KEF was founded in 1961 by a BBC engineer named Raymond Cooke. KEF is unique in the audio market with its scientific approach to speaker design. The company holds over 150 patents and each model has been built upon decades of sound research. The result is a speaker line that is unmatched in sound imaging with speaker 'sweet spots' that are multiples larger than competitors. The Lab highly recommends KEF's LSX Series speakers, in addition to KEF subwoofers.
