Group 4 Cantata (1965-70)

This model was originally designed for the Group 4 integrated High Fidelity Equipment and was later made available separately. The slim-line cabinet, designed by the Wright and Connor team, was strikingly different from the usual run of 'little boxes’ and its appearance matched the fine performance. Finished in selected Teak veneer with brushed antique silver trim and lustre black grille fabric.
 
Interior arrangements were similar to those of the Celeste, employing the B139 and T15 drive units with a printed circuit board crossover network. The somewhat larger enclosure giving a noticeable improvement in bass response as one would expect, the middle and high frequencies maintaining the delicate transparency characteristic of the KEF range of speakers.
