Sonos Sub Mini Wireless Subwoofer, Black

Deep bass down to 25 Hz from a compact 23 cm cylinder.

The Sonos Sub Mini is a wireless subwoofer for Sonos systems: it pairs with a speaker or soundbar over Wi-Fi and takes over the low frequencies. The sealed cylindrical cabinet with a central tunnel stands upright next to the main speaker and needs only a power outlet.

Two opposing 6-inch woofers with no cabinet rattle

The two drivers sit face to face and cancel each other's motion, so the cabinet stays silent and does not creep across the furniture on heavy bass notes. Each driver is powered by its own Class-D digital amplifier.

Bass down to 25 Hz from a sealed cabinet

The sealed architecture keeps the low end tight and free of port noise, while the central tunnel moves air efficiently. Equalization and advanced limiting algorithms keep everything under control as levels rise.

Level and phase control from the Sonos app

The app adjusts sub level, phase (0° or 180°) and on/off, while automatic EQ balances the sound with the paired speaker. Trueplay tunes playback to the acoustics of the room.

Wi-Fi connection or wired Ethernet

Connectivity covers 2.4 GHz and 5 GHz Wi-Fi with 802.11a/b/g/n/ac/ax routers, and an Ethernet port on the rear panel is there for a wired install. The Join button adds the unit to the system during initial setup.
