Our take on the Klipsch Heresy III

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).

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.

Heresy iii

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.

Very Pleased

Craig from Oklahoma on 1/31/2019

Crutchfield Customer Review (What's this?)

Have had these speakers for roughly a month and am overall very pleased. The cabinet is the only thing I would change about them. The laminate chips easily even with minor bumps. Would have been great if Klipsch used a veneer instead. The overall sound though is very solid. Lows aren't overpowering and at times could use a bit more punch but the package is well balanced. Their size is another plus in my opinion. Big sound from a compact speaker that will fit where many wouldn't and the sound fills my living room very well. Overall I'm pleased with the Klipsch Heresy III - just be gentle with them.

Crutchfield customer from Batavia, IL on 1/9/2019

Crutchfield Customer Review (What's this?)

Little short on low end definitely need some kind of sub woofer but after break in they kick some ass and sound great Pretty sound for classical and strings

Pros: Small with a kick

Cons: Short on low end but I have 2 12 inch subs that help

Good speaker - in the correct application

Mike from Marietta, OH on 12/26/2018

Crutchfield Customer Review (What's this?)

These speakers have numerous features that are top-notch. The cabinets are solid and attractive. The small size fits well in a small to mid-sized room. They play middle to high frequencies better than any speaker I've tried out. The down side for me is the low-end. Yes, I read the spec sheet showing 58 Hz as the bottom of the frequency response, but the 12" woofer and the rave reviews convinced me to give them a shot. Listening to a David Gilmour guitar solo never sounded so crisp, clear. However, the Heresy's came up short when the solo was joined by what should have been a thumping drum beat. I was completely disappointed in the bass response. While trying to decide whether to replace the speakers or help them by supplementing with a powered sub, I came across an article on the Klipsch website titled 'History of the Cornwall'. The article begins with the following quote; "In 1957 Paul Klipsch had designed the Heresy speaker specifically to be a center channel between two Klipschorns." Now it all made sense. These speakers were never intended to be stars in my simple 2-channel setup. I returned the Heresy's and went looking for a more well rounded speaker. Perhaps it will serve those who follow me to know Paul Klipsh's design intent for the Heresy before making a decision.



Klipsch Heresy III

Crutchfield customer from Bailey, CO on 12/22/2018

Crutchfield Customer Review (What's this?)

These speakers rock! I am extremely satisfied with this purchase. They require a little break-in; mine were bright (too much treble) initially, but after several hours of use, the brightness is gone. The Heresys provide a clean, neutral wall of sound. They work well with all genres of music that I have feed them (rock, classical, country, blues, & jazz). My two channel system also serves as my sound system when watching movies... the Heresy speakers excel: dialog is _extremely_ clear, effects sound authentic (gun fire, explosions, etc.), and of course the actual soundtrack sounds great too. The Heresy III speakers have no major flaws. They sound great at all volumes. It is so easy to play these loud - no distortion; just a clear wall of sound. Bass is strong and controlled, but not as deep as you would think with the 12" woofer. Sound stage, and imaging are good. They have a high build quality, and are are very attractive. These speakers are actually bigger than they look in the marketing photos, but not obnoxiously large. They have a solid footprint, and are very stable. (I do not worry about my german shepherds knocking these over. The tower speakers my Heresys replaced are tall and thin, and were knocked over by my dogs on multiple occasions.)

Pros: Clear, accurate sound


Second pair fifty years later

Michael from Chicago, IL on 12/13/2018

I've had Klipsch Heresy speakers for 51 years - I was lucky and got my first pair in 1967, when I was 17 years old. They sounded great, though I had rather modest audio equipment: a Scott model 260 integrated amp and a Dual 1019 turntable. Now, after many equipment changes I've again purchased a pair of Heresies- this time with McIntosh turntable, preamp and the tube 275 amplifier. The new sound is truly superior - great tonal range, and a live sounding reproduction. I think they sound better than my $10k McIntosh XR100 speakers. I have them wired in such a way that I can make an instant A/B comparison. Don't get me wrong, both sets of speakers are great sounding, it's just that for the jazz music (1930-1967) the Klipsch have a definite edge. I purchased a pair in cherry, which I personally prefer to the original walnut. One important thing to note is that these speakers require a "burn-in" period to sound their best. I think it took over 100 hours for the speakers to sound their best. Don't get me wrong, they're great out of the box, but give them some time to get their full richness. You can't go wrong with these classic speakers - they're superb.

Pros: Wonderful full, rich sound. Amazing quality both in looks and sound.

