The Sonos music system gets a bass-heavy addition with the Sonos SUB-- a wireless subwoofer promising to turn music into a "spine-curling, jaw-dropping, full body experience."

Now that's what we call dangerous-sounding PR talk!

Like all Sonos speakers, the Sub connects easily to existing Sonos networks with the press of a button. Thanks to a clever donut-style design, one can place the Sub anywhere within a room in either horizontal or vertical positions.

It carries x2 force-cancelling speakers (Sonos promises "all sound, zero vibration") while DSP circuitry handles filter settings, active equalisation and time alignment.

Powering all are x2 Class-D digital amps.

The cabinet is in proprietary resin, with acoustically dead walls creating maximum internal air volume.

The Sonos Sub works with all Sonos amplified compents and connects with the the Play:5, Play:3, ZonePlayer 100, ZonePlayer 120 and the Connect:Amp-- but not with the non-amplified Sonos Connect or ZonePlayers 80 and 90.
