Klipsch Heresy IV Floorstanding Speakers Black Ash (pair)

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
