March 04, 2010

Highlights

The Concept Blade loudspeaker is a showcase design that is not for sale, but displayed as a technological benchmark to represent the current direction of development from KEF. It has allowed them to put together a design that typifies the technologies currently under development and offers a hint of where they believe speaker design of future models will be.

The Concept Blade has a new 10th generation Uni-Q midrange driver with a liquid crystal polymer cone and a tweeter that has been under development for about 3 years, called Tangerine Wave technology it offers excellent vocal clarity and good transient response.

It utilises four 10” bass drivers in a back to back pair configuration that helps with voice cancelling and endorses their single point source design known as Single Apparent Source Technology.

The unique driver layout is possible due to the unusual but effective cabinet design that is straight out of the Formula 1 mould. Built buy a company called Prodrive who are usually associated with Formula 1 design, the cabinets are made from a carbon fibre layer with a balsa wood core that is then covered in another layer of carbon fibre. This gives a strong cabinet design, avoids box colouration and gives a smooth aesthetically pleasing baffle board.
