KW2 RX Receiver
Wireless Connection from XIO Soundbar to any Subwoofer
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 Wireless Collection. We recommend the KW1 Adapter Kit for connecting those speakers to KEF subwoofers.
Flexible subwoofer placement
KW2 allows you to wirelessly connect the XIO Soundbar with a KEF subwoofer. It allows subwoofers to be optimally placed in the room without being limited by cables.
Easy connection with KEF subwoofers
Four connector pins ensure uninterrupted transmission from the XIO Soundbar to the subwoofer without the need for any cables. KW2 works seamlessly with KC62, KC92, KF92, and Kube subwoofers, enhancing your sound system with flawless connectivity.
AUX/Optical combo output
KW2 also caters for pairing XIO with third party subwoofers. Simply plug the receiver into a power supply using a USB-C cable and connect it to any subwoofer via the Aux/Optical Combo output on the side. Use the included cover to conceal the exposed pins. A USB-C power adapter is required in this configuration, sold separately.
