Initially offered in two iterations; as an aftermarket solution for use with any existing speaker system, or as the 5000W system designed to complement the heralded KHT 5000 Series of products, the KEF Wireless System features a transmitter and two matching receivers. The receivers house two robust yet diminutive 50 watt digital power amplifiers.

KEF has developed a 2.4GHz wireless transmission technology that uses advanced error-protection and adaptive frequency-hopping to deliver an interference-free signal. This proprietary technology is pre-emptive and will change channels automatically to a pre-negotiated frequency (within the best available band) before any errors start to occur.

The company also says that the audio won't be affected by microwave ovens, cordless phones, or LAN routers, which means you can place them wherever you want.
