KW2 RX Receiver

KW2: Wireless connection from XIO to subwoofers and rear speakers
KW2 RX is a versatile wireless adapter designed to expand your audio setup without the need for long speaker wires spanning the room. This multi-functional device links XIO to KEF's wide range of subwoofers - including KC62, KC92, and KUBE - for optimal bass placement, while also serving as the wireless bridge to connect XIO with LSX II, LSX II LT or Coda W as dedicated rear speakers*. Setup is completed through the KEF Connect app, once the firmware on both XIO and the dedicated speakers has been updated to the latest version. 

*Additional wireless surround feature with LS60 Wireless, LS50 Wireless II, and LS LUXE will be available in a future firmware update.

Wireless Connection With Rear Speakers

KW2 transforms LSX II, LSX II LT, or Coda W into rear surround channels alongside the XIO soundbar, completing a multi-channel cinema setup without running lines of wire across your room.

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.

Wireless 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 concel the exposed pins.
