Description
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.
| Includes New 10-Year Warranty |
| All-new K-702 midrange compression driver, featuring a polyimide diaphragm, for exceptional detail |
| For the first time, the Heresy IV features a rear port for the most efficient, fastest air transfer in their class, which reduces port noise for punchier low frequencies |
| K-702 midrange is mated to the K-704 Tractrix® horn for a wide coverage pattern |
| K-107-TI titanium diaphragm high-frequency driver with an all-new wide dispersion phase plug for providing exceptionally even high-frequency dispersion |
| All-new high fidelity network for truer to life sound, best-in-class efficiency, and power handling |
| 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 |
| Available in a high-quality Satin Black Ash, Distressed Oak, or American Walnut wood veneer finish |
| Designed & assembled in the USA |
