For sale a lovely pair of KEF Concertos 3 way speakers. Three-way floor speaker system, using the famous T27 tweeters and KEF B110 mid & B139 bass drive units. They were both made on 25^th August 1972 so 52 years old. The previous owner bought them from new and I have only used them quietly. They are in very, very good condition please study the pictures. Heavy speakers like these often have smashed corners but these are in great shape. Following a friends advise I have fitted Falcon Acoustics Crossovers which do indeed “dramatically” transform the Concertos from good to amazing (cost £202), I have left the old crossovers in place as recommended by FA for aesthetic reasons but are not wired up. So imagine LS3/5As with sub woofers!
