I just picked up a pair of Heresy IIs. And you are right you really have to get them going to get that chest thumping drums and bass. I was a little disappointed when I first got them. The highs and mids were so perfect but the lowend punch wasn't there. A day later I hooked up my parasound to them and cranked them up pretty good and oh boy they came alive. Brilliant speakers for their size, they punch way above their weight. Sounds so live and real and LOUD. Puts my old KG4s to shame in that regard. You can keep turning these up while the kg4 will start to get distorted. Probably due to not having a midrange horn.
Bro love your honest and straight up review .Lot has to do with marketing and trying to get you to spend your hard earned cash on the latest and greatest so they have you believe .Cheers!!
I have the heresey II built in 1996 in a Mexico facility. I pulled the binding post off to check the caps on the cross over and they look new. Been using the speakers since around 1997 - pretty much as a daily driver. Still play without issue and I cannot detect any degradation in performance - although gradual degradation may be difficult to detect over time. Anyway I was torn about updating to the IV's and when I went to listen to a pair at a proper dealer listening room they sounded great obviously but not any greater than the II's I thought, so I am waiting. I looked at the Cornwall's - much more depth and bigger sound stage, but I saw a Cornwall box with the speakers out, and I was really disappointed. The interior of the box is nothing less than sloppy and slapped together like a kindergartner wood project. That gives me pause over the price. I am tempted to go to parts express for drivers and cross overs and build my own boxes as an experiment.
I bought the H3 2 weeks ago. I had an opportunity to buy the H4 but after seeing your video I decided that spending the extra $1000 wasn't worth it. Thank for the video and your honest assessment.
Great review / explanation. I'm looking to get the IV's and am pretty sold on the reviews (plus they look great), but I also always wanted to try some II's as a restoration project. Now hearing that those drivers are nearly as good (for like 1/10th the price here) I've got motivation to give them a try now
Thanks man. I have they Dynaco you have and building a decware kit similar also to what you have. Looking at both versions of the Heresy's. Really hoping I can get the Heresy II's locally that have been well kept.
But most people don't limit themselves to 2.5 watt per channel amps, LOL! Of course you're not going to notice much of a difference at those volumes. It's exactly when you turn the volume up that you hear the thinnest of the base on the Heresy I and Heresy II. I love my Heresy IIs, but I run them with two REL T7s. As much as I love them, I couldn't live with them long term in a primary system without subs.
I have noticed that you are now turning your comment section off but I would like to let you know that I really enjoy your videos and audio journey. I am in the process of re-building my system after selling my vintage K-Horns a few years ago as a result of selling my home and traveling. I kept my Fi 2a3 amplifier and am very interested in doing a Lii fast 8/ Silver8 and Lii 18 similar to what you are doing. Do you have a source for the baffle construction? Please email me with that information if at all possible. Many thanks for your work here. It is very interesting and enjoyable.
Thank you. I’d be more than happy to turn on ALL the comments of every video. TH-cam is the one that doesn’t turn them on. I have no control of it. I’ve tried to fix that to no avail. TH-cam has so strange menus that are not user friendly and take you to nothing but dead ends. I can’t understand why some of my comments are on and the others off. Wood maker is house of hardwood in Santa Monica CA. Cad drawings were given.
I just bought the Heresy 4’s from Crutchfield based on the insanely positive reviews. Hmmm. I’m not super impressed. I thought bass would be better. Don’t get me wrong, they sound pretty good. I was thinking maybe my McIntosh MA252 doesn’t have the balls to drive these. Maybe that’s not the problem? Sure they will play loud at levels over 50 on my Mc. My Maggie’s are the same way. I’ll keep listening. Thanks for the honest review. The hype has been unreal.
The age of the capacitors in the crossovers in the II's should be considered. Bob Crites can help with this or you can do it yourself and use more expensive capacitors to up grade your speakers.
Klipsch Chorus Vs Forte 1, I have just bought a pair of mint condition Forte 1 Should I have looked for the Chorus as instead ? as they say that Chorus a better speaker all around. By the way I love your channel. Thank You
I’ve never heard the chorus, but I did hear some videos comparing it to the forte one and it just sounded nicer in the forte, but that’s only a video so hard to say, but I have heard good things about the chorus. Thanks for sharing.
Forté II's are great! Chorus II's are Forté's on steroids. I have/had both. If you have room, I'd get the larger Chorus, same great sound and plenty more of it, for not much more money IMHO.
What I don’t understand is why you review these speakers with a couple watts of power, the new Hersey IV is rated 100 watts continuous and 400 watt peak that means if you want dynamic sound you need to allow the speakers to pull more power when needed. Nothing to do with volume, strictly low end notes require more power even at lower volumes. Minimum amp should be your larger tube amp, 2.5 watts is not recommended by Klipsch, try contacting Klipsch. Klipsch told me 25 watt minimum and 50-100 watts is recommended for dynamic sound. The Hersey is the least efficient out of the Heritage line, smaller speaker does not mean more efficient.
Your best Klipsch compromise is a set of Forte IIs or IIIs. Usable bass to ~38 hz. Room tune, room tune. room tune, The specs are measured in an echo free lab. Room tuning will give you even lower bass, and better sound throughout with any speaker including the Heresy, but especially the back ported IVs. I have a 7.1 sub, but I listen to Jazz all the time with no problems even without the sub. I room tuned out the standing waves, and 180 degree out of phase reflected cancellation waves. The 180 degree out of phase waves are what is used in head phones on purpose for "noise cancellation". This "reviewer " is stuck on the tube amp fad (2.4 watts is a JOKE no matter the speaker), and looks for ways to knock the folks who, like I, can hear and do appreciate the improvements. The upgrades individually are not dramatic, but when taken as a whole are very noticeable and welcome.
Dave you have no idea what you’re talking about. If anyone is bias it’s you. You think music is about blasting your ears out. You’re totally missing the boat.
@@drde4010Thanks for the STRAIGHT review! I also em just getting back into listening to Great tunes & would appreciate knowing what amps you have/run & there power .
