VenmoChecking if any interest Iconic Klipsch Heresy II a three-way, high-efficiency floorstanding speaker produced between 1985 and 2005. As the second iteration of the legendary Heresy line, it introduced several design changes, including a shift to front-mounted drivers and different cabinet materials, while maintaining the signature horn-loaded sound.
Drivers: Features a 12-inch fiber-composite woofer (K-24-K), a 1.75-inch phenolic diaphragm midrange compression driver (K-53-K), and a 1-inch polyetherimide diaphragm tweeter (K-76-K). Efficiency: Highly sensitive at 97 dB (1W/1m), meaning they can be driven by low-wattage amplifiers. Frequency Response: Rated at 50 Hz to 20,000 Hz (±3 dB). Enclosure: A sealed (acoustic suspension) design constructed primarily from MDF (Medium Density Fiberboard), unlike the original plywood Heresy. Dimensions: Approximately 21.4" H x 15.5" W x 13.25" D and weighing about 37 lbs each. Performance and Sound Signature The Heresy II is widely regarded for its "live" and dynamic presentation, though it has specific characteristics noted by experts: Midrange Focus: Reviewers on YouTube and Pink Fish Media highlight its exceptional clarity in vocals and jazz, attributing this to the horn-loaded midrange. Bass Response: While described as "clean and tight," users on Reddit frequently note a lack of deep low-end (sub-bass), often recommending a subwoofer for full-range performance. Amplifier Pairing: Experts from the Klipsch Audio Community emphasize that these speakers pair exceptionally well with tube amplifiers, which can smooth out potential harshness sometimes found with certain solid-state equipment. Placement: They are designed to be floor-loaded (placed directly on the floor or a low riser) to optimize bass response.
