KEF has been at the forefront of loudspeaker design and technology for 50 years. Its technical expertise and innovative designs grace anything from discrete Custom Install Ci speakers to multi-award winning home theatre systems and class-leading, serious Hi-Fi stereo speakers. From 1961 KEF has been one of the most forward thinking and technologically advanced Hi-Fi manufacturers in the world.
The results are plain to see, in long lists of breakthroughs that no other manufacturer can match - and Kef have the patents and academic papers to prove it. Right from the start, Kef pioneered the use of synthetic materials for diaphragms and driver surrounds to maintain consistent sound quality across the frequency range.
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. Such pioneering work allowed Kef to match pairs of speakers to within half of a decibel, for near-perfect stereo reproduction.
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 Kef to engineer a tweeter small enough to mount at the acoustic centre of the bass unit voice coil so that both acted as one. The resulting wide dispersion characteristics meant that the previously elusive 'sweet spot' was no more.
Innovation is what sets KEF apart. It's a remarkable legacy that informs everything Kef do to this day. Innovation is a continuing process, not a destination – and KEF still leads the way.
