Klipsch RP-404C II Overview

Outfit your home entertainment system with the ability to produce clear and natural vocals with the Reference Premiere RP-404C II 2.5-Way Center Channel Speaker from Klipsch in an attractive walnut finish. This second-generation Reference Premiere speaker utilizes a larger Tractrix horn size for the 1" titanium LTS vented tweeter, and 70% larger voice coils in the four 4" Cerametallic cone woofers. The result is a larger soundstage with increased power handling and more accurate directivity in the sound it produces.

90 x 90° Silicon Composite Hybrid Tractrix Horn
Klipsch's proprietary Tractrix geometry in the horn is specifically crafted to efficiently transfer the high frequencies of the tweeter to the listener. This second-generation Tractrix horn is larger for better directivity and a wider overall soundstage. The Tractrix horn can accomplish this level of audio fidelity and smooth frequency response by being combined with a phase plug and a compressed molded silicon face.
LTS Titanium Diaphragm Tweeter
Part of Klipsch's Reference line, the LTS (Linear Travel Suspension) works to minimize distortion for more detailed audio reproduction.
Vented Tweeter Design
The housing of the tweeter in this center-channel speaker clarifies the high-frequency signal by reducing standing waves that would otherwise create unwanted harmonics.
Cerametallic Woofers
Another signature aspect of Klipsch's Reference Premiere speakers are the Cerametallic woofers. This center speaker is equipped with four 4" woofers, and the Cerametallic construction keeps them lightweight, yet rigid, to both maximize acoustic efficiency and minimize distortion. In the second-generation, voice coils are 70% larger in diameter to ensure flawless reproduction with better power handling, cone control, and linearity. The addition of aluminum shorting rings adds to the improved power handling and lower distortion, while the motor structure itself improves the transit response while adding more control, both faster and with improved accuracy.
Sealed Design
The shallow depth of the speaker gives you the option of mounting it in-wall. The shallowness prevents bass-loading against a back wall in tighter spaces, while still projecting clear and easily understandable vocals.
Improved Input Panel
The RP-404C II features audiophile-grade wiring and easily accessible aluminum binding posts for any connection type.
Premium Construction
Klipsch uses internally braced furniture-grade MDF for a durable and attractive appearance. The walnut vinyl finish includes satin-painted baffles that have a scratch-resistant coating.
Magnetic Grille
You have the option of exposing the copper-colored woofers or to cover them up with a discrete speaker grille that attaches to the front of the RP-404C II magnetically.
Cork Pads
Replacing typical rubber bumpers are cork pads, which work to protect the surfaces of a stand or table.

Klipsch RP-404C II Reviews

Damaged, And…

By David
Rated 2 out of 5

The Item Came Out Of The Box, Which Was Fully Intact, Damaged, So Obviously From The Factory. I Asked Customer Service If They Were The Correct People To Handle A Warranty Issue, And Ralph From Customer Service Was Quite Rude About Informing Me He Would Not Be Helping. He Went As Far As To Tell Me Not To Even Bother Calling The Manufacturer. Fortunately Klipsch Was Nicer About It And Is Processing A Warranty Claim About It. The Speaker Looks And Sounds Fantastic Other Than The Dent. I’ll Definitely Buy The Brand Again But I’m Reconsidering Whether I’ll Buy From B&H Again After That Response.

Good center channel

Just what I needed for on my mantle. Main selling point was the sealed box. Blends in great with my other Klipsch speakers. Only had it a week, I’m still in the setup phase since I have several other new components. Happy with my purchase !
