Description
The Klipsch Heresy IV represents a complete sonic reimagining of an iconic three-way horn-loaded design. Its newly engineered crossover network employs premium components and steep-slope topology derived from legendary Heritage models, delivering superior efficiency and power handling with minimal signal degradation. The innovative rear-mounted Tractrix ports extend bass response by nearly 10Hz while their custom-flared geometry minimizes turbulence and port noise for articulate, room-filling low frequencies. The aluminum input panel and quality binding posts support bi-wiring and bi-amping configurations for flexible system integration. Compact enough for versatile placement yet powerful enough to command any listening space, the Heresy IV upholds seven decades of Klipsch heritage—meticulously crafted in Hope, Arkansas with the uncompromising standards Paul W. Klipsch established.
