Klipsch Heresy IV

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, aluminium 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.

NETWORK

The Klipsch Heresy IV has been completely revoiced from its predecessor, utilising premium componentry in an all new high-fidelity network — minimising 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.

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 labelled with sequential serial numbers, ensuring that your Heritage series speakers leave the factory as a meticulously crafted set.

BUILT TO LAST

While each and every component of the Heresy IV is built to last. Klipsch has always recognised 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 have 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.

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.

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.
