Klipsch Heresy IV Overview
Because of its size, the Heresy offers the greatest degree of placement flexibility in the Heritage series. First introduced in 1957, this three-way horn-loaded loudspeaker is still able to deliver the awe-inspiring Klipsch sound that our fans around the world know and love.
COMPACT, THREE-WAY LOUDSPEAKER The Heresy was originally introduced in 1957 with a compact three-way design utilizing 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.
DRIVERS 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.
NETWORK The Heresy IV has been completely revoiced from its predecessor, utilizing premium componentry in an all-new high-fidelity network — minimizing 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.
TRACTRIX® PORTS For the first time in its long legacy, the Heresy now features a rear port – improving low-frequency extension by almost 10Hz, for room-filling bass. Utilizing Tractrix geometry, the all-new Heresy IV ports allow for the most efficient, fastest air transfer in their class, which reduces port noise for punchier low frequencies. Klipsch Tractrix ports have custom-designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass.
BI-AMP INPUT PANEL AND BINDING POSTS The Heresy’s premium, aluminum input panel accommodates large, high-quality speaker cables. Strong, versatile, and quality binding posts provide the capability for bi-wiring or bi-amping. The quality continues with Audioquest Type 4 with Star-Quad Geometry internal wiring featuring carbon-loaded insulation, nitrogen-injected PE and solid long-grain copper conductors ensuring the purest signal transfer from input cup to crossover network to drivers.
