🔊 Titanium LTS Tweeter with Hybrid Tractrix® Horn

The RP‑504C uses a 1″ Linear Travel Suspension (LTS) titanium tweeter to deliver ultra-clean high frequencies. This tweeter design minimizes distortion and adds greater transient response to your soundstage. Paired with the Hybrid Tractrix® Horn, it produces highly controlled and directional high frequencies, sending sound precisely where it’s needed — toward your ears, not off your walls or ceiling.

The vented tweeter housing eliminates standing waves, further refining the speaker’s clarity. The result? Crystal-clear vocals, sibilance-free highs, and unmatched intelligibility across a wide listening area.

🌀 Four Cerametallic™ Woofers for Midrange Impact

At the heart of the RP‑504C are four 5.25″ spun copper Cerametallic™ woofers that bring a commanding presence to the midrange. These cones are ultra-light yet rigid, which allows them to move fast and cleanly — essential for reproducing natural vocal tones and midrange effects without distortion.

Unlike smaller or dual-woofer center channels, the quad-driver configuration offers more surface area, greater output, and smoother response. This makes the RP‑504C ideal for high-output applications and large cinematic spaces where strong dialogue projection is essential.

📈 Power Handling & Efficiency

With a 150W RMS and 600W peak power handling, the RP‑504C is designed to match high-powered AV receivers or amplifiers in dedicated home theaters. And thanks to its impressive 97 dB sensitivity, it delivers thunderous output levels without straining your amplifier.

This combination of power and efficiency makes the RP‑504C an excellent match for Klipsch tower speakers such as the RP‑8000F or RP‑6000F, ensuring balanced performance across your front soundstage.

---

🧱 Cabinet & Build Quality

The speaker cabinet is constructed from high-quality MDF with internal bracing, offering a rigid, non-resonant structure that enhances sonic purity. The rear-firing Tractrix® port improves airflow and deepens low-frequency extension, making sure that vocals and dialogue have body and depth without muddying the sound.

Its finish options — Ebony, Walnut, and Piano Gloss Black — are both durable and aesthetically refined. The magnetic grille attaches seamlessly to the front panel, giving you the choice between a clean, modern look or a bold display of the copper drivers.
