Sonos Sub 4 – Wireless Subwoofer – Black
In practical use, the Sub 4 should noticeably deepen bass response and improve immersion across films, games, and music. Its wireless integration and force-canceling design help it remain cleaner and easier to position than many traditional subwoofers. Pairing two Sub 4 units with an Arc Ultra or Arc can create an even more powerful low-frequency experience, particularly in larger entertainment spaces. Read below for more information or see the foot of this page for some alternative offers on subwoofers, soundbars, and speakers.
What we like about the Sonos Sub 4
Deep, room-filling bass performance
The Sonos Sub 4 is designed to dramatically improve low-frequency performance when paired with compatible Sonos soundbars or speakers. Its dual Sonos-engineered woofers generate deeper bass extension and greater dynamic impact than standalone soundbars can typically achieve on their own.
This makes explosions, soundtrack basslines, cinematic effects, and drum-heavy music feel more physical and immersive. The additional low-end presence also helps larger rooms feel fuller during movies and TV viewing.
Force-canceling acoustic architecture
One of the most technically important aspects of the Sub 4 is its force-canceling driver layout. By positioning the drivers to oppose each other, Sonos reduces cabinet vibration, distortion, and unwanted resonance. This allows the subwoofer to deliver stronger bass without excessive rattling or muddiness. That cleaner bass response helps improve overall system balance, because the paired soundbar can focus more heavily on dialogue clarity and mid/high-frequency detail rather than trying to reproduce deep bass itself.
Flexible wireless integration
Like other Sonos products, the Sub 4 connects wirelessly over Wi-Fi, which simplifies placement significantly compared to traditional wired subwoofers. Users can position it upright beside furniture, horizontally beneath sofas, or elsewhere in the room without needing long subwoofer cables running across the floor. The Sonos app also simplifies setup, tuning, and integration with other Sonos products, making it easier to build a broader multi-room or surround-sound ecosystem over time.
Who should buy the Sonos Sub 4?
The Sonos Sub 4 is ideal for Sonos users who want to expand a Beam, Arc, Arc Ultra, or other Sonos setup into a more cinematic home-theater system. It is particularly beneficial for users watching action movies, gaming, listening to bass-heavy music, or filling larger rooms where standalone soundbars may sound comparatively thin.
