Discover the legendary Klipsch sound and iconic mid-century design with the Heritage Heresy IV American Walnut Floorstanding Speaker Pair. Handcrafted in the USA, these speakers deliver powerful, efficient audio performance in a compact, room-friendly design.
The Klipsch Heritage Heresy IV features a three-way design with a 12-inch woofer, horn-loaded midrange, and horn-loaded tweeter. This combination produces dynamic, lifelike sound with exceptional clarity, detail, and impact across the frequency range. The updated K-702 midrange compression driver and wide-dispersion phase plug create a more open, natural, and precise soundstage, making vocals and instruments sound effortless and realistic.
For the first time in the Heresy line, the Heresy IV includes a rear-ported bass reflex enclosure that extends low-frequency performance, delivering deeper, tighter bass while maintaining control and musicality. With Klipsch’s renowned high sensitivity, these speakers can be easily driven by a wide range of amplifiers, including low-powered tube amps and high-quality solid-state gear.
The American Walnut real wood veneer cabinet is book-matched and finished to furniture-grade standards, ensuring a premium and visually unique appearance. The slant riser base angles the speaker for optimal listening height and dispersion, ideal for stereo listening rooms, living spaces, and dedicated home audio setups.
