The Heresy IV features a 1-inch Titanium LTS tweeter and a 1.75-inch polyimide midrange compression driver, both mounted to Klipsch’s signature Tractrix® horns for dynamic, highly efficient, and precise sound reproduction.
A powerful 12-inch fiber-composite cone woofer anchors the low end, now significantly enhanced by a new, rear-firing Tractrix® port – a first for the Heresy line – delivering surprisingly deep and impactful bass extension. Its high 99dB sensitivity allows it to be driven effortlessly by a wide range of amplifiers. Encased in beautiful real wood veneer and including a slanted riser base for optimal floor placement, the Heresy IV offers a detailed, wide soundstage, making it perfect for discerning audiophiles seeking a blend of heritage, performance, and versatile placement.
