KEF Concerto Loudspeakers
The Concerto, released in 1969, was KEF’s latest high quality three-way loudspeaker system. It maintained the KEF practice in high end systems of using a dedicated midrange driver to cover the critical vocal range, in this case the newly developed 5” bextrene coned B110. Together with the new T27 ¾” melinex domed tweeter and the established B139 bass driver, it offered full range reproduction with low distortion, high power capacity and wide dispersion.
Intended for professionals and serious enthusiasts, the Concerto became a major success and remained in production until 1977 when it was superseded by the Cantata.

We can never get enough of the original English KEF Concerto loudspeakers, they were magnificent back in 1969 and still are today! The Concerto’s are a classic loudspeaker, detailed sound quality and pure musical enjoyment.
