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
Sound quality.
The right headphone discharges very quickly, loses its connection with the device, freezes. Reloading does not help.
Pros: good sound quality. Mobility. The appearance and equipment of the device.
A large minus: the right headphone is discharged very quickly, loses its connection with the device, freezes. Reloading does not help.

Original reviews
Paul W. Klipsch believed four principles to be the foundation for great sound. They continue to drive the design of every new Klipsch speaker, today and tomorrow: High Efficiency / Low Distortion Klipsch horn technology is highly efficient, providing more accurate sound with less power and less distortion – resulting in louder, cleaner audio. Klipsch’s Law: Efficiency is inversely proportional to distortion. Controlled Directivity Klipsch horn technology accurately directs sound to the proper locations, which, in turn, creates a more lifelike soundstage without wasting acoustic energy where sound is not needed or desired. Wide Dynamic Range The softest sounds are reproduced with remarkable clarity and the loudest sounds are delivered without harshness or distortion – with the greatest possible range between the softest and loudest sounds. Flat Frequency Response Audio is delivered without frequency bias – no unnatural highs, mids or lows – reproducing recorded sound as accurately as possible without colorization.
