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.

Part of Klipsch’s Reference line, the LTS (Linear Travel Suspension) works to minimize distortion for more detailed audio reproduction.

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.

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.

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.

The RP-404C II features audiophile-grade wiring and easily accessible aluminum binding posts for any connection type.

Klipsch uses internally braced furniture-grade MDF for a durable and attractive appearance. The ebony vinyl finish includes satin-painted baffles that have a scratch-resistant coating.

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.

Replacing typical rubber bumpers are cork pads, which work to protect the surfaces of a stand or table.
