Sonos is best known for wireless audio devices like networked speakers or connecting gadgets that turn your stereo or home theater system into a wireless audio system that can play music from your computer or mobile device.
The company typically hasn't dabbled in audio components, preferring either adapters, systems, or self-contained speakers like the Sonos Play:3. But Sonos is changing that with the Sonos SUB, its first wireless subwoofer.
Since subwoofers are the most power- and space-intensive components of speaker systems, they were left out of Sonos speaker systems - until now. The SUB accesses the same wireless network as other Sonos products, like the Play:3 and ZonePlayer 100. Since subwoofers are specifically for bass response, it's intended to work with other speakers or satellites connected through a Sonos device, adding extensive bass to the system. By just plugging the SUB into a power outlet, it can connect to other Sonos-networked speakers, producing a full audio system without cables.
The SUB has two drivers that face each other in an open cabinet, reducing the vibration of the subwoofer itself by having each driver's movement cancel the other's out while two acoustic ports channel the sound outward. It uses two class-D amplifiers to power the drivers, and weighs in at a solid 36.3 pounds.
As a Sonos device, the SUB only works with Sonos wireless music network devices. While it's wireless, it doesn't work with Bluetooth, AirPlay, or other wireless speaker standards not developed by Sonos.
The Sonos SUB ships in mid-June and will be available for $699.
