Never before has Klipsch offered such premium performance in an in-wall speaker. You’ll discover it delivers effortless dynamic range and brings superior sound to larger rooms thanks to its highly regarded THX Select2 certification.  

The KL-6504-THX employs four high-output 5.25-inch fiberglass woofers for powerful bass impact, while a 1-inch titanium tweeter mated to a new symmetrical pattern 90 x 90 square Tractrix® Horn generates flat in-room frequency response with high efficiency and low distortion. This exclusive horn design also allows the speaker to consistently deliver unbeatable sound, whether it’s installed horizontally or vertically.

The KL-6504-THX’s titanium horn-loaded tweeter is mated to the woofers using precision-voiced, high-definition crossover networks, creating high sensitivity. This makes the speaker easier to drive, so it requires a lot less amplification power than conventional designs.

Adding to its first-class sound, the KL-6504-THX also has a premium look and feel with its grille off, featuring a deluxe MDF baffle with aluminum fascia. But when covered, the speaker’s paintable grille allows it to blend in perfectly with any home décor. All-new sure-grip mounting dogs offer even pressure against drywall for long-term installation reliability.

Furthermore, the KL-6504-THX comes with a lot of options. It is timbre matched to all of our THX-certified products, so you can mix and match for the discreet stereo or home theater system that’s just right for you.
