Klipsch KL-650-THX-R Ultra2 THX Certified Right Channel Bookshelf Speaker

The KL-650-THX is a THX Ultra2 certified loudspeaker designed primarily for front left-, center- and right-channel reproduction in large, ultimate-performance home theaters. It can also be used for surround channels, however and is equally suitable for combination home-theater/music systems demanding superb sound and high output capability. Its enclosure is front-ported to facilitate installation in custom cabinetry and has back-panel threaded inserts compatible with OmniMount 60.0 Series wall/ceiling brackets.

The KL-650-THX design emerges directly from Klipsch’s experience as a leading supplier of cinema sound systems. A large, rectangular 90 x 60deg. Tractrix Horn raises the efficiency of the speaker’s 1″ titanium-dome compression driver tweeter and optimizes its radiation pattern.

The horn enables the speaker to meet THX Ultra2 directivity specifications without the lobing and comb filtering effects that afflict conventional multiple-tweeter solutions. And its dual 6.5″ woofers have large, magnetically shielded motor structures that drive rigid, low-mass Cerametallic anodized-aluminum cones for high output and low distortion.

Construction is to the highest standard, with a professional grade rabbet and dado locked panel cabinet and premium components throughout to ensure sonic purity, consistency and reliability.
