Klipsch RC-64 III Reference Center Channel Speaker at Vinyl Sound Toronto Canada

The RC-64 III is a 2.5-way sealed center channel speaker from Klipsch (Hope, Arkansas, USA), designed and assembled in America and available at Vinyl Sound in Toronto, Canada. 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.

Frequently Asked Questions

What is the Klipsch RC-64 III?

The Klipsch RC-64 III is a 2.5-way sealed center channel speaker from the Klipsch Reference lineup, featuring quad 6.5" Spun-Copper Cerametallic™ woofers on cast aluminum frames, a 1.75" titanium diaphragm compression driver, and a 6.25" square 90° x 90° compressed molded-rubber Tractrix® Horn. It delivers 99 dB sensitivity across a frequency range of 57 Hz to 24 kHz, handles 200W continuous and 800W peak at 8 ohms, and is available in Black Ash, Cherry, and Walnut furniture-grade wood veneer finishes. It is designed and assembled in Hope, Arkansas, USA.

How does the Klipsch RC-64 III compare to the RP-504C II or the RC-62 II?

The Klipsch RC-64 III is a full step above the Reference Premiere RP-504C II, which uses dual 5.25" Cerametallic™ woofers, a 1" titanium LTS tweeter, and a Silicon Composite Hybrid Tractrix® Horn. The RC-64 III employs a much larger 1.75" titanium compression driver, a 6.25" Tractrix® Horn, and four 6.5" woofers in a 2.5-way sealed bifurcated cabinet, delivering nearly 7 dB more sensitivity at 99 dB versus the RP-504C II's lower output and extending to 24 kHz versus 25 kHz. The RC-64 III is designed for large dedicated home theaters where the center channel must match Heritage Series or high-efficiency Reference floorstanding speakers at reference listening levels.

What is the 2.5-way crossover design and why does it matter for a center channel speaker?

The RC-64 III's 2.5-way crossover network uses two different crossover points: the inner pair of woofers operates full-range up to 1,000 Hz where the compression driver takes over, while the outer pair of woofers is attenuated at 1,400 Hz. This progressive rolloff of the outer woofers reduces horizontal lobing and off-axis interference as frequency increases, which is a particularly critical issue for wide center channel speakers. Without this attenuation, the outer woofers would create comb filtering artifacts at off-center listening positions, causing tonal inconsistency across the seating area. The 2.5-way design ensures that every listener in the home theater hears the same dialogue and center channel effects with the same tonal character.

What is the Cerametallic™ woofer and why does Klipsch use it in the RC-64 III?

Cerametallic™ is Klipsch's pinnacle woofer cone material, combining the surface rigidity and hardness of a ceramic anodized aluminum finish with a low-mass lightweight structure. The result is a cone that resists flexing and breakup at high excursion levels while maintaining accurate pistonic motion, producing minimal distortion even at the 800W peak power the RC-64 III is rated to handle. Cast aluminum frames support each woofer with maximum structural rigidity, eliminating the basket resonances that occur in stamped steel frame designs. In a four-woofer center channel operating at reference home theater levels, this combination of Cerametallic™ cones and cast frames is essential to maintaining low distortion across the center channel's dynamic range.

Can the Klipsch RC-64 III be used with the Klipsch Heritage Series speakers?

Yes, the Klipsch RC-64 III is one of the few center channel speakers with sensitivity high enough to match Heritage Series floorstanding speakers like the Klipschorn, La Scala, and Belle Klipsch, which typically measure 100 dB or higher in sensitivity. At 99 dB, the RC-64 III comes within 1 dB of Heritage Series sensitivity, meaning it will match the dynamic output of Heritage floorstanding speakers without the center channel lagging behind the mains at high listening levels. This makes the RC-64 III the most appropriate center channel choice for Heritage-based home theater systems.

What amplifier power does the Klipsch RC-64 III require?

The Klipsch RC-64 III's 99 dB sensitivity and 8-ohm nominal impedance make it exceptionally easy to drive, reaching high output levels with as little as 10 to 20 watts of clean amplifier power. For reference-level home theater listening in large rooms, a dedicated center channel amplifier or AV processor with a high-current center channel output in the 100 to 200 watt range ensures full use of the RC-64 III's 800W peak handling capability. Common Toronto-area installations pair the RC-64 III with AV processors from Anthem, Marantz, and Denon driving dedicated multichannel power amplifiers from Anthem or Bryston.
