KLIPSCH RF-7 III
Description:
The Klipsch RF-7 III floorstanding speaker is a testament to the quality that Klipsch demands from each and every one of its audio products, designed and made in the USA by proud craftsmen in Hope, Arkansas.
Featuring a new 1.75" titanium diaphragm compression driver with an optimized phase plug design, a redesigned 90° × 90° circular-to-rectangular Tractrix horn with compressed molded rubber construction, and dual 10" spun-copper Cerametallic woofers with heavy-duty cast aluminum frames, the RF-7 III delivers the highest efficiency in its class.
Designed with a dual-chambered bifurcated enclosure, dual rear-firing Tractrix ports, bi-wiring/bi-amping capabilities, and furniture-grade wood veneers (Black Ash, Cherry, Walnut), this speaker represents the pinnacle of high-performance audio engineering.
Features:
New 1.75" Titanium Diaphragm Compression Driver: Features a new phase plug design to improve phase coherency at the throat of the horn, resulting in improved sound pressure linearity at high frequencies.
90° × 90° Tractrix Horn: Utilizes a circular horn throat paired to a square horn mouth to improve high-frequency response and extension while enhancing imaging and dynamics. Compressed molded rubber construction adds high-frequency damping to reduce harshness.
Spun Copper Cerametallic Woofers: Two 10" exceptionally rigid and lightweight cones providing minimal cone breakup, distortion, and highest-in-class efficiency when paired with the Tractrix horn.
Dual Chambered Enclosure Design: Bifurcated enclosure allows each 10" driver and port to work independently, improving linearity and minimizing standing waves that cause midrange frequency anomalies.
New Tractrix Ports: Dual rear-firing Tractrix geometry allows for the most efficient air transfer from the cabinet for the cleanest, most powerful low frequency response.
Cast Frame Woofer Design: Heavy-duty cast aluminum frames ensure resonant-free operation, incorporating a dual shorting-ring magnet structure for improved cone movement linearity.
Bi-Wiring / Bi-Amping Capability: Dual input terminals separate high and low frequencies into separate cables to reduce intermodulation distortion.
Furniture Grade Wood Veneers: Crafted with premium furniture-grade wood veneers available in Black Ash, Cherry, and Walnut finishes.
