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.

A Little Heresy is Good for the Soul
The Heresy IV is 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.
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.
Designed & Assembled in the USA. Made to Rock.
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.
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.
In addition to delivering smooth, dynamic and low distortion sound, the Heresy IV is available in a high-quality Natural Cherry, Distressed Oak, American Walnut, or Satin Black Ash wood veneer finish. A slant riser base is included for floor placement that can be removed for cabinet installations.

An awesome easy listen, very warm non-fatiguing sound, perfect for my desktop setup.
Playing Tidal on a MacBook Air into an IFI Zen Dac V2 and Vienna Acoustics Hayden Jubilee speakers, built like a tank with plenty on tap for near field listening or a small to medium size room.
This is a 5 star reviewed floorstanding speaker replacing my old 2005 speakers. The Dali Oberon 5 is excellent value and sound is pure and clean from a relatively small tower. I am enjoying running the speakers in and listening to hi-res audio with absolute clarity. E-piphany service is as always tops.
After much research I decided to purchase the Sennheiser 4 Momentum headphones and it is the best sounding and most comfortable headphones I've ever owned. I would highly recommend this item to any audiophile who appreciates brilliant audio quality. Excellent service delivery by Andre in delivering within the promised timeframe. I will definitely buy again.