Thanks for this...jazz really shows. The mid and treble are just so loud and that woofer is so stiff no way low bass. I love my h2 but it needs a sub. Lascala,Cornwall al, use a stiff bass driver with no low end at real listening volume. The general sound is breat but......
whats bullshit , is somebody thinking they can get bass out of a 15 inch speaker with just a few watts of power? man, hook some power up to those speakers....i bet my old adcom 555 -2 , would make them things thump
Now a year later, do you still think the H2 and the H4 sound pretty much the same? If not, which one do you prefer? And for what reasons? Can you also indicate perhaps how much % better you find one speaker compared to the other? I now own the H2 and wonder if it makes sense to upgrade to the H4. All reviews are only loved about the H4 and honestly you are the first review I come across that comes across sober and without bullshit I am very curious about your answer. Thanks in advance.
Z reviews said something very similar and it broke my heart because my dream is to get a really efficient horn speaker where I can take the sub out of the mix for dual duty Home Theater and Music. Oh well.... I hate doing a subwoffer blend, I have some Klipsch RP 160's with a 10" Klipsch sub now and it's a super good sounding set up when I get the blend right, but every input on my amp is a little different, my phono stage always needs some help, stuff coming out of the DAC needs to be dialed back, stuff coming out of straight analog line, it's usually just right, and it's frustrating to constantly fiddle with my sub levels depending on source. I can't seem to dial it in. I thought the port on this was going to get me there, but it sounds like the bass is lacking still.
I hate subwoofers and The reviewer borrowed my speaker and I can tell you that these speakers do perform on the low end. They produce down to 40hz. I got rid of my subwoofer.
IMO Mirko is correct and here’s why. I’m personally not as dissatisfied with the bass of the Heresy as most. What many reviewers rarely tell you is that some amps and preamps deliver different levels of bass than others, even at moderate levels. The other thing is the size of the room. I can’t understand why reviewers don’t explain the context in which the speakers are being played. You can get the bass you want depending on the size of the room and the way they’re placed. The bass is tight and fast! I seldom use my subs because I don’t need them all the time in fact 90% of my listening I go without the subs!
Your best Klipsch compromise is a set of Forte IIs or IIIs. Usable bass to ~38 hz. Room tune, room tune. room tune, The specs are measured in an echo fee lab setting. Room tuning will give you even lower bass, and better sound throughout.
Different cuts are going to require adjustments due to the recording mix, this is NORMA. It is just more noticeable with horns, and this is NORMAL I set my Heresys to the sound of very high quality recordings, and leave the alone. If the recording balance and quality are poor then that is the sound I get, and rightfully so.
No, what I hate are fanboys who can’t be open minded enough to evaluate something constructively. Instead, they make blanket statements without more details and just believe everything that’s newer is better. Instead, they’re consumed by marketing. Companies always strive to find cheaper ways to manufacture products. I deal with the same crap in my industry and can read between the lines. Regardless the IV’s are well broken in now so I intend to barrow them again and add corner walls to help the bass resonate more in the corners.
Place to be on the room is important for a real bass effect. You can do your video without saying bull whatever beeee... Let me ask you?. Have you ever been to a concert hall... Doubt. Bla bla bla bla bla bla bla bla
You are right. Acoustics matter and it did make a difference but for my room at the levels I play, it doesn’t impact the same way others say. Also, you’ll notice that I did some follow up videos on my channel which validate your point as well. This issue I have is that audiophiles who are far more experienced are not doing a good job putting matters into perspective or context.
36 watts is NOT much power. Sorry but 2.5 watts will NEVER do much no matter how efficient the speaker. This is why.... A watt is a watt no matter how its produced. Study the power needed to follow the "spike" of the initial "attack" of an instrument. Percussion types like the piano, bells, xylophone, drums etc can reach 120 dB. Even other instruments like the guitar, horns, and most woodwinds have an initial spike that may reach 112 dB+. An 89 dB sensitivity speaker needs 1000 - 2000 watts to produce the full waveform, but more power makes more distortion! The efficient Klipsch models can do this with 100 - 125 watts. You do not have to play music at these maximum watts, but rather the power just needs to be there. Sorry but your 2.4 watts is a joke for accurate detailed reproduction from ANY speaker. Tube amps are overrated, and any tube amp with much power will also be a good room heater as well. I did not hear of you room tuning which does make a difference. Room tune, room tune. room tune, The specs are measured in an echo free lab. Room tuning will give you even lower bass, and better sound throughout with any speaker including the Heresy, and especially the back ported IVs. I have a 7.1 sub, but I listen to Jazz all the time with no problems even without the sub. I room tuned out the standing waves, and 180 degree out of phase reflected cancellation waves. The 180 degree out of phase waves are what is used in head phones on purpose for "noise cancellation".The IVs are back ported, and MUST be room tuned differently that the IIs. My take on this is you are a "faddist" buying into the tube amp myth, and you hear what you want to hear. I also suspect that you are purposely out to "debunk" the folks who do hear the IVs improvements. I am an Electronics Engineer, and a performing musician. I can hear the improvements in the IVs, and they are not individually dramatic, but taken as a whole are very clear and most welcome. I have two sets of Heresy IIs, and one set of IVs. I also have four K-24 woofers, two up for re-coning. Early K-24 woofers have 6.7 Ohm VCs, later units are seen with 5.4 Ohm VCs. The 5.4 Ohm K-24 equipped Heresy models are 3 dB more efficient, (equal to the IVs), although the "official" II specs were not changed to reflect the difference. My IIs can fall off a cliff @ 50 Hz, the IVs are usable to 45Hz, but again room tuning gets me very clear detailed balanced bass from even the fret-less double Bass (al la Diana Krall and other such genres). But, even the mighty Klipschorns need a sub-woofer for mid 20 KHz reproduction. I play live pipe organ music such as Harvard University's Flentrop, and also modern Jazz Fusion and other styles that can go below 30 cycles. I had a set of Cornwalls but they weigh a 100 lbs, and were too much to lug around except for long term bookings. Since I needed a sub for the music I play even with the most expensive Klipsch models, the Heresys are easier to lug around, and the 7.1 sub will do surround sound when needed.

