If I could find a couple of guys that I could count on to do really good assembly work, I'd hire them.

Yes, just make sure you get ones made before 1984 as the drivers are way better, with the exception of the woofers. The very old ones that used Electrovoice woofers were great. I've done many of these first thang you do is to front mount the horns, this is huge and if it's the only thing you do you will have improved them greatly. The bad news is the E V sp 12's can't be front mounted ( very early Heresey's). Second thing is the crossovers, do like they have done here and make new modern ones. Do not use the iron core auto former or anything like it. Change the crossover frequencies to what is more reasonable for the size of the midrange horn be it the K 700 K 600 and the K 400. The 400 can go fairly low but the others, not so much. The La Scalia's bass horn can't go above 400hz, so you half to run them that low but improved quality components will net good results. And lastly brace the cabinets and quality insulation as mentioned here. The original K horns had true 500hz sized horns but need to be made much more rigid and damped on the outside. Some of the early K horns will except Altec 511E horns with the 1.4" entry. I like the Altec 290E driver in this setup as the phenolic diaphragm is better damped, but with 288's you certainly can't go wrong. Remember that you have a tweeter and won't be using the highs afforded by the 288's. Oh and horns love tube amps😁. My two cents worth having done many of these in decades past.

Can I get one of your 600 rp kits here in the uk?

@@lifewithherbthedog6509 Yes you can.

I hear ya!

Please elaborate. Do they need time aligning because the voice coils are at unequal distances from the front baffle? Does the processor allow correction of the peaks noted by Danny? Does the processor allow corrections to maintain proper phase relationships? Thanks.

Bought them because I needed something that could go up against the wall in my living room, look good with my decor and not sound terrible. The Forte IIIs are the only speakers that fit that criteria. And yes, I've heard all the other Heritage speakers from Klipsch. Hell I even owned the Heresy III before moving up to Forte III.

The difference between the Klipsch stuff they are upgrading and better speakers are mainly in the cabinet and crossover designs. They are correcting those issues and for less money than it would cost for outright better speakers.

Yes sir I got a used pair and I could withstand the upgrade; But never at the price point they command $$$$.00 you can literally build a better speaker for 2,000 DIY.

I have some budget Klipsch Synergy towers and their high-end sucks. Will replace the tweeters.

@@nikolasbbq nothing like a little fine-tuning.

Tyson did add strips of No Rez to the back side of the horns, and driver frames.

@@dannyrichie9743 Thanks for the feedback.

The improvement in sound quality has nothing to do with resistance. And the improvement is often not subtle.

We are already taking orders.

You'll never buy a Klipsch. Even the Klipschorn doesn't go to 20 Hz. The bass it does produce is as clean and powerful as you'll ever hear from a speaker because of the folded horn's physics. To get the extension, they'd have to sacrifice efficiency.

Yeah, no more videos in that chair.

I thought he had to pee.

the speakers were designed to be aggressive ?

@@joeygonzo Yes, like a sports car. Like the klipschorn, the forte's were designed to be efficient because back in the day of tubes, efficiency was almost a requirement. They were designed to be aggressive because the amplifiers were the exact opposite.

They still have the same basic sound after the mod as before it. The strengths of the the Forte III were enhanced, not diminished. The reason people think Klipsh speakers sound aggressive is that they are not used to hearing a highly directional speaker that is super high efficiency. So the 'jump factor' inherent to this design makes is seem like they are aggressive. But they aren't, they are just super fast. The mods done here actually enhance that strength even more, by damping the cabinet so that loud peaks are less muddy and the spectral decay is even cleaner. It's not a different tuning. In a way it's more like a 'super-Klispch" than anything.

I got to hear the Cornwall IV at the most recent RMAF and was hoping to maybe upgrade to them since they used the same MUMPS technology in the midrange that I liked so much in the Forte III. Alas, I just didn't like the sound of the Cornwall, or I would have sold the Forte III and bought the Cornwall IV.

I have a sub with my Fortes maybe this upgrade can help

Sound separation? I am really not sure where you are coming form there.

@@dannyrichie9743 It's when you can pinpoint the source of different sounds coming from a speaker. If you're sitting at listening distance from a speaker and you can make out that the bass is coming from a completely different source than the midrange or trebble. I built a towerspeaker once, using an 8" Peerless woofer, 5,1/4 midrange and titaniumdome tweeter. They were all placed with 5mm distance from eachother about 1meter up. The mid and tweeter had seperate enclosures and the rest of the speakercabinet was filled with fine sand. When playing that speaker, it was impossible to hear where any specific sound were coming from, even when placing my head right next to the speaker... pretty much perfect. When i play the floorspeakers i have bought, which are 2x6" bass, 5.1/4 mid, softdome+ribbontweeter - i can ofc clearly hear where different sounds are coming from... the bass, mid and trebble is clearly seperated. Sorry for the lack of correct wording. I believe you call it Acoustic Center spacing.