Cons: None

Crutchfield customer from Stafford, VA on 11/1/2018

Crutchfield Customer Review (What's this?)

This is the second pair of Heresy's in my life. These are just like I remember from the first pair in 1983. Musical notes unheard are now clear and precise once again. The limitation of these speakers are the availability of quality recorded, uncompressed music available, I now miss my LP collection that went with those old speakers.



I'm now a Heretic!

Colin from Gunnison, CO on 10/2/2018

Crutchfield Customer Review (What's this?)

The Heresy III has a rich and full sound that holds the low ends. I wanted to round out my system with speakers that would compliment a pair of RP280fs and RP26fs with an SW-450 sub. I'm driving the system with a mid-range Onkyo at 110w per channel that provides plenty of power. Admittedly, these speakers are "higher end" compared to my other components, but the sound is incredible and holds at volumes that will give you goosebumps. Contrary to many critiques I've read, neither the towers nor the Heresys sound "tinny." Quality 14 gauge wiring and a decent amp helps any speaker. The handcrafted work is apparent, beautiful finish and materials. Pricey... yes, but if you are are someone that can distinguish nuances in quality of sound and are looking for an investment in your listening experience, these are well worth it! As a note, I purchased these on sale and when it was determined that there was only one speaker in the warehouse, Crutchfield when out of their way to fulfill the order. As usual, great service!

Pros: Rich/full sound

Cons: None so far...

Steven from Coos Bay, OR on 9/10/2018

Crutchfield Customer Review (What's this?)

Wow! These speakers sound great! Nice to have a wired speaker, they are so much richer in tone and volume capacity then anything blue tooth can deliver. Too bad they use a cheap veneer for the exterior, one of my speakers arrived damaged a nice nick in an obvious place. I contacted the CS department and they gave me a partial refund. I still have a messed up speaker cabinet, it hasn't affected the sound at all. I have this paired with an H/K 3700 and Sony HAP-Z1ES. New tech and old school Klipsch... perfect for cranking and rocking out. Everything from Johnny Cash to Porcupine Tree, John Coltrane and many many more in my eclectic collection. I'll figure out a repair to my speaker and only hope none of you get damaged goods delivered to you... strange thing was the box did not have any damage at all, but the speaker clearly did...



Full Sound Clarity!!!

Rambo from Torrance , CA on 6/27/2018

Stunning Speaker, I can not believe what's coming out on these speakers, perfect and very detailed, clear sounds, I'm using McIntosh C20 pre amp w/ tube amp McIntosh Mc 225, it was perfect combination, warm sounding likewise the style and quality, I can not ask for more! Great job Klipsch company! Thanks Crutchfield! More power to your company too!

Pros: Clear and Detailed Sound

Cons: None


Daniel from Los Angeles, CA on 6/23/2018

Absolutely stunning performance! Will compete with speakers costing several times their price. They produce a very open sound quality and play even better with a nice tube amplifier. The base is tight, not boomy. They can produce a very warm sound quality with the right amplifier.

Pros: Build quality and sound quality is superb.

Cons: None I can think of

Live Sound, Imaging, Efficiency, Life Time Build Quality

Jeff from Brockport, NY on 6/21/2018

Crutchfield Customer Review (What's this?)

Purchased over two years ago, awesome "live" sound. At first, had them placed on the floor and loved them fresh out of the box, driving them with a 100 watt/per channel amp. Few months later, started playing with the set up, put each one on Bose 302 speaker stands, added a Klipsch 300 watt sub to each channel. For approximately $800 more, I had created a system which is unbelievable. It creates a "first row" live performance experience. I just purchased the Def Tech Mythos ST-L towers as an upgrade to my setup. I really thought I would be in for another treat, especially with built in 1200 watt subs in each tower. Gave the speakers 5 days of almost non stop listening.... My intention is not to down the Def Techs but I will tell you that they have been sent back as they just do not capture the sense of a "live performance" as do the Klipsch! My next speaker purchase will most definitely be within the Klipsch Heritage Line. I am very thankful to Crutchfield and their policy which allows customers to correct mistakes.

Pros: Read the title!

Cons: none

Its Heresy !!

joe from Albion, NY on 6/15/2018

Crutchfield Customer Review (What's this?)

After 4 months with the Heresy's, I must say they are a great speaker. They sound great when being played soft or load. The Heresy can play Vivaldi to Zeppelin with no problems. They have more bass extension the there rating would suggest. Also there is NO HONKING or stress coming from the horns. A vary smooth and musical sound. I moved up from the RB - 8 ll witch in themselves are a fine speaker. I am powering them with 845 triode mono blocks at 25 watts each. Also using a tube preamp. I highly recommend the Heresy's.

