By using the same research and development used to create its professional cinema systems, Klipsch has developed the KL-525-THX LCR loudspeaker to create real theater-style sound in the comforts of home. As part of the THX Ultra2 family, this LCR reproduces all the passion that the filmmakers originally intended.

  • Sealed enclosure
  • Top-of-the-line internal wiring
  • Dual 5.25-inch Cerametallic woofers
  • 1-inch titanium diaphragm compression driver coupled to a 6- by 10-inch Tractrix Horn

The KL-525-THX is a THX Ultra2 certified loudspeaker designed primarily for front left-, center-, and right-channel reproduction in high-performance home theaters. It can also be used for surround channels, however, and is equally suitable for combination hometheater/music systems demanding superb sound and high output capability. Its sealed enclosure facilitates installation in custom cabinetry, and has back-panel threaded inserts compatible with OmniMount 60.0 Series wall/ceiling brackets.

The KL-525-THX design emerges directly from Klipsch’s experience as a leading supplier of cinema sound systems. A large, rectangular 90° x 60° Tractrix Horn raises the efficiency of the speaker’s 1-inch 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 combfiltering effects that afflict conventional multiple-tweeter solutions. And its dual 5.25-inch woofers have large, magnetically shielded motor structures that drive rigid, low-mass Cerametallic 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.

As the smaller of the two LCR speakers in the Ultra2 family, the highly efficient KL-525-THX features a sealed enclosure, top-of-the-line internal wiring, dual 5.25-inch Cerametallic woofers and a 1-inch titanium diaphragm compression driver coupled to a 6- by 10-inch Tractrix Horn. The KL-525-THX enclosure has the same dado and rabbet construction used in Klipsch professional speakers ensuring cabinet integrity in suspended applications. The Omni-Mount suspension points on this loudspeaker facilitate wall or ceiling mounting using standard hardware. Available in a custom Galaxy black finish with an aluminum fascia, the KL-525-THX delivers dynamic audio experiences that draw listeners into the middle of live concerts and action packed movies.
