Reference Series Model 103/3 (1986-93)
Improving on the redoubtable Model 103.2 was no easy task, for this compact and refined two-way loudspeaker, much admired for its accuracy, ruggedness and consistency, had enjoyed great popularity among domestic and professional users for many years. But technology and techniques advance steadily, and the 103-sized performance package had been considerably improved.
Model 103/3 was a three-way system incorporating KEF’s unique coupled cavity bass loading method, and its own version of the KEF KUBE low-level equaliser. The combination of these two design elements provides unusually extended low frequency response and exceptional power handling.
