Klipsch KS-525-THX Ultra2 THX Certified Surround Speakers

The KS-525-THX is a THX Ultra2 certified surround loudspeaker designed for high performance 5.1, 6.1 and 7.1-channel home theaters. It is a great choice for any home theater or home-theater/music system that demands superior sound and high output capability. The speaker’s compact sealed enclosure maximizes installation flexibility. Integrated into the back-panel are vertically aligned keyholes for wall mounting as well as threaded inserts compatible with OmniMount 20.0 Series wall/ceiling brackets.

The KS-525-THX uses Klipsch Wide Dispersion Surround Technology (WDST), which enables it to deliver a unique combination of diffusion and coverage, yielding the benefits of both diffuse and direct radiating surround speakers with the drawbacks of neither. Listeners enjoy the deep, enveloping surround sound field characteristic of diffuse-radiating designs together with the precise localization of specific effects typically provided only by direct-radiating models.

The WDST array comprises two 1″ titanium-dome compression driver tweeters loaded by 5″ square 90 x 60deg. Tractrix Horns and two 5.25″ Cerametallic cone woofers. Each woofer/tweeter set is on an angled baffle facing opposite the other, with the tweeters on a diagonal to one another to minimize interference between their outputs. The tweeter is the same as used in the KL-650-THX and KL-525-THX LCR speakers and the woofer is the same as used in the KL-525-THX, ensuring a seamlessly cohesive sound field from front to rear. Construction is to the highest standard, with premium components throughout to ensure sonic purity, consistency and reliability.
