Klipsch RP-404C II Center Channel Speaker

Overview

A shallow media console or a fireplace mantle usually rules out a serious centre channel speaker, since most designs need several inches of rear clearance to sound right. The Klipsch RP-404C II solves that without giving up Reference Premiere performance.

The RP-404C II pairs a 1" titanium Linear Travel Suspension (LTS) tweeter with a larger 90° x 90° silicone composite hybrid Tractrix horn for crisp, detailed highs, and four 4" Cerametallic woofers for a rich, authoritative midrange. Unlike most centre channels, it uses a sealed enclosure rather than a ported one, so it can sit flush against a wall or inside a shallow cabinet without the bass-loading distortion a ported design would suffer in that spot.

At just 6.47" deep, it fits where deeper centre channels can't, and cork pads replace rubber bumpers for secure, vibration-damped placement on a mantle or shelf. Additional internal bracing minimizes cabinet resonance, and aluminum binding posts round out the input panel.

Simcoe Audio Video Insight

For Central Ontario clients mounting a TV above a fireplace or working with a shallow media console, the RP-404C II's sealed cabinet is the detail that actually solves the problem — most centre channels need breathing room behind them to avoid a boomy, muddy sound, but this one is tuned for tight placement from the start.

Why the Klipsch RP-404C II Stands Out

Shallow Sealed Cabinet Design

At just 6.47" deep, it fits flush against walls or inside shallow cabinets without bass-loading distortion.

Four Cerametallic Woofers

Four 4" woofers deliver a rich, authoritative midrange for clear dialogue.

Titanium LTS Vented Tweeter

Minimizes distortion and standing waves for detailed, clear highs.

Larger Hybrid Tractrix Horn

A 90° x 90° silicone composite horn improves high-frequency transfer into the room.

Cork Pads for Secure Placement

Replace rubber bumpers for secure, vibration-damped placement on a mantle or shelf.

Reinforced, Low-Resonance Cabinet

Additional internal bracing keeps vocals clear even at higher volumes.

Buyer's Guide

Who It's For

  • The Mantle & Console User: needs a high-performance speaker for a shallow shelf or fireplace mantle installation.
  • The In-Wall Candidate: wants a centre channel that fits into custom millwork or shallow wall cavities.
  • The Reference Premiere System Owner: wants a tonal match for RP-series towers or bookshelves without the depth of a standard centre channel.

How It Compares

The RP-404C II is Klipsch's shallow-depth solution within the Reference Premiere centre channel lineup. If you have the room for a deeper cabinet and want more low-end punch and a larger soundstage, the RP-504C II or RP-500C MKII are the natural step-up options within the same series.

Klipsch RP-404C II Center Channel Speaker FAQs

How does the Klipsch RP-404C II compare to a soundbar or a small center speaker in sound quality?

The RP-404C II uses four dedicated 4-inch Cerametallic woofers and a 1-inch titanium tweeter loaded into a 90° x 90° Tractrix horn, giving it more driver surface area and directed horn output than a compact soundbar or small center speaker. This translates into fuller, more natural dialogue reproduction with greater clarity in vocal performances.

What are the dimensions and weight of the RP-404C II, and how does its size affect placement options?

The RP-404C II measures approximately 5.72 inches in height, 26.85 inches in width, and 6.47 inches in depth, weighing around 20.3 pounds. Its shallow-depth cabinet allows for versatile placement, including mounting on walls beneath TVs or tucking into shallow media consoles and fireplace mantles, without compromising sound quality.

How does the RP-404C II's sealed cabinet design impact its placement near walls?

The RP-404C II's sealed (acoustic suspension) cabinet design minimizes bass distortion and allows for flexible placement near walls without adversely affecting sound quality. This feature is particularly beneficial for users with limited space or those preferring wall-mounted configurations.

Can the RP-404C II be paired with an AV receiver from any brand?

Yes. With a nominal impedance of 8 ohms and 125W continuous / 500W peak power handling, the RP-404C II pairs well with standard AV receivers from brands like Denon, Marantz, and Yamaha rated at 50 watts per channel or higher.
