Because of its high power-handling capability and unusually high sensitivity, the RC-25 can sustain significantly higher output than most conventional center speakers — an important consideration, since the center channel typically carries about 60% of the total energy in a surround movie soundtrack. Yet the RC-25 requires only about half as much amplifier power as most competitors. High frequencies are reproduced by a 1-inch titanium dome compression driver tweeter. A 5-inch square 90° x 60° Tractrix® Horn molded into the front of the enclosure raises the driver’s efficiency and controls its radiation pattern to minimize detail-blurring reflections from walls, floor, and ceiling. Flanking the tweeter are twin 5.25-inch polymer frame, Cerametallic™cone woofers configured in a Tapered Array. Klipsch Tapered Array™ Technology operates both woofers at the lowest frequencies but only one all the way up to the point where the tweeter takes over, eliminating the destructive middle-frequency interference between woofer outputs characteristic of ordinary woofer-tweeter woofer lineups.
