Overview
Not a standalone speaker, the Sonos Sub is a wireless bass unit that joins a Sonos system over Wi-Fi, stands on the floor in a polycarbonate enclosure and is set up from an app.
Sonos ships the sub with a power cable and gives it app control on Android and iOS, with a wired network port as a backup. The battery, radio and range entries do not suit a corded home sub, so ignore them.
Who it's for
Owners of a Sonos soundbar or home theater who want wireless bass without running cable suit this sub. Shoppers outside the Sonos system should choose a standard subwoofer.
Pros and cons
- Power cable included
- Needs a Sonos system
- No RCA input listed
- Some entries do not fit a corded sub
Performance notes
A bass driver reinforces the low end of a Sonos system, and the wireless link carries the bass signal over the home network. Placement near a wall or corner changes level, and a stable network connection matters for dropouts. The app handles setup and tuning.
