KEF Announces Wireless Speaker System
KEF Wireless promises an easy installation of home audio -- with no strings attached.
January 08, 2007 by Rachel Cericola

The engineers at KEF set out to eliminate one of the most frustrating necessities in consumer electronics - - the speaker wire. The KEF Wireless system utilizes proprietary technology promising CD-quality audio without having to drill holes through the walls or leave cables lying around.

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.

  • $499.99
  • Available in Q1 2007
  • Wireless via proprietary 2.4GHz wireless transmission technology
  • HFADPCM (hi-fidelity adaptive differential pulse code modulation)
