Overview

The Klipsch Reference Premiere RP-504C II is the flagship center channel speaker designed to be the undisputed anchor of your home theater. As the source of nearly 70% of a movie’s soundtrack, this speaker utilizes four 5.25" Cerametallic copper-spun woofers and an enlarged 90° x 90° hybrid Tractrix horn to ensure dialogue is never lost in the mix. The "MKII" generation features a 70% larger voice coil for greater control and a vented tweeter housing to eliminate harshness. It’s a high-output, low-distortion powerhouse that brings cinematic scale and front-row vocal clarity to any medium-to-large listening room.

Simcoe Audio Video Insight

In our experience outfitting theaters across Ontario, the center channel is the one place you should never compromise. The RP-504C II is the "problem solver" for rooms where dialogue often sounds muffled or overshadowed by sound effects. What makes this speaker special is its sheer surface area; with four woofers, it has the "heft" to make deep male voices sound rich and authoritative rather than thin. It’s the perfect tonal match for the RP-8000F II towers, creating a seamless "wall of sound" across the front of your room. If you want to stop riding the volume button during action movies, this is the speaker that makes it happen.

Best for the Klipsch RP-504C II: utilize the included cork pads on the bottom of the cabinet. These aren't just for surface protection; they provide essential mechanical decoupling from your media furniture. By reducing the transfer of vibration from the speaker to your console, you prevent the cabinet from adding its own "color" to the sound, which keeps dialogue sounding natural and crisp even at high volumes.

More Details

Why It Wins

• Quad-Woofer Authority: Four 5.25" Cerametallic woofers provide incredible power handling (600W peak) and a wide soundstage that anchors action directly to the screen.
• Enhanced Dialogue Focus: The new, larger silicone composite Tractrix horn focuses high frequencies toward the listeners, significantly improving intelligibility.
• Superior Build: The internally braced MDF cabinet and rear-firing Tractrix port work together to deliver punchy, fast bass without the distracting "chuffing" noise found in lesser ports.

What Makes It Different

The RP-504C II stands out due to its 2.5-way crossover design. Unlike standard speakers that can suffer from "interference" between multiple drivers, Klipsch carefully manages the frequency hand-off so the center channel behaves like a single, cohesive source. This minimizes the "lobing" effect often found in wide center speakers, ensuring that people sitting on the far ends of the couch hear the same clear dialogue as those in the "sweet spot." Additionally, the move to aluminum binding posts and audiophile-grade internal wiring ensures the cleanest possible signal path from your receiver.

Technical Highlights

• 1" Titanium LTS Vented Tweeter: A hallmark of the Reference Premiere line, reducing distortion and unwanted harmonics for lifelike high-frequency detail.
• 96dB Sensitivity: Extremely efficient, meaning it can reach cinematic volumes with ease, even when used with more modest AV receivers.
• Cerametallic Woofers with Faraday Rings: Updated motor structures improve transient response, allowing the speaker to keep up with fast-paced movie transitions.
• Premium Finish: Features a scratch-resistant vinyl finish with a satin-painted baffle and a sleek magnetic grille.

Alternative Options

The RP-504C II is our premier high-output center channel. If you have a smaller space or a narrower media console, the PSB Alpha C10 is a more compact, high-value choice that still offers excellent dialogue clarity. For those looking for a fully automatic vinyl experience to pair with their theater system, the Dual CS 429 provides a high-fidelity analog source. If you are building a system for a secondary room and want a simplified, all-in-one solution, the Sony BRAVIA Theatre Bar series is a convenient alternative.
