product description

Outfit your home entertainment system with the ability to produce clear and natural vocals with the Reference Premiere RP-504C II 2.5-Way Center Channel Speaker from Klipsch in an attractive ebony 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 5.25" Cerametallic cone woofers. The results are 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 general 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 5.25" 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.

Tractrix Ports

If you prefer a deeper bass from your center channel, the integrated ports of the RP-504C II utilize Klipsch's Tractrix geometry to product clean and punchy low-end frequencies. The geometry allows the air to quickly and efficiently exit the speaker, which also reduces port noise. Customized inner flares further lowers noise by reducing air turbulence entering the port.

Improved Input Panel

The RP-504C 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 ebony 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-504C II magnetically.

Cork Pads

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