Pros: Great musical speake. Great looking. Compact.

Cons: none

Super awesome speakers. Super tight sounding, they can take a beating and keep on ticking! The sound that comes out of these is everything I read. A buddy has a set from 1985 and he described them to a tee. Great purchase I would buy again

Pros: Great dynamic sound highs mids lows super tight

Cons: Bass not super low, but tight

Crutchfield customer from Anchorage, AK on 5/14/2018

Crutchfield Customer Review (What's this?)

Incredible sound. Beautiful look. I was searching for a long while before I found these, and I absolutely love them. If you want good clean sound in a beautiful cabinet, look no further. The Heresy III are fantastic.



Great sound-cheap binding/connection points

matt from Pittsburgh, PA on 4/26/2018

I've had the speakers for over a year now and am generally happy with them. I have a tube amplifier and because of their efficiency they are a great match, however the binding posts are very irritating due to the fact that the screw down clamps are plastic. I have expensive biwire speaker wire and to get them to tightly secure the wire is a struggle. Don't think about moving the speakers even slightly or they will disconnect. I don't understand at all why they don't have banana plug options for a speaker that costs this much.

Pros: sound-style

Cons: for the money I expected more

Best speakers ever

Crutchfield Customer Review (What's this?)

The speakers are so awesome, the clarity, it's like u are sitting there in front of the musicians. These speakers are the real deal. The best money I have spent on audio equipment. The price makes you look twice but so well worth the investment. I love these speakers.

Pros: Awesome Beautiful and full sound Clarity

Cons: Price, then you listen to them and price is no longer such a con

Great Sound and Look

Brian from Boston, MA on 10/5/2017

Crutchfield Customer Review (What's this?)

We love these new Klipsch speakers. We've been living with my great but small Bowers and Wilkins bookshelf speakers bought in 1984. The step up to the Klipsh has been well worth the wait. The sound is as beautiful as the aesthetic (the retro look is cool).




Stephen from Bonaire, GA on 7/24/2017

Decided to upgrade from a very old but very good sounding pair of JBL l100's. All I can say is WOW!. A different sound from what I was used to. Very clear and defined. VERY PLEASED.



A satisfied customer!

Gary from Tucson, AZ on 7/19/2017

Crutchfield Customer Review (What's this?)

I'm not an audiophile but the Klipsch Heresy IIIs (California black walnut) look and sound awesome! I'm powering them with the NAD C 368. I'm one happy camper!

Pros: Great clarity and soundstage. Takes everything my NAD 368 can throw at it.

Cons: Maybe, just maybe could be improved with a subwoofer but then, I won't know until I try it.

Enjoy the sound

Audiophile speakers for music lovers, and vice versa

Kevin from Takoma Park, MD on 5/9/2017

Crutchfield Customer Review (What's this?)

Super great sounding speakers. The reviews I read are accurate, though I was afraid I would not like the Heresys as much because of my audiophile heritage, having owned just as expensive electrostatic and electrodynamic speakers and had gotten used to superb imaging and large presentation of the soundstage. The Heresys do these things just as well, and do one more thing, which I think has to do with their large cabinets: they express a lot of weight and, well, punch, to the music. Voices and instruments have a certain fullness to them that I've not heard from any other speaker, and this fullness is matched by a great top to bottom evenness in their full sonic spectrum. Best audiophile speakers I've heard anywhere near the price. A great match for flea-watt single ended triode (SET) amps; pair very well with my Decware super zen triode's 2 watts - plenty loud. There is something about SETs and very efficient speakers that sounds just right; Hi-Fi heaven with a high-end 'table like my SOTA Sapphire. And don't believe the spec sheet, which says Heresys go down only to 58 Hz - plenty of bass and impact. I didn't even bother to hook up my sub, thus one less piece of audio gear to own, and put somewhere. Finally, the Heresys are beautiful pieces of furniture that have just the right dimensions and stature, sitting on the floor with their risers, and, placed along a wall, blend in to one's listening room (which I still call a living room, where a stereo belongs) perfectly.

Pros: Beautiful to look at, incredible full and even sound, plenty of bass, very well balanced - mids and highs are just right, great imaging, easy placement for getting the soundstage right, super for low-power tube amps, made in USA.

Cons: Nothing I can think of, compared to other speakers I've heard at a similar price.

