When Klipsch introduced the original Heresy in 1957, there wasn't another speaker like it. And that's still true for their latest-generation Heresy IV.

Vintage looks and clean, dynamic sound


Use a pair of the Heresy IVs for sweet stereo sound in your listening room.

When Klipsch introduced the original Heresy in 1957, there wasn't another speaker like it. And that's still true for their latest-generation Heresy IV.

Over the years, Heresy's clear, low-distortion sound has been a hit with our customers. The previous-version Heresy III earned dozens of glowing reviews from listeners with a broad range of musical tastes.

Updated, innovative design

For the Heresy IV, Klipsch once again tweaked this classic design, going with a new polyimide-diaphragm midrange driver. And the tweeter gets an all-new wide-dispersion phase plug, which creates a larger listening "sweet spot."

For the first time, the Heresy now features a rear port, which improves low-frequency extension by about 10Hz for more authoritative sound.

Heresy's high-efficiency design — 99 dB sensitivity — makes it an excellent choice for use with low- and medium-powered tube amps. 

Proudly made in the USA

The Heresy IV is designed and hand-built in Hope, Arkansas. It's available in several attractive book-matched wood veneer finishes, which provide a "mirror" image of each other. 

That's because each pair of Heresys is sourced from the same piece of timber, with the speakers precisely arranged to provide an aesthetically pleasing mirror image at the splice.

Bi-amp or bi-wire for the best performance

Each speaker comes equipped with two pairs of speaker inputs for bi-amping or bi-wiring. Since they don't include any speaker wire, consider reading our article on choosing and installing speaker wire to find the best option for your system.
