About the KW2 RX
The KEF KW2 RX is a wireless receiver designed to let the KEF XIO soundbar send subwoofer audio wirelessly to a compatible KEF active subwoofer or, via its combo output, to many third-party powered subwoofers. It connects directly to KEF subwoofers that have the proprietary expansion port, and it can also feed analog or optical inputs on other subwoofers. The unit is compact, USB-C powered, and supports low-latency 24-bit/48 kHz audio over a 2.4 GHz wireless link.
