Product details

The KEF KW2 RX Receiver picks up audio wirelessly from the XIO soundbar. It gives an active subwoofer more placement flexibility and can also connect selected KEF speakers as dedicated rear surrounds.

Connect a subwoofer

The four-pin connector plugs directly into compatible KEF subwoofers including the KC62, KC92, KF92 and Kube series. For a third-party active subwoofer, power the KW2 over USB-C and connect the receiver to the subwoofer’s compatible input using its combined 3.5 mm analogue and TOSLINK optical output.

Add rear surrounds

Optional wireless rear surrounds with LSX II, LSX II LT or Coda W via a separately sold KW2 RX Receiver. Requires XIO firmware 1.5.160 or later, transmitter and KW2 firmware 2.0.0.0 or later, updated speaker firmware and KEF Connect 1.32.0 or later.

The receiver uses a 2.4 GHz link from the XIO, with a rated line-of-sight range of up to 15 metres. The box includes USB-C power, optical and 3.5 mm-to-RCA cables, screw sets and a quick-start guide.
