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 60° square 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.
