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. The Heresy IV offers unparalleled sound quality from a relatively small speaker. It's quite possibly the speaker champion of the world. Whether it’s for your burgeoning vinyl collection, home theater or whatever, the Heresy IV will knock your socks off. What they say is true—a little Heresy is good for the soul.

Made to rock
Designed & assembled in the USA
With cabinetry that has been proudly built to order and handcrafted in Hope, Arkansas for over 50 years, the Klipsch Heresy IV 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 Paul W. Klipsch was developing a smaller speaker for use between two Klipschorns, an acquaintance 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, ironically, it became a bestseller in the church sound reinforcement market.
