Demonstration cd for the KEF Reference Loudspeaker.Demonstrating the Uni-Q Drive Unit with its high frequency driver ticked neatly away in the centre of the mid-range unit. To do this KEF went to the top and utilised technology from the NASA space programme. The tweeter magnet is made from a rare earth material called Neodymium which is ten times more powerful than the usual ferrite. It's allowed us to make the tweeter small enough to sit in the centre of the mid-range unit (By the way, don't go looking for this sort of technology in any other loudspeaker, it's protected by a string of patents).
Uni-Q is protected under GB patent 2 236929.
