Klipsch Cornwall IV Floorstanding Speaker (Each) at Vinyl Sound Toronto Canada The Cornwall IV is a three-way floorstanding loudspeaker from Klipsch (Hope, Arkansas, USA), available at Vinyl Sound in Toronto, Canada. Part of the legendary Klipsch Heritage series, the Cornwall IV delivers 102dB sensitivity, a 34Hz to 20kHz frequency response, and a 15-inch fiber-composite cone woofer, making it one of the most efficient and dynamically capable floorstanding speakers available. Hand-crafted in Hope, Arkansas with book-matched wood veneers and grain-matched cabinet pairs, the Cornwall IV represents over seven decades of Klipsch acoustic engineering. K-702 Midrange Driver and Tractrix Horn Technology The Cornwall IV introduces the all-new K-702 midrange compression driver, featuring a polyimide diaphragm for exceptional clarity and dynamic range across the critical midrange frequencies. The K-702 is paired with a modified Tractrix horn incorporating Klipsch's patented Mumps technology, which corrects polar response through the midrange band and ensures consistent, even sound dispersion across the full listening area. At the top end, a K-107-TI titanium diaphragm compression driver handles high frequencies above 5,000Hz, delivering effortless detail without harshness. The K-33-E 15-inch woofer manages bass duties, loaded into a bass-reflex enclosure via front-firing Tractrix ports engineered for fast, turbulence-free air transfer and reduced port noise. Revoiced Three-Way Network The Cornwall IV has been completely revoiced from its predecessor with an all-new high-fidelity crossover network using premium components selected to minimize electrical degradation throughout the signal path. The network architecture draws directly from the steep-slope three-way crossover topology used in the legendary Klipschorn and La Scala loudspeakers, with crossover points set at 700Hz and 5,000Hz. The result is best-in-class efficiency and power handling, with a continuous power handling of 100 watts and a peak capacity of 400 watts, and a maximum SPL of 119dB continuous. Heritage Craftsmanship and Cabinet Construction Every Cornwall IV cabinet is built in Hope, Arkansas using only the highest-grade adhesives and fasteners, and assembled from MDF with fine wood veneers. Klipsch uses exclusively book-matched veneers for the Heritage series, with veneer leaves sliced in sequence and arranged to create a precise mirror image at each splice joint. Grain-matched pairs ensure that both speakers in a set are visually and acoustically consistent, with sequential serial numbers applied after a final factory inspection. The Cornwall IV is designed to be a lifelong, generational loudspeaker. Key Features K-702 Midrange Compression Driver: New 1.75-inch polyimide diaphragm driver for detailed, dynamic midrange performance with low coloration. Mumps Tractrix Horn Technology: Patented horn geometry correction for even polar response through the midrange, providing consistent sound across the listening room. K-33-E 15-Inch Woofer: Fiber-composite cone woofer in a front-firing Tractrix bass-reflex enclosure for deep, controlled bass extension to 34Hz. 102dB Sensitivity: Exceptional efficiency allows the Cornwall IV to reach high SPL levels with low-powered amplifiers, including single-ended tube designs. Revoiced Three-Way Network: Premium crossover components in a steep-slope topology derived from the Klipschorn and La Scala, minimizing signal degradation. Bi-Wire and Bi-Amp Capable: Aluminum input panel with dual binding posts accommodates large speaker cables and supports bi-wiring or bi-amping configurations. Book-Matched Wood Veneer: Heritage series veneers are sliced and arranged in sequence for a mirror-image splice joint and visually consistent appearance. Grain-Matched Pairs: Both speakers in every Heritage pair are matched from the same timber and assigned sequential serial numbers after final inspection. Built in Hope, Arkansas: Every Cornwall IV is hand-assembled in Klipsch's original facility with craftsman-level attention to cabinet integrity and longevity.

The Klipsch Cornwall IV is a three-way floorstanding loudspeaker from Klipsch, hand-built in Hope, Arkansas, USA, featuring a 15-inch woofer, a 1.75-inch polyimide midrange compression driver, and a 1-inch titanium tweeter. It delivers 102dB sensitivity, a 34Hz to 20kHz frequency response, and a maximum SPL of 119dB, making it one of the most efficient full-range floorstanding speakers in its class. The Cornwall IV is part of the Klipsch Heritage series and is sold individually. How does the Klipsch Cornwall IV compare to the Klipsch La Scala AL5 or Forte IV? The Klipsch Cornwall IV sits between the Forte IV and the La Scala AL5 in the Heritage lineup. The Forte IV is smaller with a 12-inch woofer and passive radiator, while the Cornwall IV uses a larger 15-inch direct-radiating woofer in a bass-reflex cabinet for deeper bass extension to 34Hz. The La Scala AL5 uses a fully horn-loaded bass section for even higher sensitivity and dynamic contrast, but sacrifices some low-frequency extension. Compared to competitors such as the Focal Kanta No. 2 or Sonus faber Olympica Nova III, the Cornwall IV offers significantly higher sensitivity, making it the preferred choice for low-powered tube amplifier pairings. Can the Klipsch Cornwall IV be driven by a low-powered tube amplifier? Yes, the Klipsch Cornwall IV is ideally suited to low-powered tube amplifiers. Its 102dB sensitivity means that a single-ended triode amplifier producing as little as 2 to 8 watts can drive the Cornwall IV to realistic listening levels without strain. The 8-ohm nominal impedance is also a comfortable load for most tube amplifier output transformer designs. The Cornwall IV is widely used with amplifiers such as the Line Magnetic 508IA, Dennis Had Inspire, and Decware SE84UFO. What is Klipsch Tractrix horn technology? Tractrix is a proprietary horn geometry developed by Klipsch that follows a mathematically derived flare rate designed for the most efficient, lowest-distortion acoustic loading of a compression driver. A Tractrix horn expands rapidly near the throat and more gradually toward the mouth, which reduces internal reflections and improves high-frequency dispersion. The Cornwall IV uses Tractrix horns for both the midrange and tweeter, and Tractrix geometry in the bass-reflex port design to reduce air turbulence and port noise. What is Klipsch Mumps technology? Mumps is a patented Klipsch horn modification that adds small protrusions, or bumps, at the throat of a Tractrix horn to correct polar response through the midrange frequency range. Without Mumps, compression driver and horn combinations can exhibit uneven off-axis dispersion, causing inconsistent sound as listeners move around the room. On the Cornwall IV, Mumps is applied to the midrange horn to ensure that the K-702 driver produces even, consistent coverage throughout the listening area. Where can I buy the Klipsch Cornwall IV in Toronto or Canada? The Klipsch Cornwall IV is available at Vinyl Sound, an authorized Klipsch Heritage dealer in Toronto, Canada. Vinyl Sound carries the Cornwall IV in-store and online, with full Klipsch manufacturer warranty support for Canadian customers. The Cornwall IV is sold individually, allowing customers to configure mono or stereo pairs to their specifications. What amplifier power does the Klipsch Cornwall IV require? The Klipsch Cornwall IV has a continuous power handling of 100 watts and a peak handling of 400 watts, but its 102dB sensitivity means it performs exceptionally with amplifiers well below that ceiling. In practice, 5 to 50 watts from a quality tube or solid-state amplifier is sufficient for most listening environments. Klipsch recommends avoiding amplifiers with high levels of DC offset or excessive noise, as the Cornwall IV's high sensitivity will resolve amplifier background noise more readily than lower-sensitivity designs.
