Klipsch Heresy III
Floor-standing speaker (Heritage Black)
Our take on the Klipsch Heresy III by Crutchfield's Dave Bar
Classic Klipsch sound that never goes out of style
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.
A modern take on a time-honored design
Since that day long ago, Klipsch has tweaked and fine-tuned their 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. Klipsch also added dual speaker inputs to allow bi-wiring or bi-amping for even greater performance levels. And they increased the Heresey'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.
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. Each speaker is available in a beautiful Cherry, Walnut, or Black Ash lacquered wood veneer finish, and includes an angled riser base for floor placement that can be removed for custom installations.

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).

Why did you buy this?
The Crutchfiield advisor [ James Sep 17, 2017 ]
I was impressed by the history of the Heresy III. The size is right for set up that I have and the size of the room. Reviews were very favorable by other purchasers. Scratch and dent price helped along with Crutchfield's guarantee and the warranty on speakers. Assistance available by Crutchfield's service department. Also, it is a Klipsch. [ Richard Apr 19, 2017 ]
The Klipsch name and Quality. The sound is hard to beat for the price [ Joe Jul 23, 2016 ]
I have a pair of klipsch gen 1's bought in 1975 [ Juanita and Joh Jan 01, 2016 ]
I have a pair of Heritage II's that I bought in 1986. They are the only piece of audio equipment I haven't replaced in the last 30 years, or even thought about replacing. When I was looking for speakers for another room I looked at several brands and didn't see anything that looked better than the Heresies, so I got another pair. [ lewis Aug 18, 2017 ]
TOP RATED SPEAKERS / SLIGHT DISCOUNT [ ANTHONY Jun 06, 2017 ]
Klipsch and Crutchfield...an unbeatable combination [ Timothy P. Slon Aug 04, 2016 ]
AWESOME SPEAKERS [ RICKEY Jul 12, 2016 ]
I've owned Klipsch KG4's (that I re-capped and replaced the tweeter diaphragm) for the last few years and have been happy with them. But the cabinets look like crap and they are only two way (sometimes the mids can get muddled). I've always wanted to own a pair of Heresy's and finally talked myself into the purchase. [ Christopher Apr 18, 2016 ]
MADE IN U.S.A. [ C Mar 20, 2016 ]
Sound and quality workmanship. Listened to speakers on several occasions and was impressed by their sound and clarity. Crutchfield Product Rep Adam's assistance was very helpful. Adam's Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=39 [ JOHN PAUL Feb 02, 2016 ]
I chose this based on Crutchfield customer reviews and other professional reviews found on the internet. [ Dale Jan 15, 2016 ]
I purchased my first pair of Heresey 2 speakers in 1986,Saebo, Japan. I have had to do work on both. One of them can not be repaired so time for a new one. I push them with a 10 watt tube amp. Beautiful [ Nathan Van Dec 13, 2015 ]
Owned a pair a couple of decades ago and loved them. [ Will Nov 29, 2016 ]
I upgraded to a MA5200 last year and decided to upgrade from my 35+ year old Avid speakers. I had always thought the Klipsch Hereseys were much bigger than my old speakers. Come to find out they're almost the same size. They even look alike. Not even my wife will know what I've done! Crutchfield has always been a reliable source with knowledgeable advisors. Now we'll see if I can hear the difference. [ Steven Jan 30, 2018 ]
I like Klipsch [ Alan Nov 28, 2017 ]
I have always wanted them and I need some very efficient speakers for a tube amp. [ Ronald Apr 22, 2017 ]
My favorite speaker of all time. I always liked these for years. [ David Mar 14, 2017 ]
These are a 50th birthday gift for my twin brother. He will love them and their overall design. A timeless classic. I cannot wait to hear them. [ Michael Sep 03, 2016 ]
Setting up a separate monaural system for my mono LPs. I wanted a 12" speaker similar to what studios used in the 1950s and '60s and one that could be driven with a 25 or so watt tube amp. [ Kenneth Aug 08, 2016 ]
7 questions already asked
Don't know. I have three different, separate playback systems, one stereo, one mono which uses the Klipsh, and one 14 speaker and dual subwoofer surround sound system. They are all in different rooms. I have found that both crossover and volume settings on subwoofers will depend on the size/shape/acoustic deadness of the room, the placement of the subwoofer, the power of the subwoofer amp and the "speed' or musicality of the particular sub. In short, yo do it by ear and personal taste. [ Kenneth Dec 24, 2016 ]
