A wireless subwoofer that adds deep bass to an existing Sonos soundbar or speaker without a signal cable. The listing names only Sonos gear as compatible, so it does not suit a receiver or another brand of soundbar.

Overview
A living room or home theater built around a Sonos soundbar gains low end from this wireless subwoofer, which joins the system over Wi-Fi and is controlled in the app. Dual force-canceling woofers inside a matte enclosure work to cut distortion.
Adding bass without a signal cable is the reason to own it, since the sub joins an existing Sonos setup over Wi-Fi and needs only a power outlet. Its limit is the ecosystem: the listing names only Sonos speakers and soundbars as compatible, so plan on a Sonos product to pair it with.
Who it's for
Suited to living rooms and media rooms where a Sonos soundbar handles movies and music but low end feels thin. Owners of receivers or other soundbar brands have nothing to pair it with.
Pros and cons
- Wireless link, only a power cable needed
- Dual force-canceling woofers reduce distortion
- App control within the Sonos system
- Matte white finish
- Pairs only with Sonos soundbars and speakers
- Heavy to move around the room
- Not water resistant
- No wired audio input listed
Performance notes
Bass quality rests on the dual force-canceling woofers, a layout the maker says virtually eliminates distortion. Placement and the Wi-Fi link to the Sonos soundbar or speaker shape real results, since the sub depends on that system for its signal.
