Our take on the Klipsch Reference Premiere RP-450CA by Crutchfield's Dave Bar
The ideal center speaker for your Dolby Atmos® home theater
If you're looking for the perfect partner to round out your Klipsch Dolby Atmos surround speaker system, then you've come to the right place. The powerful RP-450CA Reference Premiere center channel speaker will put you right in the front row for exciting cinematic sound. Its proprietary Klipsch speaker technologies are ideal for re-creating an immersive, high-impact Dolby Atmos listening experience. The RP-450CA features four 5-1/4" woofers for plenty of bass and midrange punch, plus Klipsch's signature Tractrix® horn tweeter for controlled sound dispersion, outstanding intelligibility, and sparkling clear highs. A gorgeous real wood veneer finish makes this center channel the ideal cosmetic match to the Klipsch Reference Premiere RP-280FA Dolby Atmos floor-standing tower, and an attractive addition to any home theater.
The Reference Premiere Series difference
Never one to rest on its laurels, Klipsch has been busy refining and improving its designs to create loudspeakers that blow the doors off of its loyal followers' expectations. The Reference Premiere Series builds on the acoustics and technologies of Klipsch's classic Reference Series, with important enhancements that provide even more intense home theater sound.
With its Hybrid Tractrix® horn and Cerametallic woofers, the RP-450CA center channel speaker is built to effortlessly deliver clear, powerful Klipsch sound. A real wood veneer finish gives it a luxurious look and feel.
Hybrid Horn technology for dynamic performance
Horn technology is one of Klipsch's long-standing hallmarks. Flared openings in the speaker cabinet project sound waves toward your listening area and prevent them from simply spilling out in all directions. This design reduces reflections that can color the sound, and boosts dynamics and efficiency for powerful sound that remains crystal-clear at all volume levels.
Klipsch's newly designed Hybrid Tractrix horn features a circular throat around an advanced titanium diaphragm tweeter that transitions into a square 90º x 90º mouth. This unique shape provides a cleaner, more efficient transition of sound waves into your listening space. Compared to previous Klipsch models, this horn design delivers a wider sweet spot with more precise placement of instruments and vocals. Even the horn material itself has been upgraded to molded silicone rubber that helps decrease resonance for smoother, warmer highs.
A horn that can enhance bass, too
Looking around the back, you'll find that instead of a conventional round port tube found on many speakers, Klipsch uses a Tractrix horn-shaped opening for smoother, more efficient airflow in and out of the cabinet. The resulting decrease in air turbulence makes for cleaner, more powerful bass with reduced port noise and low-frequency distortion.
High-tech woofer design
The RP-450CA's Cerametallic™ woofers dish out smooth midrange and articulate, well-defined bass. Klipsch makes its cones out of specially treated aluminum that's strong yet lightweight, to dampen and prevent distortion. With the Reference Premiere Series, Klipsch also gave these woofers newly developed titanium voice coil formers that allow more linear movement for enhanced efficiency, lower distortion, and extended low frequency response.

90° x 90° Hybrid Tractrix Horns: A redesigned Tractrix Horn utilizes a circular horn throat paired to a square horn mouth to further improve high-frequency response and extension, while enhancing imaging and dynamics. The compressed molded rubber construction adds high frequency damping to reduce harshness and improve detail. This creates the cleanest, most natural sound possible. These 90° x 90° Hybrid Tractrix Horns provide a wider sweet spot while maintaining controlled directivity of the sound.
LTS Tweeters: Behind each Tractrix Horn lies a 1" titanium tweeter with a linear travel suspension for open, natural, sound. The Linear Travel Suspension minimizes distortion for enhanced, detailed performance.
Cerametallic Woofers: The four 5.25" woofers of the RP-450CA center-channel loudspeaker feature Klipsch's distinctive, copper-colored Cerametallic material. Made with an anodized aluminum, this cone is strong and dent resistant. The anodizing process converts its inner and outer surfaces to ceramic. The outcome is a rigid cone with superb damping characteristics that will not flex or resonate at frequencies within the woofer's operating range The 5.25" woofers also employ a rubber surround for added durability.
Crossover Network: The Klipsch RP-450CA center-channel speaker's crossover network is constructed using extremely high-quality components including top-of-the-line internal wiring, polyester film-type capacitors and an air-core inductor to ensure signal purity and proper driver integration. The speaker's enhanced crossover frequencies (500/1500Hz) offer smoother on-axis and off-axis integration.
Bass Reflex MDF Enclosure: The Klipsch RP-450CA employs a bass reflex enclosure with a rear-firing Tractrix port for greater efficiency and bigger bass response. Utilizing Tractrix geometry, the all new Reference Premiere bass port allows for the most efficient, fastest air transfer from the cabinet for a clean, powerful low frequency response. The ported enclosure features a MDF cabinet finished with real wood veneers (black). The speaker's rigid cabinet offers improved internal cross-bracing to minimize panel vibrations that can color sound.
Magnetic Grille: The center-channel loudspeaker features a removable magnetic low-diffraction grille which easily snaps into place over its polymer front baffle.
Binding Posts: The Klipsch Reference Premiere series RP-450CA is equipped with sturdy binding posts to ensure a secure connection to many types of cable and connectors. The binding post terminals will accept banana plugs (single only), pin-connectors, spade-connectors, and bare wire.
Placement: The RP-450CA should be centered directly above or below your video screen. If necessary, you can place the speaker on an optional floor stand in front of and below the screen that elevates it to the correct height. Ideally, however, the speaker's front baffle should be flush with the front of the screen.
Rubber Feet: The center channel speaker comes with four self-adhesive rubber feet to secure the speaker in place and prevent any damage to your stand's or shelf's surface. The rubber feet add approximately 0.125" to the height of each speaker.

1 answer What really is the difference between the KLIPSCH RP-450C and the KLIPSCH RP-450CA - I know they say it is "optimized for Atmos" but how so? Also: It bothers me that you are not answering this question online. Seriously? Just spell it out in black and white... I'm a big boy, I can handle it!!! [ SD Jul 30, 2016 ]

The Klipsch Reference Premiere RP-450CA center speaker is an ideal match for the Klipsch Reference Premiere RP-280FA tower speakers, both cosmetically and acoustically. If you're looking to install a 5.1.2 (5 surrounds + 1 sub + 2 Atmos speakers) Atmos system, then an Atmos-enabled receiver that's capable of 5.1.2 processing should be enough to suit your needs.
