KEF Reference Series Model 90 Center Speaker -

Reference Series Model 90 (1993-98) Model 90, along with the acclaimed Model 100, was one of the first genuinely high quality centre channel loudspeakers to appear on the world market. Key to its success was the Uni-Q driver array – with its broad and uniform dispersion pattern it ensured that listeners seated away from the central position will still hear clear and intelligible dialogue that was routed to the centre of the screen. The use of Reference Series components guaranteed that the sound quality was of the highest level and accurate timbre matching with, primarily with Models 101/3 and 102/2, ensured that an integrated and high performance home theatre system could be easily achieved. With a dark grey enclosure, black grille-cloth and curved side panels it perfectly complemented the appearance of the high performance video equipment of the time.