I would set to large if your processor doesn't let you set frequency. Mine Lexicon allows me to set the front L/R crossover to a fixed frequency. I would look at what Large vs small means via frequency on your system. Also these are acoustic suspension speakers and they reproduce the low frequencies a little different than a ported sub-woofer. You want a good amount of overlap or you will be missing some of the upper lows. [ Turbo Dec 24, 2016 ]
I set mine to large they have a great base sound [ BRIAN Dec 23, 2016 ]
If you can set crossover at 150hz. Set up as large speaker. [ SCOTT Dec 23, 2016 ]
It is still 8 ohms [ Mark Nov 06, 2015 ]
Hi John, i'm sorry i do not have a clue, i would e-mail Klipsch and ask them. Joe [ Joe Nov 06, 2015 ]
It's my understanding that each amp in a biamp configuration would still the speaker as an 8 ohm load...HF amp 'sees' 8 ohms and LF amp 'sees' 8 ohms. [ Barry Nov 06, 2015 ]
Thanks for your question. For information on selecting the best amp I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy Apr 29, 2016 ] Staff
1 answer Hi, I keep reading that, as a rule of thumb, I should buy an amplifier that has at least 50% more power than the 100 W rating for the heresy IIIs. I have also read reviews stating the, because of the high efficiency of the Heressy IIIs, amplifiers rated at 60 W RAM or 80 W RAM are plenty to make them sound amazing... can you offer any comment s and give me some direction? [ Luis Dec 04, 2015 ]
Luis C , I have the heresy III and run them on a pair of paramount 300B tube amps at only 8 watts per channel and they sound amazing . You'll be fine with the amps your looking at. [ ricky Dec 04, 2015 ]
No it does not. I used my receiver [ Scott May 15, 2018 ]
No, these speakers have just the normal two wire binding posts. Properly placed, you may find you don't need a sub. Mine are mounted in a very unorthodox manner and I do have a powered sub but the connection for it comes our of the amplifier. [ Steven May 06, 2018 ]
Not to my knowledge. I have heard that historically Klipsch do not need a lot of power to drive them. They were a gift to my brother and the backs have the bi-wire posts only. Nothing for a sub. [ Michael May 06, 2018 ]
Yes, but these are very heavy, most bookshelves would stress with these on them. [ James Feb 07, 2018 ]
No. Sorry [ CHIKAO Jan 31, 2018 ]
Yes they can be used as a bookshelf speaker. You can remove the angled base if needed for mid height use (for proper angle). I use them in my studio along with other speakers (you know A-B-C comparisons). [ Alan Jan 30, 2018 ]
Yes. But be aware the Heresy is LARGE and HEAVY to be considered a bookshelf speaker. [ Kenneth Jan 30, 2018 ]
Yes, the bottom incline base can be unscrewed... thus the logo on the grill turned. Regards MF [ Cesar Jan 30, 2018 ]
Does this thing have a Sub Out if required in future ? [ augustya May 06, 2018 ]
The Speakers should sound fine but in my opinion they are really best with two channel audio. Seems like a waste to have them muddied up with surround sound. I have used mine both on floor and with stands. I currently have them up on Bose 301 stands. But, I use two separate sub woofers, one for each channel, when they are on the stands....they loose "punch" once they are elevated. The Herritage line of Klipsch speakers are really meant for 2 channel audio...hope this helps ;) [ Jeffrey Nov 06, 2017 ]
If you are going to use them mostly for home theater,on the floor will be fine. If you use them for stereo listening ,put them on a 20 inch stand or heavy wood base ,it will shine on in the air with your favorite music. You could even put them on about a foot high base with the angle feet in place and have a wonderful sound too I have owned many speakers of all costs and contours.I will never part with my heritage speakers. Or my cornwall ONES .They go in the will. And i prefer them to my RF 7 11 s !!!!!! [ Chuck Nov 02, 2017 ]
These speakers sound great as the main speakers in a home theater surround sound system. I placed them in a bookshelf system about 2 inches off the floor. As main speakers, I don't think there is any need to raise the speakers any higher and I would not place them at ear level, although I do have your levels speakers as surrounds. [ Donald Nov 02, 2017 ]
Hi Lewis. I purchased a set of these speakers back on June. I use them everyday and they produce the highest quality sound beyond anything I dreamed possible. I use for mainly music but I feel they would capture all the sound levels you would ever experience. The highs and lows and the deep bads are incredible in these speakers. I started with mine on the floor but raised them about 2 feet off the floor and wow, even better sound. Approaching ear level does make a difference. Hope this helps you make a choice.