Natural sound

Guy from Santa Monica CA on 5/3/2017

Crutchfield Customer Review (What's this?)

This is a terrific speaker for all genres of music, from solo cello to jazz, symphonic and also rock n' roll. It sounds great with solid state amps, and even better with tubes. It imparts the feeling of live music even at low volumes. I've owned far more expensive speakers, but prefer the effortless realism of the Heresy.

Pros: Big, effortless, natural sound.

Cons: I didn't buy them sooner!

What are you waiting for ?

Mike from Oakfield, NY on 4/19/2017

For would be buyers: I have been "ROCKING OUT" a pair of Klipsch Heresy's that i bought in Germany, in 1982. I just love music & listen to all kinds of music, from classical to country to pop to rock to rap to EDM & bounce music. This has been, BY FAR, the best long term investment i think i have ever made. They have brought me joy everyday for over 35 years & am jammin out right now with those same speakers. I like my music LOUD & I like my music CLEAR. Klipsch has been delivering the goods to me every single day. Everyone who listens to my system ALWAYS writes down the name of the speakers. I also have 4 small Klipsch in my garage. They rock as well. Can't believe all that sound comes out of those little speakers---neither can my neighbors ! Heresy's are Made in America too. Don't hesitate----get you some of THAT !!!

Pros: Best long term investment ever ! They are now almost 3x what i paid but still worth every penny.

Cons: Neighbors ! LOL

Klipsch Heresy III BK

Crutchfield customer from San Antonio, TX on 3/14/2017

Crutchfield Customer Review (What's this?)

These speakers replaced some very good bookshelf speakers for me. In comparison to what I had, the Heresy IIIs sound very much like the larger speakers they are. Bass from the non-ported acoustic suspension woofer is tight and clean. Soundstage seems wider than before, and speakers are more neutral sounding than I expected from horns. Sensitivity is good, and I can drive them louder than my wife will tolerate with 80WPC. Midrange and higher frequency bass is excellent, percussions kick, and bass guitar rhythms have feeling. To me, they really shine on rock & roll, and instrumental music. Not top choice for electronic dance music or rap - they'll play that but you'll find better options for less money. Even though the Heresys have 12" woofers, they aren't designed for deep bass or boom. Might need a sub depending on your listening tastes.



You will love it!

these are the best speakers i have ever owned! The sound is just amazing. I also have th RP280f that also have excellent sound but the heresy 3 just has this unique sound you just cant stop listening to!!! I was hesitant about the bass, thought it may be to little but has good punchy bass that is just perfect. The highs and mids make it seem like you in a live performance:). No regrets here period. Also Crutchfield service can't be beat arrived on time and their website is perfect easy to navigate and find products easily. And also lots of information on products! Love Crutchfield. Thanks

Pros: Sound, built quality. Crutchfield service

Cons: None

David from Thunder Bay Ontario on 1/9/2017

Crutchfield Customer Review (What's this?)

Honestly the reason to buy these was that my JBL-L36 set bought in 1977 were tired and bleeding, after a thousand hours it was time for a change. I had looked at many kinds of speakers but always came back to the Klipsch brand. After just unpacking and rewiring the new units the sound was clear and revitalized. They came fast and loud ,plugged in easy to an old system. WOW !!!

Pros: Big sound

Cons: none

Klipsch Heresy III

Crutchfield customer from Reading, PA on 10/1/2016

Crutchfield Customer Review (What's this?)

The speakers were a birthday gift and my brother stated that while a little "tinny"'when first played, within an hour then warmed nicely and sound wonderful. Also from a design perspective, they are a classic style that fits well in most mid-century modern decors. Technically, as I read, my brother confirmed that they do not require much power to drive to sound amazing.

Pros: Sound amazing and warm up nicely. Design and style are both classics.

Cons: None.

an amazing speaker

Tim from Indianapolis, IN on 8/25/2016

Crutchfield Customer Review (What's this?)

I wanted to live with the speakers for a couple of weeks before reviewing. Their sound is unique and it took a few hours of listening to get used to it. The sound is dense and there are no gaps in the sound stage. There is, however, no sacrifice of clarity or detail. Every instrument can be identified and placed. The best way I can describe it is as a virtual wall of sound but with each instrument precisely delineated. The oft noted lack of bass in the Heresys is not an issue with me - I listen exclusively to classical music and the Heresy faithfully reproduces all the instruments of the standard orchestral ensemble. Bass violins, cellos, and bassoons are lifelike and distinct. The full and rich sound these small boxes give out is nothing short of amazing...probably the best speaker I'll ever own.

