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 (not included), and plugs into a USB wall adapter (not included) for power.

This kit is also a handy way to add a compatible sub to KEF powered speakers like the LSX or LS50 Wireless models.
