  • Two 5.25-inch Cerametallic™ woofers
  • Dual 5-inch square Tractrix® Horn tweeters
  • Top-of-the-line internal wiring

The KS-525-THX produces a smooth, seamless, broad distribution of sound by employing a pair of 5.25-inch Cerametallic™ woofers and dual 5-inch square Tractrix® Horn tweeters in a Wide Dispersion Surround Technology array. WDST is the industry's no-compromise approach to surround speaker design because it offers both rich, immersion surround sound and precise localization of individual effects from a speaker that has much more placement flexibility than conventional designs.

This surround's sealed enclosure has the dado and rabbet construction used in Klipsch professional speakers, ensuring cabinet integrity in suspended applications. The Omni-Mount suspension points facilitate wall or ceiling mounting using standard hardware.

Available in a custom Galaxy black finish with an aluminum fascia, the KS-525-THX also utilizes top-of-the-line internal wiring to help listeners experience the true impact and exhilaration of surround sound.
