IV Floorstanding Speaker

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.

Even if you never turn them on, they are the first thing someone notices in a room — and when you do turn them on, their clean, crisp sound can impress even the most discerning speaker aficionados.

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.

Now with a rear port

For the first time in its long legacy, the Heresy now features a rear port – improving low-frequency extension by almost 10Hz, for room-filling bass. Utilizing Tractrix geometry, the all-new Heresy IV ports allow for the most efficient, fastest air transfer in their class, which reduces port noise for punchier low frequencies. Klipsch Tractrix ports have custom designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass.