I have listened to the IV’s in my friends room and his room acoustics appear to enhance the bass of the IV’s. Your comments regarding tubes and watts sound more theoretical than a reality. Decware has a very credible reputation and you say 36 watts not enough regarding the ST70. I’d love to set you down in this room and hear for yourself. Your ears would bleed and as far as pipe organs are concerned I have several albums in my collection and it sounds absolutely incredible. So, I have no idea what you’re talking about. It amazes me you could be as knowledgeable as you claim and not know that. Tubes are not over rated either. People have been pumped up with marketing regarding amps. I think the IV’s are wonderful and they do produce amazing bass in certain rooms. Also with regard to the mighty Klipschorn’s you may want to put on a set of headphones and listen to their bass properly recorded. th-cam.com/video/U_qPJiv_qgY/w-d-xo.html

500 hours before they really sing, jerry
I really haven’t read that the bass is substantial on the IV. I’m gonna use a sub with mine anyway. Those twos are more broke in also
The age of the capacitors in the crossovers in the II's should be considered. Bob Crites can help with this or you can do it yourself and use more expensive capacitors to up grade your speakers.
Thanks I was thinking the same. What would be the symptoms regarding the sound?
Btw I reached out to Crites last year regarding this but surprisingly they were not familiar with the way the current boards were installed.

You need powered subwoofers in stereo to fill in the soundstage. I run SVS subs with the Cornwall III’s and it sounds amazing.

As good as it gets

Also with regard to the mighty Klipschorn’s you may want to put on a set of headphones and listen to their bass properly recorded. th-cam.com/video/U_qPJiv_qgY/w-d-xo.html
This is the reason I don't hang out with "audiophiles".
