers and soundbars. The Sub 4 intelligently balances bass output to suit the room and system configuration, delivering consistent performance regardless of listening position. Its minimalist, sculptural enclosure allows it to blend discreetly into modern living spaces while delivering cinema-grade low-frequency extension. Designed for users who want powerful bass without complexity, the Sonos Sub 4 provides a refined, immersive low-end foundation that elevates the entire listening experience.
