About Kef....

• Innovation is what sets kef apart. It's why we were founded, and why we've always attracted some of the world's most gifted acoustic engineers.
• The results are plain to see, in long lists of breakthroughs that no other manufacturer can match - and we have the patents and academic papers to prove it.
• Right from the start, we pioneered the use of synthetic materials for diaphragms and driver surrounds to maintain consistent sound quality across the frequency range.
• In the mid-sixties, we were the first to commercially exploit the stability of bextrene as a cone material, with a range of drivers that found their way into many leading audiophile speakers.
• A hugely important breakthrough came a few years later, when kef became the first company to use computers in loudspeaker testing and design.
• Having led the industry in the digital analysis of speaker behaviour ever since, this unrivalled capability is what still underpins kef's technological supremacy. 
• The next decade saw the appearance of kef's signature technology, the uni-q point source driver array. Using nasa-developed magnets ten times more powerful than conventional materials allowed us to engineer a tweeter small enough to mount at the acoustic centre of the bass unit voice coil so that both acted as one. 
• With the advent of 5:1 home theatre recordings in the nineties, kef was once again ahead of the game by applying the performance advantages of uni-q to the uk's first dedicated centre speaker, the model 100. 
• Other kef firsts include the first motorised ceiling speaker and acoustic compliance enhancement technology, which achieves truly full-bodied bass performance from small enclosures. 

Kef innovation

• Kef was founded on innovation and new technology.
• We are recognised in the history of loudspeaker development as one of the most important contributors and a great deal of our research has been published at well respected professional institutions, including the audio engineering society and the institute of acoustics.
• Kef's research legacy includes contributions from some of the greatest and most respected loudspeaker designers of the last five decades.
• Today, kef are the company to beat in computer analysis of loudspeakers. The software that we use to run our analyse is also used to power eighty-five percent of the world's super computers.
