Overview
Wireless bass for a Sonos system is what the SUBM1US1 subwoofer delivers, pairing a 6 inch driver and 250W of power over Wi-Fi rather than a wired line-in.
Unlike a wired subwoofer that plugs into a receiver, this unit joins a Sonos system over Wi-Fi, which means setup runs through the Sonos app rather than a cable connection. It's a floor-standing design finished in white rather than the usual black seen on most subwoofers. A listed weight figure in the source data looks inconsistent for a unit this size, so it has been left out here pending confirmation.
- 6-inch driver
- 250W power
- Wi-Fi connectivity

Who it's for
Fits existing or new Sonos households wanting to add bass output to their wireless speaker system. Not for anyone needing a subwoofer wired directly into a traditional AV receiver.
Pros and cons
- 250W power rating
- Wireless Wi-Fi connection to a Sonos system
- White finish available
- Requires an existing or new Sonos system to use
- No wired input listed
Performance notes
The 250W power rating and 6 inch driver work through Wi-Fi rather than a physical line-in, so the subwoofer pairs with other Sonos components over the same network connection. Floor-standing placement is the intended setup based on the listed mounting type.
