Product Overview
Designed & Assembled in the USA
With cabinetry that is proudly 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. A year later the Klipsch Heresy loudspeaker was introduced and, ironically, it became a bestseller in the church sound reinforcement market.
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.
Power. Detail. Emotion.
PWK’s dream lives on in every legendary Heritage loudspeaker we make. Built to last a lifetime, each high-performance, handsomely crafted speaker will bring joy to your home for decades to come.
