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.
