Klipsch RC-64 III Center channel speaker

The flagship center channel in the Klipsch Reference lineup, it is built around quad 6.5" Spun-Copper Cerametallic™ cone woofers on cast aluminum frames, a 1.75" titanium diaphragm compression driver mated to a 6.25" square 90° x 90° compressed molded-rubber Tractrix® Horn, and a 99 dB sensitivity rating with a frequency response of 57 Hz to 24 kHz. It handles 200W continuous and 800W peak at 8 ohms, uses a sealed bifurcated acoustic suspension enclosure, and is finished in furniture-grade wood veneer available in Black Ash, Cherry, and Walnut. Every RC-64 III is assembled by skilled craftsmen in Hope, Arkansas, to the same exacting standards Paul W. Klipsch established when he founded the company in 1946.

Redesigned 90° x 90° Tractrix® Horn and 1.75" Titanium Compression Driver

The defining acoustic element of the RC-64 III is its redesigned 6.25" square 90° x 90° Tractrix® Horn, which introduces a key geometric refinement over previous generations: a circular horn throat paired to a square horn mouth. This transition geometry improves phase coherency from the compression driver at the throat through to the horn mouth, reducing phase-related coloration and improving high-frequency extension to 24 kHz. The compressed molded-rubber construction of the horn body adds controlled high-frequency damping that reduces horn resonance and harshness, producing a cleaner and more natural upper frequency character than rigid horn materials. The 1.75" titanium diaphragm compression driver carries a redesigned phase plug that further improves phase coherency at the throat of the horn, resulting in more accurate sound pressure linearity at high frequencies and greater dynamic clarity throughout the center channel's critical dialogue and mid-frequency range.

Quad Cerametallic™ Woofers, 2.5-Way Network, and Bifurcated Sealed Cabinet

The RC-64 III uses four 6.5" Cerametallic™ cone woofers, each mounted in a heavy-duty cast aluminum frame for resonance-free operation. Cerametallic™ is Klipsch's pinnacle driver cone material, combining exceptional surface rigidity with low mass to resist cone flexing and breakup at high excursion levels, producing minimal distortion even at the 800W peak power the RC-64 III is rated to handle. The 2.5-way crossover network is a sophisticated design that attenuates the two outer woofers' contribution at higher frequencies, reducing horizontal off-axis interference and lobing artifacts that cause tonal inconsistency at listening positions that are not centered directly in front of the speaker. This ensures a wide and even sound distribution so every listener in the home theater receives the center channel dialogue and effects exactly as intended. The sealed bifurcated MDF enclosure provides tighter and more accurate bass transient response than a ported design, extending to 57 Hz with no port noise or placement restrictions near rear walls or cabinetry.

Designed and Assembled in Hope, Arkansas

The RC-64 III is part of the Klipsch Reference lineup that is designed and assembled in the company's Hope, Arkansas facility, the same location where Paul W. Klipsch built his first legendary horn-loaded speakers in 1946. Every RC-64 III is constructed to the rigorous quality and consistency standards that Klipsch maintains for its American-built products, including furniture-grade wood veneer finishes that bring a premium, domestic aesthetic far above standard vinyl-wrapped speaker cabinets. The RC-64 III is available in Black Ash, Cherry, and Walnut veneer finishes, each with satin-painted baffles, making it a statement piece as well as a high-performance audio component.

Key Features

• Redesigned 90° x 90° Tractrix® Horn with Circular Throat: Circular-to-square horn geometry improves phase coherency and high-frequency extension to 24 kHz; compressed molded-rubber construction adds high-frequency damping to reduce harshness and improve detail.
• 1.75" Titanium Diaphragm Compression Driver: New phase plug design improves phase coherency at the horn throat, resulting in improved sound pressure linearity at high frequencies and cleaner, more natural dialogue reproduction.
• Quad 6.5" Spun-Copper Cerametallic™ Woofers: Four Cerametallic™ cone woofers on heavy-duty cast aluminum frames combine exceptional rigidity with low mass for minimal cone breakup, distortion, and resonance across the bass and lower midrange.
• 2.5-Way Network Crossover: Sophisticated crossover attenuates the outer woofers at higher frequencies to minimize horizontal off-axis interference and lobing, ensuring wide and even sound distribution across the entire listening area.
• Sealed Bifurcated Cabinet: Acoustic suspension enclosure provides tighter, more accurate bass transient response than ported designs and allows placement flexibility close to rear walls or within custom cabinetry.
• Bi-Wire and Bi-Amp Capable: Dual binding posts support bi-wiring and bi-amplification for advanced high-performance installation configurations.
• 99 dB Sensitivity: Exceptional efficiency means the RC-64 III matches dynamically with high-sensitivity Heritage and Reference floorstanding speakers with ease, and reaches high output levels with modest amplification.
• Furniture-Grade Wood Veneer Finishes: Available in Black Ash, Cherry, and Walnut, each with satin-painted baffles, elevating the RC-64 III well above standard speaker cabinet finishes.
• Designed and Assembled in the USA: Built by skilled craftsmen in Hope, Arkansas to the rigorous quality standards established by Paul W. Klipsch, ensuring long-term reliability and sonic consistency.
