Klipsch Heresy IV Floorstanding Loudspeaker

The Klipsch Heresy was originally introduced in 1957 with a compact three-way design utilising a 12” woofer and horn-loaded midrange and tweeter. In 2006, the Heresy III was upgraded with a more powerful woofer and a bi-wire network as well as midrange and tweeter compression drivers and features a titanium diaphragm for smooth and accurate definition.

The Heresy IV incorporates an all new K-702 midrange compression driver, featuring a polyimide diaphragm for exceptional detail and dynamics. The K-702 midrange is mated to the K-704 Tractrix® horn, providing you with a wide coverage pattern and smooth response throughout the listening area. The K-107-TI titanium diaphragm high-frequency driver features an all new wide dispersion phase plug, providing exceptionally even high-frequency dispersion throughout the listening area, making for a wider, more accurate sweet spot.

The Heresy IV has been completely revoiced from its predecessor, utilising premium componentry in an all-new high-fidelity network — minimising electrical degradation throughout the circuitry — for truer to life sound with best in class efficiency and power handling. The new network draws from the classic three-way steep slope design of the legendary Klipschorn, La Scala and Cornwall speakers.

Every pair of Heritage series loudspeakers is grain-matched, using wood veneer panels that come from the same timber. Each cabinet is carefully matched so that each speaker in the pair is practically indistinguishable from the other. The speakers move seamlessly together through the factory, and each finished product is inspected and labelled with sequential serial numbers, ensuring that your Heritage series speakers leave the factory as a meticulously crafted set.

While each and every component of the Heresy IV is built to last. Klipsch has always recognised the unique and critical role of a loudspeaker’s cabinet in the sound reproduction process. From the craftsmen in Hope, AR to the engineers in Indianapolis, IN, Klipsch have always put an extraordinary emphasis on cabinet design. The Heresy enclosure is assembled using only the highest-grade adhesives and fasteners. The riser base can be removed for cabinet installation or placement on optional stands.
