Because of its relatively "compact" size, this model offers the greatest degree of placement flexibility in the Heritage Series line. First introduced in 1957, the Heresy, a three-way design, started out as a compact center channel speaker to accompany the Klipschorn in three-speaker stereo arrays.

n 1985, Klipsch made some changes and improvements to this model and re-released it as the Heresy II. Today, the new Heresy III has a more powerful woofer, a bi-wire network, and a titanium diaphragm tweeter with a larger magnet assembly. The midrange compression driver also features a new titanium diaphragm.

In addition to delivering smooth, dynamic and low distortion sound, the Heresy III is available in a high-quality cherry, walnut or black ash wood veneer finish. Included is a slant riser base for floor placement that can be removed for cabinet installations.
