KW2 receives wireless signals from the XIO Soundbar and transmits them to any subwoofer it's connected to. It effortlessly plugs into the back of any active KEF subwoofer, including KC62, KC92 and Kube. Third party subwoofers can be connected via Aux/Optical Combo output.

*KW2 is not compatible with speakers from the LS Collection. We recommend the KW1 Adapter Kit for connecting those speakers to  KEF subwoofers.
