The Sonos Sub Mini is a wireless subwoofer designed to provide low-frequency audio reinforcement for compatible Sonos soundbars and speakers. According to Sonos Australia, the cylindrical cabinet measures 305 mm in height and 230 mm in diameter, with a total weight of 6.35 kg. The sealed acoustic enclosure houses dual 6-inch inward-facing woofers powered by dual Class-D digital amplifiers. Sonos states this force-cancelling driver configuration reduces cabinet vibration and buzz while delivering frequency response down to 25 Hz.
Who it suits
This subwoofer suits owners of compact Sonos home theatre and audio equipment, including the Sonos Beam, Ray, One, One SL, and Ikea SYMFONISK bookshelf speakers. It is designed to add low-end depth to films, television, and music in small to medium-sized rooms without taking up the floor space required by a larger sub. The compact design allows placement beside lounge seating or beneath desks.
Prospective buyers should skip the Sub Mini if they need a standalone audio speaker, as it exclusively handles bass frequencies and cannot play audio independently. Sonos support documentation states that the Sub Mini cannot pair with portable battery-operated products, including the Sonos Move and Sonos Roam, nor with unamplified components such as the Sonos Port. Furthermore, households wanting dual subwoofers in a single setup cannot pair two Sub Minis together, as Sonos restricts dual-sub configurations to its standard full-sized Sub. Android users should also consider that Sonos Trueplay acoustic room tuning is strictly limited to supported Apple iOS devices.
Australian notes
The Sub Mini includes an internal 100–240 V, 50/60 Hz power supply and comes supplied with a detachable two-metre AC power cord compatible with Australian wall sockets. For wireless connectivity, the Australian product specifications confirm dual-band Wi-Fi support across 2.4 GHz and 5 GHz networks (802.11a/b/g/n), along with a 10/100 Mbps Ethernet port for physical network connections.
Regarding smart home platforms, the Sub Mini does not feature standalone compatibility with Apple Home, Google Home, Amazon Alexa, Matter, or Home Assistant, nor does it include built-in microphones. All grouping, playback, and volume adjustments are managed via the host Sonos speaker or through the Sonos app ecosystem.
Sonos provides a one-year limited manufacturer warranty in Australia. Buyers also hold statutory consumer rights under the Australian Consumer Law, and Australian retailers such as JB Hi-Fi provide a two-year voluntary warranty policy.
