🎯 High-Frequency Clarity with Hybrid Tractrix® Horn

The RP‑404C uses a 1” Titanium Linear Travel Suspension (LTS) tweeter, which reduces distortion and improves transient response. It’s paired with a 90° x 90° Hybrid Tractrix® horn, which directs sound more precisely into the listening area while minimizing unwanted reflections from walls and ceilings.

This horn-loaded tweeter setup is key to the Klipsch sound signature: clean, natural, and highly detailed — ideal for reproducing voices with pinpoint clarity and realism. From whispers to shouts, every bit of dialogue stays crisp and intelligible, even at low volumes.

🔊 Four Cerametallic™ Woofers for Deep Midrange Punch

Below the tweeter, the RP‑404C is equipped with four 4” Cerametallic™ woofers, designed for speed, stiffness, and accuracy. These spun copper drivers are lightweight yet rigid, ensuring low distortion and consistent midrange reproduction.

By using four smaller woofers instead of two larger ones, Klipsch delivers tight, focused mid-bass and excellent vocal presence without taking up excessive vertical space. This makes the RP‑404C perfect for placement below a TV or projector screen while still achieving large-scale audio performance.

---

🔊 Power and Sensitivity for Every System

The RP‑404C is rated at 125 watts RMS and 500 watts peak power, with a sensitivity of 95 to 97 dB. This means it can achieve room-filling volume levels with minimal amplifier power. Whether you’re running it with a mid-range AV receiver or a dedicated amplifier, you’ll enjoy dynamic range and headroom with minimal distortion.

This speaker also pairs perfectly with Klipsch’s other Reference Premiere models, ensuring tonal consistency and matched sensitivity throughout your entire surround sound setup.

🌀 Rear Tractrix® Port for Clean Bass Extension

While the RP‑404C is primarily focused on mids and highs, it doesn’t neglect bass. The rear-firing Tractrix® port is precisely tuned to extend low-frequency response without muddying dialogue or introducing port noise.

This ported design ensures the speaker can reproduce male voices, baritone instruments, and low-end effects with weight and definition — especially when placed near a wall or mounted in a cabinet with proper breathing space.

---

🧱 Premium Construction & Finish

Constructed from high-density MDF and internally braced, the RP‑404C minimizes cabinet resonances that could color the sound. Its seamless magnetic grille offers a sleek, tool-free option for aesthetic preferences, while the scratch-resistant veneer finish (available in Ebony, Walnut, or Piano Gloss Black) allows it to blend into modern living spaces or match your existing Klipsch components.

Every design choice—from the flared horn to the copper drivers—is both functional and stylish, maintaining the Reference Premiere’s reputation for audio and visual sophistication.

📐 Compact Yet Powerful Form Factor

Despite its quad-woofer layout, the RP‑404C maintains a low-profile horizontal design that’s perfect for TV stands, wall shelves, or under-screen placement. Measuring just over 26 inches wide and under 6 inches tall, it’s easy to integrate into most setups without blocking screens or interfering with decor.

And with its 28 lb weight, the speaker offers substantial acoustic authority while remaining easy to position or reposition during setup.
