The Heresy was originally introduced in 1957 as 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, bi-wire network, as well as midrange and tweeter compression drivers, featuring a titanium diaphragm for smooth and accurate definition.

Limited Australian Walnut

Australian Walnut (also known as Queensland Walnut) is grown in the coastal tablelands of North Queensland, Australia. The species varies in color, but is usually a pale-golden hue highly contrasted with darker streaks of chocolate brown, grey, black or even pink. Australian Walnut grain is moderately close and even, and sometimes wavy, resulting in a wide variety of figure effects.

This wood will only be used on 70TH Anniversary Edition speakers.

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.

Each pair of Heritage Series loudspeakers are 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. Each finished product is inspected and labeled with sequential serial numbers, ensuring that the Heritage series speakers leave the factory as a meticulously crafted set.
