klipsch heresy iv

about klipsch heresy iv

The legendary Paul Klipsch was one of the pioneers of Horn loudspeakers. His original Klipschorn dates back to the 1940s, and (with updates) remains in production to the present day. Any speaker still being made after more than half a century has to have something going for it. 

Because of its size, the Heresy offers the greatest degree of placement flexibility in the Heritage series. First introduced in 1957, this three-way horn-loaded loudspeaker is still able to deliver the awe-inspiring Klipsch sound that fans around the world know and love. 

 

 

 

features.

  • All-new K-702 midrange compression driver.

  • K-702 midrange is mated to the K-704 Tractrix® horn for a wide coverage pattern (Soundstage is very wide with the IV)

  • K-107-TI titanium diaphragm high-frequency driver with an all-new wide dispersion phase plug for providing exceptionally even high-frequency dispersion (More HF details over the III)

  • All-new high fidelity network for truer to life sound, best-in-class efficiency, and power handling

  • 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 (Bass is fast and super tight)

  • 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 Black Ash, Natural Cherry, Distressed Oak, or American Walnut wood veneer finish

  • Designed & assembled in the USA

what’s different from the heresy iii?

  • Wide dispersion HF phase plug versus the old standard one

  • K-702 polyimide diaphragm compression driver offers better clarity and dynamics, and is larger than the outgoing K-53 titanium driver

  • Modified Tractrix horn with Mumps technology for a smoother response, and better coverage over the K-701 horn

  • Steep-slope network with internal AudioQuest wiring

  • Now with a port. The Tractrix port offers tighter and faster low frequencies

  • Cosmetic upgrades include a scripted logo badge, brushed aluminum input panel, salt-and-pepper grille cloth, and improved finishes.

review. 

So what is new with the version IV over the III (that I loved so much) that actually makes an improvement to the speaker? THAT is the question as I am not big on buying the latest and greatest because it is simply the newest, and supposed best. These IV’s are even more real, more intense, closer, more tangible and defined with actual texture to voices in some recordings. With this newfound sound the old Version III’s sound darker in comparison. 

The Heresy IV is like an all new speaker, improved in every way over the III.

As it is now, I now own these Heresy IV as I could not move them from my room once I heard and settled in with what they gave me back in return. That was, so far, many deep nights listening to music that has touched my soul in the most direct of ways.