Pros: Small footprint and doesn't require high end equipment to produce great sound.

Cons: none

What's not to like

Joe from cheney, wa on 8/19/2016

Crutchfield Customer Review (What's this?)

The Heresy III is an old school 3 way speaker, that just sounds great. The highs are as good as it gets. The midrange is what makes this speaker a rock star. Listen to Black Sabbath's Iron Man, Rod Stewart's Maggie May, Badfinger's Baby Blue, and you can hear the high end crossovers and electronics that make these tick. The 12 in woofers go down to 58 hz. Low bass is between 20-80 hz so 58 hz blends in nicely. I do not like muddy bass. I like smooth bass. A good sub woofer can satisfy most bass freaks. These speakers sound good with a home theater setup or just by themselves in stereo. I like the efficiency of Klipsch speakers and the bang for the buck delivers impressive results. I am now awaiting my Klipsch RC 64 II center channel to compliment these for the home theater exp.I will review this latter.

Pros: High effiency, Impressive sound and imaging,Classic old school Klipsch

Cons: none noticed

Klipsch Heresy III

Joe from Scottsdale, AZ on 5/23/2016

Crutchfield Customer Review (What's this?)

Well, I finally ordered them and all I can say is I am glad I did...really glad. First, I was skeptical about the possible horn sound-I can tell you it is not there! Next, fit and finish-beyond expectation; made in America DOES mean something. The subwoofer issue-subjective to say the least. I am enjoying them without a 'woof' and the sonic footprint is fantastic-crisp, well detailed and with an old school hifi sound that's killer. The bass is tight and quick...I do have a good integrated (Rogue Sphinx). Sure they image a bit low, but the sheer sound pressure is addicting-they are forgiving in regards to room placement. I felt a need to compare them to a tower speaker in the same price range, so I did! I had them side by side with the Monitor Audio Silver 8....the Silver 8's CANNOT HOLD A CANDLE to the Heresy's...nuff said and they are now boxed and ready to re-ship!! If this is your price range and you have good equipment up-stream (my digital source is an Oppo Bdp 105) plus good cables, I believe these babies are hard to beat. Bye the way, they look stunning in black. At 30 hrs in, they are loosening up and its getting better. I can only imagine what a quality all-tube integrated amp would do...I will be saving up some cash...haha!! To all who helped me at Crutchfield, a heartfelt thanks. I will be doing business with you all for a long time to come. Thanks again.

Pros: sweet! Absolute incredible bang for the buck!! Use good electronics and they will reward ya!

Cons: zippo, nada

Heresy III

Christopher N. from Manchester, CT on 5/11/2016

Crutchfield Customer Review (What's this?)

I had always been fascinated with Klipsch Heresy's since I was 16 years old, having purchased my first stereo receiver, CD player and small bookshelf speakers. They were beyond my means at that time but I always found time to listen to them in the showroom of a local HiFi shop. After entering the Air Force I purchased my first set of Klipsch speakers (Tangent 300's) but still longed for the day that I could afford better gear, including Heresy's. Fast forward to 2016. Now that I have the means to, I purchased a pair of cherry Heresy's. The first evening I had them hooked up was spent listening to Pink Floyd - Dark Side Of The Moon and Electric Light Orchestra - Eldorado. Pure sonic bliss! I look forward to this weekend when I can really let loose with the volume and my music collection. Long live the Klipsch Heritage line and long live the Heresy!

Pros: Excellent mids compoared to most 2-way designs. Ample bass above 50Hz (really kicks). Smart cabinet (especially in Cherry).

Cons: Does need a subwoofer if you listen to music that goes below 50Hz, or for use in home theater.

Speakers Have Grown On me.

Derb from Chandler, AZ on 4/10/2016

Crutchfield Customer Review (What's this?)

These speakers replaced my Legend KLF-20's. Initially I had a hard time adjusting to the new sound. My KLF's had plenty of deep base but after installing these I noticed a lot of my music had been sounding muddy. Although the Heresy III's don't have the base extension the tightness of drum and tom-tom is excellent. I auditioned with Eagles "Hell Freezes Over" in DTS and all the music sounded much more musical. I plan to add a sub-woofer for movies and to fill out my sound profile for other music but these babies take up a lot less space and are much smoother than the KLF's. Worth the $$$$.

