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.

HIGH EFFICIENCY
Nothing in the industry sounds as big or is as efficient as the Heresy, given its relatively
compact size. This model offers the greatest degree of placement flexibility of the
Heritage series. The bonus slant riser base can be removed for cabinet installations.
MATCHED PAIRS
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 labeled with sequential serial numbers, ensuring that your Heritage series
speakers leave the factory as a meticulously crafted set.
BOOK-MATCHED WOOD VENEER
Klipsch only uses book-matched wood veneers for the Heritage series. The veneer
leaves are kept in order as they are delicately sliced from the timber and precisely
arranged to provide a mirror image at the splice joint — like turning the pages of a
book. This gives each speaker an aesthetically appealing and consistent appearance
that is treasured more than any other cut of wood veneer.
BUILT TO LAST
While each and every component of the Heresy IV is built to last. Klipsch has always
recognized 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 has 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.
