Active subwoofer Sonos Sub Mini White — 6" driver, Class D amp, 23×23×30.5 cm

Sonos Sub Mini White is an active subwoofer with a 6" driver and a Class D amplifier, engineered to extend low-frequency performance for Sonos speaker systems. The compact cabinet (23×23×30.5 cm) and AC power compatibility (100–240 V, 50–60 Hz) make it suitable for placement beside furniture, under a desk, or near a TV. Sub Mini connects over WiFi and integrates with Sonos speakers and soundbars to deliver deeper, clearer bass without occupying much space. The unit includes an AC cable and supports app-guided setup and tuning.

Advantages

Dual inward-firing woofers create a force-cancelling design that reduces distortion and eliminates buzz or rattle while producing full-toned low frequencies typical of larger subwoofers. Built-in digital processing and Trueplay™ tuning adapt bass output to room acoustics so low end remains balanced and detailed. Wireless connection via 5 GHz WiFi ensures reliable, low-latency audio when paired with compatible Sonos products. The cylindrical, compact form factor blends with home decor and provides flexible placement options.

• Enhancing home cinema sound with Sonos soundbars (Beam, Ray) for more impactful movie and TV audio
• Adding depth to music playback when paired with Sonos One or One SL speakers

How to use

Place the Sub Mini where it fits best in the room — beside furniture, under a desk, or near your TV — keeping the AC outlet accessible. Plug in the included power cable, open the Sonos app on a supported device, and follow the app-guided setup steps to add Sub Mini to your Sonos system. Pair it with a Sonos soundbar or speaker to route low-frequency content to the subwoofer. Use the Sonos app to adjust the crossover and bass level as needed; volume will synchronize automatically with paired Sonos components.

Usage recommendations

For optimal bass performance, run the Trueplay™ tuning procedure (requires a supported iOS device) after placement to adapt the Sub Mini to your room acoustics. Allow a short break-in period for the driver to settle for the most accurate low-frequency response. Place the sub away from direct obstructions to preserve airflow and avoid covering the cabinet. For home theater setups, pair Sub Mini with Beam or Ray over 5 GHz WiFi to minimize audio latency and maintain tight synchronization with your TV.