Pros: Great clarity for Piano and Jazz, Small in comparison to tower speakers requiring a small footprint. Excellent sensitivity, and hard to beat without having to upgrade my amp and pre-amp.

Cons: Low base is lacking, will need a Sub if you are replacing large ported towers.

Crutchfield Customer Review (What's this?)

I wanted to review these and answer some questions I had. I was scared to spend so much on a 1957 speaker. (yes I know they have evolved slightly).I was looking at a lot of tower speakers to build/upgrade my Stereo setup I had going in the man cave. Had some name brand big 3 ways from the mid 90's that were impressive. Also some other mid 90's 3 ways that were so so at best. There is this hype and buzz around vintage stereo equipment right now. I have an old very scarce Marantz and a 90's Yamaha. Neither are "Monster" receivers so I was worried about power output. After reading a few reviews I was pretty sure I wanted these. I just needed that push from someone to say "they are worth the $$$". I asked a Crutchfield adviser. He told me perhaps I should save my $$ and look at something cheaper. Not what I wanted to hear. But good job to them for not just trying to sell something! I ordered them up. WORTH EVERY PENNY! Just like so many other reviews... Just AMAZING. My old speakers were good and had great bass. But, these are just amazing. I have built many very very good car stereos but never spent any real money on home audio. The way the highs blend into the mids and lows. The "your own personal concert at home". It's true. So, If you are like me. Quite hesitating. I promise you won't be disappointed!! Buy these! You will love them. Yes they need a good sub for those low lows so get one to go with them and you will never listen to music on your dumb 16.1 or 83.1 dolby ;-)

Pros: Beautiful cabinets, Crystal clear.

Cons: Maybe a touch pricey.

Heresey III's for old rock and roller

Cant go wrong with these speakers. Does not take a lot of power to drive and you can really crank them up!. I am hearing things on my CD's that I have never heard come through before.

Pros: Great quality will become an heirloom of your family because they last forever.

Cons: Bit pricey but worth it for the discerning ear.

Amazing speakers ... quite an improvement over my vintage ADS810s. When placed side by side the Heresys destroy the 810s. Vastly improved soundstage and presence.

Pros: Overall sound, quality build

Cons: pricey, maybe


CLB3 from North Carolina on 11/30/2015

Crutchfield Customer Review (What's this?)

I was looking for a pair of speakers to anchor a dedicated, 2-channel audio system (no surround sound here!). For my listening space, budget, etc. these speakers fit the bill perfectly. I am driving them with an Outlaw Audio RR2150 receiver (another outstanding product!). Regardless of the input (CD, vinyl, streaming audio), they sound fantastic. Rich, pure, full sound at any volume. I could not be happier with this purchase. And, kudos to Crutchfield for their quick, professional service. The speakers were to my door 2 days after I ordered them. Some have commented that these speakers are expensive. I disagree. For what you receive they are one of the greatest bargains in the world of audio equipment. I have auditioned speakers that cost many times they price of the Heresey III's that cannot hold a candle to them.

Pros: Pure, clear sound. The hand crafted workmanship. Value

Cons: None.

you will be satisfied

jazzejephh from Michigan on 11/23/2015

I'll tell you there is nothing better, so, don't let your friends try and talk you into that other brand....

Crutchfield Customer Review (What's this?)

I purchased a pair of Klipsch cherry Heresy III speakers to replace a pair of 30 year old Klipsch La Scalas. I was worried about the low end, but after discussion with a Crutchfield rep, I made the purchase and absolutely Love the look, the rich sound and the tight low end. They are perfection to me, mini La Scalas!

Pros: Beautiful cabinetry, wonderful rich sound that only horn loaded speakers give you. Bass is more than adequate. Midrange is rich and high end crisp.

Cons: None

klipsch heresey 3

Rick from Gulf Breeze, Fl on 11/18/2015

I bought these with a Yamaha A S500 amp to replace my old 5.1 surround for the TV only. My only source is the cable box, I did use monster cable also. The sound is amazing. I have them separated by only 5 feet, but the sound stage is huge. My friends think I have a center speaker hidden. I do not. I do not miss the 5.1 system in any way. i use the pure direct mode on the amp with no EQ. The Heresey 3 speakers sounded so good, I tried some music from the cable box music channels. Wow. I underestimated how great the speakers really were. So I added a Klipsch 112 sub to add some serious pro low bass. After 7 months, i kept turning down the sub. It worked best in my room with the frequency cut off at below 100 htz, and the level at about 2.5. out of 10. These speakers are so warm, with a huge sould field. It sounds like a whole wall of sound, not just a right and left speaker. Even the most complex classical symphony orchestra is no problem. The dynamic range is great, at very low volume, or extremely high volume. Every instrument is clearly heard in its own space. And that space is huge.The Hereseys have a great mid range speaker and horn that makes a difference to my ears.

