Concerto (1969 - 77)
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and remained in production until 1977 when it was superseded by the Cantata.
