Heresy III Floorstanding Speaker
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.
A Little Heresy Is Good For The Soul
Introducing the pound-for-pound champion of the world. Whether it's for your burgeoning vinyl collection, home theater or whatever.
Nothing rocks harder. Period.

Made In Usa. Made To Rock.
Proudly handcrafted in Hope, Arkansas for over 50 years, the Klipsch Heresy III speaker is a testament to the quality Klipsch demands from each and every of its audio products.
Here's to 50 more years of Heresy.

They said he couldn't But he did it anyway
When PaulW. Klipsch was developing a smaller speaker for use between two Klipschhorns, an acquanintance declared that he couldn't possibly introduce it to the public because it was in direct violation of the corner horn principles, and amounted to acoustic heresy.
"The hell I can't" Mr. Klipsch said."And that's exactly what I'm going to call it!"
A year later the Klipsch Heresy loudspeaker was introduced and, iroinically, it became a bestseller in the church sound reinforcement market.

Today's Heresy
In 1985, we 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.