Pros: Made in the USA. Huge sound stage that is accurate. So Efficient, here is no need for a powerful amp. Solid, beautiful cabnet that will not tip over like a tower speaker. Sold in matched pairs. The bass is tight and accurate, you can add a sub later if you want the very bottom of the extreme sub frequencies. I think the speaker connectors are fine. With the beautiful, wide open sound the Heresey produce, I would not care if the connectors were on the bottom or sides.

Cons: None.

Great Speaker for Blues, Jazz and Folk/Soft Rock

Kurt from Florida on 11/9/2015

Crutchfield Customer Review (What's this?)

The Heresy III is a great speaker for Blues, Jazz and Folk/Soft Rock (i.e., Fleetwood Mac, Jim Croce, Bob Dylan, James Taylor, etc.). It really seems to excel on singer/songwriter type music. I have some 45 rpm vinyl LP copies of Fleetwood Mac and Bob Dylan and the sound will make the hairs on the back of your neck stand up. Also, the speaker does seem to be sounding better as it breaks in more (I only have about 25-30 hours on them so far). When I first got the speakers, I was a little concerned as they sounded a little tight and compressed. However, they definitely are starting to open up and come into their own. I give them four stars because when playing hard rock, some of more aggressive stuff seems to distort and just sounds very good. They also do not have the low end I was hoping to get with 12" woofers. My prior speakers were Klipsch R-26F that cost about a third of the price a piece, I can say that at three times the price a piece, the Heresy III is not three times better.

Pros: Very clean sound that shines on acoustic guitar and singer songwriter type music. The speakers also look very nice and classic.

Cons: A little pricey per speaker.

These exceed expectations!

Raisin Caine from Colorado on 5/22/2015

Crutchfield Customer Review (What's this?)

Possessing a challenging soundstage (relatv.small space and narrow), I wanted closed cabinet loudspeakers versus ported towers. A few products presented themselves and often carried typically very high price tags. The Heresy III came into focus. After aprox. 50 hours of burn-in, I am very pleased to add my voice to the chorus of impressed audiophiles over these excellent speakers. I am convinced these are the best value in audiophile-grade speakers. They are agile, but not too bright. The bass is balanced and powerful at all pressure and volume levels. The sensitivity touted by others does afford maximum fidelity using entry-level equipment. All types of music from large orchestrations to subtle acoustic performances sound fantastic. There is imagery I have not experienced from my analog and digital sources before. Because I had researched extensively seeking the most impact for the dollar, I was able to set my expectations high upon arriving at this speaker. I can assure you the actual experience exceeds these expectations. I can also comment that Crutchfield has delivered! You will note the speakers are available from other merchants and from Klipsch directly all at the same price, and it was Crutchfield's product backing and satisfaction guarantee that tipped my decision. Crutchfield has not disappointed and I look forward to the next opportunity to purchase from Crutchfield. Free yourself from MP3 files! Here ALL of the music. These speakers will help.

Pros: Agile and sensitive, enclosures allow for more placement options in room, well-balanced, capable of clean loudness, American-made, great service from Crutchfield

Cons: Wasn't able to audition them prior to purchase

Heresy 3 Speaker system.

DLL from Massachusetts on 5/13/2015

Crutchfield Customer Review (What's this?)

Don't ever spend a lot of money for a pair of loudspeakers today unless you are absolutely sure they are worth every penny. There are many great speakers for much less money. Klipsch Heresy are Classic Speakers made as they have always been made. They are a time honored tradition as a speaker. They are clearly an excellent product. I have always wanted a pair of these for years. They are a perfect for the home speaker. They are very detailed and combine Klipsch horn loaded design with a closed box acoustic suspension type design. Paired with a Yamaha R N500 2 channel receiver they sound great. They are an audiophile two channel system,set of speakers. For home theater speakers,spend much less,as these are too expensive. The sound stage of two Heresy speakers makes surround sound unnecessary. For get the sub woofer with these speakers,you don't need it. Listening to two of these is very detailed without sound effects of multi channel receivers.

Pros: Clearly one of the best speakers ever made. A Classic! A superb piece of work. Once you hear these babies in action you have that sound of them imprinted on your mind. Actually considering the detailed sound of these speakers they are a bargain. In the average living room they sound as good as the Klipschorn in as larger room.

