More Information



Founded in 1961 by ex-BBC electrical engineer Raymond Cooke OBE, KEF was initially headquartered in a Nissen Hut on the premises of Kent Engineering & Foundry (from where the name KEF is derived), a metal-working company on the banks of the River Medway, near Maidstone in Kent.

From the very beginning, the pioneering inventiveness of KEF loudspeakers was undeniable and now for several decades, audiophiles around the world have revered KEF for their innovative, high-performance, beautiful loudspeakers.
