'Of all art, music is the most indefinable and the most expressive, the most insubstantial and the most immediate, the most transitory and the most imperishable. Transformed to a dance of electrons along a wire its ghost lives on. When KEF returns music to its rightful habituation, your ears and mind, they aim to do so in the most natural way they can... without drama, without exaggeration, without artifice.' - Raymond Cooke, KEF Founder


The KEF story is one rich in inspirational thinking, meticulous attention to detail, and above all, a passionate advocacy for the Art of Music! In 1961, former BBC Electrical Engineer Raymond Cooke set up shop on the premises of Kent Engineering & Foundry (from where the name KEF is derived) near Maidstone, England. Applying a high level of rigorous engineering while employing new materials and technologies, Cooke focused on developing new drive units and enclosures to create loudspeakers that would push the performance envelope further than ever before. In 1988, incorporating a new neodymium/iron/boron magnetic material (developed by NASA) with ten times the power of standard speaker magnets, the revolutionary KEF Uni-Q® was born. This major innovation allowed KEF engineers to make a tweeter small enough to mount at the acoustic heart of the bass unit coil, for the first time providing a single point source of sound so natural that listening to it, you'll think the musicians are right in front of you! This sound innovation also considerably enlarged the optimum listening area in any room — searching for that elusive acoustic 'sweet spot' is now a thing of the past. And with almost 30 years of continuous innovation and development, the Uni-Q® attains a level of sound quality simply not achievable by conventional speakers — outstanding acoustic clarity produced over the entire audio range. We're happy to offer you this state-of-the-art KEF Audio Collection at significant savings, just in time for the holidays!