Cons: Expensive. But they do not make speakers like this one anymore. The sad day will one day come when the Klipsch heritage line is a thing of the past.

Fantastic Speaker for Classical, Pop, and Jazz

Michael from Arizona on 12/18/2014

Crutchfield Customer Review (What's this?)

Just purchased these from Crutchfield in earlier this month, had to special order as they had run out. Cruchfield was very helpful and made the process easy, I hadn't had the chance to connect them till yesterday.. On the box they say that they are made and assembled in USA. They are solidly built and seem a little bit heavy between 45 and 50 pounds I am guessing. I used banana plugs as there is a part of the binding post they can connect to after losening the binding post caps I did not test out bare wire or spades with the binding post, If you are not sure Cructhfield or Klipsch should be able to help. Numerous reviews including one from CNET emphasized how accurately heresy captures the human voice and musical experience. I had to see for myself whether this was actually true, surprisingly it is!! I started with Classical so that meant performers like Callas and Pavarotti wow I actually stood up after hearing Pavoratti for Nesum Dorma it was so real. Then I moved on to pop/rock performers like Elvis, Roy Orbison, amazing you can hear how their voices build. Then I moved on to pop groups like the Mama's and the Papa's and the Beach Boys you can hear each voice much more clearly amazing. Same with Jazz Ellington Live at Newport, or Elliot Garner you have a much greater connection with the concert quite something. That being said best purchase I have made this year I feel the music not just hearing it, hope it is helpful, you will enjoy it like I did!

Pros: *Reproduction of sound is first rate, sound fills room in way makes each recording that much more memorable *Solid Construction, Screen is solidly made

Cons: *Heavy 45 to 50 pounds *Best off using banana clip connections, binding post dials at back not easiest to use, design while solid could be easier to use

Klipsch Heresy

HubieM from Diamondhead, MS. on 3/14/2014

I purchased these speakers back in 1985. I wanted a set of front speakers to go w/my Klipsch La Scala's. Which I purchased in 1975. Both pair are still working great. I've added a THX Home Audio Receiver, Midrange Horn Speaker and the Sub-Woofer...Crutchfield is great when I call them w/issues. I have yet to purchase a Klipsch product that I was not satisfied with.

Pros: These are directional speakers. Which is how the sound hits you at concerts....from the stage right in front of you. These speakers reproduce that concert effect w/clarity to every note and vocals. You will be surprised to hear sounds from these speakers in music that you thought you knew every note. They are so efficient. Which will allow you to spend less money on a smaller Amp receiver.

Cons: Neighbors. Hard to resist not cranking them up!

happy happy happy

Whyskas from Rainier, WA on 12/17/2013

I have had these speakers since July of 2013. I have 3 setup for my fronts on my Home theater setup, 2 more to come when I get the money again. These things are awesome! I have had a set of Klipsch Promedia 4.1, 4.2 and 5.1 setups for my computer system and have found no others that can even touch them. This led me to by these Heresy III's. I was actually going to buy a set of RF-82-II's but then I got to readin reviews on the Klipsch web site and decided that I should go with the Heresy's instead of the RF's. I'm glad I made the decision to do so. I don't even have the rear speakers and it sounds like I'm at the theater already! Of course I have the SW-15 for a sub, though it really isn't needed for music listening, more for Movie time. Talk about a sweet sound! I recommend these to anyone, they are awesome!

Pros: Clean clear sound

Cons: None.


KYLE from NEVADA on 10/1/2013

Crutchfield Customer Review (What's this?)

I read reviews that stated they were lacking in bass response. I have no issues with the sound in any range. Granted I'm running a 12 inch Klipsch sub that pairs well with the speakers. I turned the sub off and still loved the range of the speakers. From Sarah Brightman to Slayer, these are great!

Pros: Great sound, classic looks.

Cons: none

Product Research


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 ]
Klipsch and unbeatable combination [ Timothy P. Slon  Aug 04, 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 ]

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 ]

8 questions already asked

These items have minor cosmetic damage that could be visible but then might not be. We have no way to check if it has a blemish and if so, where it is located. In some cases the manufacturer's accessories have been replaced with generic equivalents so they will be able to work like new speakers (all the way down to still having adhesive rubber feet) and there is not even a blemish on the speaker. No matter which it is, you still have the manufacturer's warranty on them. My Bio: [ Paul  Feb 21, 2019 ]  Staff
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
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. [ David  Nov 02, 2017 ]
