KEF Speakers - KEF is a leading British innovator of high-end audio products. Founded by BBC engineer Raymond Cooke in 1961. KEF’s mission is to deliver sound with as little intervention as possible; from treble to bass, and everything in between. Listeners should be able to close their eyes and immerse themselves in the sound so deeply that they are transported, in their minds, to the source. Experience is everything, and that’s no overstatement.