Ideally, you hear nothing coming from the speaker. You want to create a three dimensional sound field that is layered in depth and exceeds the boundaries of the speakers.

I don't know how different the model 2 is. I have not seen them.

@@dannyrichie9743 yeah thanks for the response just wishful thinking. If shipping wasn't an issue I'd definitely send them over so you can work your magic. There are a lot of post out there from people that have done tweaks to the forte II but it's kind of the wild west and there is no data or measurements to show what really helps. In the meantime I'll be tuning in.

That chair does need some work.

gary lawrence ... it’s about compromises. 😬

You’re right

LOL I'm guessing Tannoys at this point

Even most of our own products that we offer (DIY kits) have upgrade options.

@@dannyrichie9743 And soon, the upgrade options will have upgrade options!

So, do you believe this channel 100%? They DO sound great.

Charles Katz ... yeah the LS50! Smoothen our the top end.

It is a material designed to control the resonances of MDF: gr-research.com/norez24x27sheet.aspx

take a look at: community.klipsch.com/index.php?/topic/150280-super-heresy-1-baby-cornwalls-mod/page/1/ its a long read, but a good upgrade!

I don't know. I have not seen the model 2.

I'd love to see Danny show upgrades for the RF7 III. I have a pair of them and would love to squeeze more out of them.

Do it I’d like to upgrade mine as well

With subwoofer added, I beleive.

David Kasman✌ that is the only way. I'm eventually going to order this upgrade kit would love to hear the difference.

@@jorgesalado600 I expect the difference will be very obvious. The crossover impovements alone should be day and night. I believe I can hear the stock inductors saturate on my Cornwalls (the Forte crossover they removed looks very similar to the one in my Cornwalls). As they sound good up to a certain volume level but then fall apart.

@@dksculpture just like Danny said the change a severe at a 100 decibels so thoroughly enjoy this video very eye-opening and ear catching😁

So you want a Tech Talk that's focused on .... market research? That's, uhm, odd.

@@tysonn4736 Tech talk? Oh, where was that? I wasn't referring to the occasional reference to measurements. I was referring to the topic of speakers and sound, the bulk of the video, with multiple subjective opinions expressed in these postings. Yes, that is the nature of marketing and sales. The research I suggested was regarding a broader, disinterested slice of human perception of whatever sound reproduction is being compared and promoted here, and in light of that, its relative value. The audiophile world is about as objective as the fragrance industry. No amount of specs or charting will tell you whether a speaker is "good" or "better" for most people's listening purposes, nor by how much. Online listeners will never be the same as listeners in a room with direct-comparison ability.

@@ReflectedMiles So you are bothered by subjective opinions by one person about the sound of a speaker, so your solution is to have subjective opinions by more people? Again, odd. Also, I'm not selling anything - these were my speakers that I wanted upgrade to make them sound better. So that's what we did - improved their basic (and measured) performance and used better quality parts. And guess what, they sounded better! Shocking, I know. As for value, if you don't already own a Forte III then I wouldn't go out and buy one just to do an upgrade. However, if you do have one, it might be worth it as you take a big hit selling speakers used and there's no guarantee the next pair of speakers will be engineered any better.

Tyson Neidig I am not bothered by subjective opinions as long as it is understood that they are subjective and that the viewer has no way of evaluating them, let alone pricing their worth. It makes a great difference, even statistically speaking, for the subjective data from 20 or 50 persons to be utilized instead of one or two, assuming the basis of obtaining those is as objective and neutral as possible. So no kit was offered for sale as part of this video? Just because it wasn’t offered by you personally doesn’t mean it isn’t a sales video as well. My question was about improving the YT-viewer usefulness of the work and evaluations presented, as well as being able to evaluate their cost.

Sorry man, your suggestion for 20 to 50 listeners to validate subjective opinion is quite dumb. But if you really want it to happen, I suggest doing it yourself. Be the change you want to see!

Those Forte IIIs in this video are mine. I have them in my 2nd system upstairs. I'm a single guy and I have a 1950's split ranch style home all to myself. So I have unlimited freedom to place them in the room however I want. I also have tuned the room through very large acoustic panels (which I built myself). You are right, room tuning and speaker position is important. If people have not worked on that, they should. I did the upgrade to the Forte IIIs after I tuned my room. Because I thought they could sound better than they did stock. And I was right. After the upgrades they sound much better than stock.

Welcome to the 21st century. So annoying what people expect to get paid these days.

They are my speakers and while they are certainly better, they are definitely not "the best". But they are good enough for my 2nd system which is in my upstairs living room listening area. Now, if you go downstairs to my dedicated room in garden level basement, the Super 7 planar magnetic speakers down there are much closer to "the best".

Fuck off
