KEF KW2 RX Receiver
Enjoy more flexible subwoofer placement with the KEF KW2 RX Receiver, a compact wireless adapter designed to connect the KEF XIO Soundbar to a compatible subwoofer without the need for long audio cables.
The KW2 receives wireless audio from the XIO Soundbar and sends the signal directly to the subwoofer it is connected to, helping you position your subwoofer where it performs best in the room. This makes it easier to achieve deeper, more balanced bass while keeping your entertainment space neat and cable-free.
For KEF subwoofers, the KW2 plugs directly into the rear connection point for a clean and reliable wireless setup. It is compatible with models including KC62, KC92, KF92 and Kube subwoofers. Third-party active subwoofers can also be connected using the Aux/Optical Combo output, giving you added flexibility when building or upgrading your home cinema system.
With 2.4 GHz wireless transmission, 24-bit/48 kHz resolution and a maximum line-of-sight range of up to 15 metres from XIO, the KEF KW2 RX Receiver is a simple and effective way to add powerful low-frequency performance to your soundbar setup.
Please note: the KW2 RX Receiver is designed for use with the KEF XIO Soundbar and is not compatible with KEF LS Wireless Collection speakers.
