KEF Celebrates 60 Years

The company promises a number of new products to be released during its 60th anniversary year.

As of October 2021, KEF has been creating award-winning speakers for six decades.

KEF is named after its original site — Kent Engineering and Foundry in Maidstone — where it continues to develop its products today. Established in 1961 by Raymond Cooke OBE, the BBC engineer was propelled by a love of music and refusal to compromise. Since its inception, KEF has existed to fill rooms with music as it was made to be heard and to move souls with truly authentic soundscapes. Over the years it has never lost sight of its British roots, uncompromising quality, or boundary-pushing innovations.

KEF pioneered the early use of synthetic materials and was the first company to use computer simulation to measure and develop speaker performance, followed by the creation of its disruptive Uni-Q, Uni-Core, and Metamaterial Absorption technologies. The original collection of high-fidelity speakers, architectural speakers, and subwoofers has evolved to include wireless speakers, portable Bluetooth speakers, and headphones.

With a team of talented engineers and in-house designers who work together to maintain the brand’s audio integrity, KEF has also partnered with the likes of Ross Lovegrove, Michael Young, Sir Terence Conran, Eric Chan, and Marcel Wanders to bring their unique perspectives to KEF’s product design.

KEF Today and Tomorrow

In this anniversary year, KEF says it will launch the most advanced products it has ever created — to be announced in the coming months —which will again push the boundaries of the listening experience, both at home and on the move.

October 2021 begins KEF’s 60th anniversary. For this special year, KEF has curated six playlists, selecting iconic British tracks that best represent each decade, which will be available to download and stream on Spotify, Tidal, and Apple Music.

This October, there will also be the opportunity for three music fans to hear sound as their favorite artists intended, entering to win one of three set of prizes: Mu3 Earphones with a KEF Gift Bag, Q350 Bookshelf Speaker pair with a Kube 10b Subwoofer, or a LS50 Wireless II system with a KC62 Subwoofer. Entrants simply need to fill out a short form before November 11 for a chance to enter.

Selected KEF Milestones

KEF has had many milestones over the past 60 years, here, Residential Systems spotlights a few highlights from each decade.
