Sonos Sub (Gen3) - White SUBG3AU1 review
The Sonos Sub, an expensive wireless subwoofer that's easy to adjust via app, isn't how you start a Sonos system, but it's a terrific addition to complete one.
Powerful, thunderous bass at highest levels; Subtle low-frequency anchoring at more modest volumes; User-controllable bass levels; Attractive design; Can sit vertically or be laid flat; Easy integration into existing Sonos systems.
Expensive; Large; Only works with Sonos speakers, cannot be physically connected to a subwoofer output.
