Custom Series CR200F, CR250SW, CR160F, CR160Q

In 1987 KEF introduced two new products, CR200F and CR250SW, specifically designed for in-wall use, responding to the increased demand for unobtrusive yet high performance loudspeakers in the domestic environment. Although KEF had supplied loudspeaker assemblies for in-wall mounting from the 1960s onwards, with such models as the K1 and K2 baffles, this was the first excursion into the new Custom Install market with purpose built bezels for the cavity wall application. The range was supplemented in 1989 with the CR160F and CR160Q.
