Connect your KEF subwoofer wirelessly
Connect your KEF subwoofer wirelessly
This adapter kit lets you make a high-fidelity wireless connection to your KEF Kube or KF92 powered subwoofer. That makes placing the sub a little bit easier, because you won't need to tether it to your home audio system by a physical cable. The kit's wireless range is up to an impressive 100 feet, line of sight.
This package includes a compact transmitter that connects to your receiver, amplifier, or preamp via a stereo RCA cable. The transmitter is powered by a USB wall adapter (not included). The kit's receiver unit mounts on the back of your compatible KEF subwoofer and plugs directly into the sub's expansion port for power and signal. This kit is also a handy way to add a compatible sub to KEF powered speakers like the LSX or LS50 Wireless models.

Cool product... and it was free with my speaker order. Functional. Does not come with a "power block" for the usb connector.... weird and unknown until hook up. Also, directions make it tough to figure out exactly what you are missing?!
