A LITTLE HERESY IS GOOD FOR THE SOUL

Because of its size, the Heresy offers the greatest degree of placement exibility

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 AND MADE IN THE USA

USING DOMESTIC AND IMPORTED COMPONENTS

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.

FEATURES

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 denition.

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-delity network — minimizing electrical degradation throughout the circuitry — for truer to life sound with best in class efciency 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 rst time in its long legacy, the Heresy now features a rear port – improving low frequency extension by almost 10Hz, for room lling bass. Utilizing Tractrix geometry, the all new Heresy IV ports allow for the most efcient, fastest air transfer

in their class, which reduces port noise for punchier low frequencies. Klipsch Tractrix

ports have custom designed inner ares 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.

FEATURES

HIGH EFFICIENCY

Nothing in the industry sounds as big or is as efcient as the Heresy, given its relatively compact size. This model offers the greatest degree of placement exibility 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 nished 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.
