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.
