Heresy IV Floorstanding Speaker
A Little Heresy Is Good For The Soul.
Because of its size, the Heresy IV 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.
DESIGNED & MADE IN THE USA
The Klipsch Heresy IV speaker is a testament to the quality that Klipsch demands from each and every one of its audio products. Remember great sound? We do, too. The Klipsch Heresy enclosure is made in the USA, by proud craftsmen in Hope, Arkansas, just like Paul W. Klipsch (PWK) intended.
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 the input cup to crossover network to drivers.
