KEF KW2 RX Receiver

KEF KW2 RX Receiver

The KEF KW2 RX Receiver is a compact wireless accessory designed to connect the KEF XIO Soundbar to a compatible subwoofer without the need for a long wired connection. It is a smart solution for customers who want more freedom with subwoofer placement while keeping the overall system cleaner and easier to integrate into the room.

KEF designed the KW2 to work seamlessly with active KEF subwoofers including the KC62, KC92, KF92, and Kube range. It can also be used with third-party subwoofers through its Aux/Optical Combo output, making it a flexible option for a wider range of system setups.

Why Choose the KEF KW2 RX Receiver?

The KW2 is a great fit for customers who want the benefits of a subwoofer with the XIO Soundbar, but do not want to be restricted by the location of a sub cable. By sending the subwoofer signal wirelessly, it gives far more flexibility when choosing the best position in the room for bass performance and room layout.

It is also useful because it is not limited only to KEF’s own subwoofers. If you are using a third-party active subwoofer, the KW2 still gives you a neat way to integrate it with the XIO through the available analogue or optical connection options.
