In the 1930's, Klipsch founder Paul W. Klipsch began exploring the possibility of reproducing the sound of an orchestra in his home. From the boom of a bass drum to the tinkle of a triangle, his challenge was to design a loudspeaker that would reproduce the force, as well as the subtleties of a live performance. The solution came in the form of a technology used for years in movie theaters and concert halls. Horn technology, and Paul's resulting design, the legendary Klipschorn, offered an unequaled combination of high sensitivity, wide dynamic range, low distortion, smooth frequency response and powerful bass. For 50 years, the Klipschorn's unique character and accurate sonic reproduction have made it unrivaled in the industry: its vintage design houses technology that is as relevant today as it was in the 1930's. Building the world's best sounding speakers Klipsch engineers are known for their smart, consumer-conscious designs. This Heritage Series speaker is just another example of Klipsch's extensive experience in consumer electronics. Heresy II is a three-way system that features sealed bass enclosure, horn loaded mid and high frequency drivers, and the following drive components: K-76-K tweeter; K-53-K midrange and K-24-K 12" woofer.
