About the Klipsch Heresy III
Classic Klipsch sound that never goes out of style
Classic Klipsch sound that never goes out of style
The name "Heresy" pretty much sums up Klipsch's whole approach to their business: they are not a company to play it safe or play by the rules. This speaker has a sound all its own that our customers seem to love (just check out some of the glowing reviews).
The very first Heresy speakers were introduced to the world in 1957. Since then, Klipsch has tweaked and fine-tuned this classic design to create the Heresy III. A more powerful woofer, large-magnet titanium diaphragm tweeter, and new titanium diaphragm midrange compression driver all work together to give this speaker a thoroughly up-to-date sound, housed in a cool, decidedly vintage-looking design.
Klipsch also added dual speaker inputs to allow bi-wiring or bi-amping for even greater performance levels. And they increased the Heresy's already high-efficiency design by 3 dB to an impressive 99 dB — making them an excellent choice for low- and medium-powered tube amps.
Made in the USA
Just about the only thing that hasn't changed is the quality. Klipsch still makes the Heresy one at a time by hand in Hope, Arkansas. It comes in a range of gorgeous finishes, and includes an angled riser base for floor placement that can be removed for custom installations.
Notes from a former Crutchfield audio guru
"I'll never forget the first time I heard the Klipsch Heresys. It was by sheer coincidence. A college housemate had shown up at the door with a pair of them that he'd brought from home. Even way back then their design was over 20 years old, and they looked more like antiques than audio gear to me. Confident that my own then-up-to-the-minute and highly rated bookshelf speakers were more than a match for these 'elder statesmen,' I invited my housemate to hook them up for a listening session (and a little lesson in humility, heh heh)."
"But I was the one who was taken to school that day. The instant we fired up the Heresys I was speechless. Their sparkling clarity and dynamic range were on a level that my speakers could never touch. All the musical details came pouring out loud and clear in ways I'd never heard before. And although I never told him, I was totally envious. Many years later I can't even remember Chris' last name, but I'll never forget the sound of those Heresys and the lasting impression they made on me."

Heresy III: First introduced in 1957, the Heresy started life as a compact center channel speaker for the Klipschorn in three-speaker stereo arrays. The Heresy is a compact, three-way design that uses horn-loaded compression drivers for midrange and treble reproduction and a direct radiating 12"woofer for the low frequencies.
3-Way Design: The Klipsch Heresy III loudspeaker features a three-way design that uses horn-loaded compression drivers for midrange and treble reproduction, plus a direct radiating 12" woofer for the low frequencies.
- 1" Tweeter (w/ Tractrix Horn): The 1" (K-107-TI) titanium diaphragm compression driver is coupled to a Tractrix Horn for smoother high-end response with greater extension, enhanced imaging, and more powerful dynamics.
- 1.75" Midrange (w/ Exponential Horn): The 1.75" (K-53-TI) titanium diaphragm compression driver is coupled with an Exponential Horn for detailed, accurate midrange sound.
- 12" Woofer: The 12" (K-28-E) fiber-composite cone woofer delivers powerful low frequencies. The 12" woofer also employs a treated cloth surround for added efficiency and flexibility.
Crossover Network: For signal purity and perfect driver integration, the crossover (HF: 5500Hz/MF: 850Hz) on the Heresy III features the finest components and Klipsch custom internal wiring.
MDF Enclosure: The Klipsch Heresy III loudspeaker employs a solid, inert MDF cabinet which minimizes panel vibrations that can color sound. The acoustic suspension (sealed) design lends itself to the speaker's accurate, natural sound reproduction. The Heresy III is available in a high-quality cherry, blonde cherry, walnut, or black ash real-wood veneer finish.
Dual Binding Post Speaker Terminals: The Klipsch Heresy III loudspeaker has two sets of binding posts connected by jumpers. Using the dual binding posts, you can bi-amp or bi-wire the speakers. The binding post terminals will accept banana plugs (single/dual), pin-connectors, spade-connectors, and bare wire.
Placement: The Klipsch Heresy III loudspeaker will perform well in a variety of locations. Corner, floor placement will deliver the highest degree of low bass reinforcement and the pre-installed slant riser base helps to compensate for the Heresy's short stature. This riser may be removed for shelf or cabinet placement. Self-stick rubber pads are supplied for attachment to the bottom of the cabinet to prevent scratching of shelves and hard surfaces. Best results will be achieved using the following general guidelines.
- Place on a common wall 6' to 15' apart and position them equidistant from the wall behind the speakers.
- Angle speakers toward the listener and even with or forward of any adjacent obstructions.
- Placing them near a corner or wall provides the greatest amount of bass while moving the speakers away from room boundaries reduces bass.
- Asymmetrical placement of a pair of speakers from adjacent side walls can smooth room-induced bass unevenness.
Note: Experiment with the above guidelines to suit your taste and to compensate for your room's acoustic characteristics.
Heritage Series (Made in the USA): The Klipsch Heritage Series is built and handmade in the USA at Klipsch's manufacturing facility in Hope Arkansas. Each Heritage Series loudspeaker utilizes Klipsch proprietary horn-loaded technology to bring a live music listening experience into the home. All Heritage Series loudspeakers are available in a variety high-quality wood veneers. Paul W. Klipsch believed four principles to be the foundation for great sound. They continue to drive the design of every new Klipsch speaker, today and tomorrow.
- High Efficiency & Low Distortion: Klipsch horn technology is highly efficient, providing more accurate sound with less power and less distortion - resulting in louder, cleaner audio. Klipsch's Law: Efficiency is inversely proportional to distortion.
- Controlled Directivity: Klipsch horn technology accurately directs sound to the proper locations, which, in turn, creates a more lifelike soundstage without wasting acoustic energy where sound is not needed or desired.
- Wide Dynamic Range: The softest sounds are reproduced with remarkable clarity and the loudest sounds are delivered without harshness or distortion - with the greatest possible range between the softest and loudest sounds.
- Flat Frequency Response: Audio is delivered without frequency bias - no unnatural highs, mids or lows - reproducing recorded sound as accurately as possible without colorization.
Note: The Heritage Series consists of the La Scala II, Cornwall III, Heresy III, and Forte (all sold separately).
