The Klipsch Reference Premiere RP‑504C features a 90° x 90° silicone composite hybrid Tractrix® horn that maximizes efficiency, enhances detail, and directs high frequencies toward the listening area, with a phase plug and molded silicon face ensuring smooth, natural sound. Its Linear Travel Suspension (LTS) titanium diaphragm tweeter minimizes distortion for detailed performance, while the vented tweeter design reduces standing waves for clearer high‑frequency reproduction. Signature spun‑copper Cerametallic™ woofers deliver rigidity, low distortion, and high efficiency, working in tandem with the horn‑loaded tweeter for class‑leading performance. Tractrix ports use specialized geometry and custom inner flares to enable fast, efficient air transfer with reduced turbulence and cleaner, more powerful bass. Robust single 5‑way screw terminals support banana plugs or 12‑gauge bare wire for flexible and reliable connections. The speaker is offered in ebony, walnut, and piano gloss finishes, with satin‑painted baffles on vinyl models and hand‑sanded, mirror‑like surfaces on the piano gloss version. A strong, flexible magnetic grille provides an elegant, removable design, while copper anodized trim rings, cast aluminum feet, satin baffles, and a laser‑etched logo complete the premium modern aesthetic of the Reference Premiere II series.
