This video explains how he was able to tame forward/aggressive sound of Cornwall IV by damping the ringy platic horns with Dynamat.
Also, CW IV reportedly sounds much worse when turned up loud, presumably due to horn housing resonance and probably also due to the iron-core inductors in crossover.
So try turning up the volume at the audition and maybe try to compare with Forte III and Heresy IV for our benefit?
Follow Ups:
Jon L Try placing a piece of dynamat on either side of the tweeter butterfly tab. Cove the full tab and leave the metal terminals sticking out. This tab rings like a doorbell.

If you screw down a horn it does not ring. To get enough acoustic energy through one of these horns to cause that issue is truly frightening.

That's been a problem since the originals. It's part of their ear-gouging heritage -- but only part. :( Hard to believe they wouldn't have fixed this.
I did live with a pair (mine from 1974)for a decade, so I do feel qualified to comment on them, at least from an historical perspective.
all the best,

Mark,
How were you able to live with the Cornwalls for a decade? I am not criticizing; I am just wondering how that was possible. I can't imagine tolerating an "ear gouging" speaker for any length of time.
I have only heard Klipsch speakers on two occasions. The first was a set of LaScalas at a recent CAF. The piercing, shrieking highs were so bad I turned right around and left. The second time was a set of original Cornwalls at DejaVu Audio. Despite the careful setup and compatible tube amps, the highs were also piercing. I could appreciate the excellent bass and imaging but there was no way I could listen to them for more than a couple minutes. So my two experiences hardly qualify me as a Klipsch expert but they do give me a very good sense of what "ear gouging" highs sound like.
I'm interested in the Forte III and may end up going to LA for an audiition if the plague abates for a time......
Too much is never enough
There already exist Forte III upgrade kit if interested...
I don't have the patients to sit thru a 20+ minute video the first 10 of which is rambling nonsense.
I skipped thru the rest and STILL have no idea except 'we change parts and wires'. Never saw an IMAGE of before, let alone 'after'.....

Photos and measurements of Forte III mods are well documented at the link below. Mainly, the horns are damped, crossover upgraded, and bracing added to cabinet.This is photo of the stock crossover, with all its iron-core inductors.

I don't like the inductor layout. And SIX of 'em? This goes to a 3-way speaker, right?
No wonder Stereophile measured the real sensitivity at about 1/2 the Klipsch claim.
Bracing the cab and damping the horns? This SHOULD be done to perfection, especially considering the 2 grand EACH selling point. It's disappointing to think they need such treatment.
And Sorry, I Simply can't sit thru vids like that any more. The first 10 minutes or so? Blah,Blah, Blah followed by a meandering thru the woods. Give me a couple hours with this guy and I'd help write a tighter script and cut out the BS.
I'm a photographer in my leisure time. And you should SEE the crap that passes for 'help' vids in THAT part of the world. I find 2 types particularly irksome. The first is the guy sitting at a table or desk with a mountain of stuff. I think I'm supposed to be impressed. He picks things up and gabs about 'em. NO photos. Nothing measured, but maybe a quote from factory specs and if he is 'comparing' stuff, he'll put it side by side so you can SEE.
The other review is the guy walking around taking pictures and yakking. If they do NOT use a strap on what is probably a fairly $$$ kit? Next Vid, Please.
I'll check out the Forte III Link....

Hey pictureguy,
You may not be aware but Danny Richie has a very solid reputation for his speaker designs and upgrades. If you have the patience to wait through the pandemic for a chance to drive to LA for an audition then it seems it would be worth your time to sit through the video.
The Forte III is on my list for speaker options in my new rec room system if my modded Maggies don't work out. I thought I might have that resolved by now but the set up continues to be delayed for a variety of reasons. Anyway, while I've not heard them, I expect the only way I'd choose the Fortes would be with the mod upgrade.
Good luck.

LA as in Los Angeles? I thought GR Research was located in Texas, no?
GR Research is in TX.
I was referring to picturguy's statement about driving to LA for a dealer who sells them to audition the stock speakers. That will be an hour+ trip for him, depending on where the dealer is located.
