Pair of KEF Concerto

Vintage British Monitors

If you’ve never heard a pair of these before then you’re in for a treat. These sound fabulous, with amazing & effortless bass extension provided by the B139 bass drivers, accurate mid-band from the B110 Bass/Mid drivers and sweet, sweet treble from the T27 tweeters.

The cabinets themselves are good and solid, with some surface blemishes in line with their age (see close-up pictures).

The following from the excellent KEF museum website:-

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and serious enthusiasts, the Concerto became a major success and remained in production until 1977 when it was superseded by the Cantata.
