Klipsch Heritage Loudspeakers

The Heresy III is the pound-for-pound champion of the world. Its compact size, traditional horn technology, luxury build and unrivalled lineage created a loudspeaker that delivers a smooth and dynamic sound with low-distortion. Easy to place because of their size, the Heresy III delivers a true audiophile performance regardless of what you throw at them.

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. The latest version also includes mid-range and tweeter compression drivers, as well as featuring a titanium diaphragm for smooth and accurate definition.

Nothing else on the market sounds as big or is as efficient as the Heresy III, given its relatively compact size. This model offers the greatest degree of placement flexibility of the Heritage Series. The bonus slant riser base can also be removed for cabinet installations.

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 a more aesthetically appealing and consistent appearance that is treasured more than any other cut of wood veneer.

Each 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. Each finished product is inspected and labelled with sequential serial numbers, ensuring that the Heritage Series speakers leave the factory as a meticulously crafted set.

While each and every component of the Heresy III 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. No other small speaker is built as well, or passed on to as many future generations, as the Heresy III.
