Looking again at the EdgarHorns, the placement in the room seems nearly optimal and they are now properly time aligned.  Looking at the phase of the individual drivers and listening to each of them individually revealed that the tweeter was wired out of phase and the midrange and woofer were wired out of absolute phase.

Adrian, I am glad that you resolved you dilemma. Considering the problem you described, it was pretty much, where I expected it to be. However your explanations are kind of sound strange to me. If your tweeter were out of phase with the rest of the drivers then it would not produce the problem you portrayed. Reversing polarity of the tweeter, even with second order filter, dose has some negative consequences but the do not manifest themselves in a way your explanations were. Most likely you had one of the MF or upper bass drive out of phase and doing your experiments you accidentally put in a correct polarity. It has nothing to do with the tweeters. Also, “listening to each of driver individually” you would not be able to get the drivers’ polarity (not to mention that the “absolute phase” has nothing to do with your case at all. The co-phaseinass of the drivers might be objectively detected by a $100 worth phase tested that I literally demand to buy any person who is wiling to talk with me about horns. An alternative way would be a run a dual-channels mono in-phase sweep and to monitor the center image….

Correcting this changed the sound from very good to stunning.  The speakers now disappear in the room and the sound is the best I have ever heard from a stereo.  Really wonderful to listen to, now!

Hm… I do not know how about the “stunning”. So far they juts “disappear in the room”. That is, as I previously said not a big deal and itself doe not signify anything.

I understand why the previous owner traded these in for Cain & Cain horns; because the EdgarHorns were wired wrong!  I am amazed this could happen by a small manufacturer like Bruce Edgar who seems to take a lot of care about his products.

It has nothing to do with Bruce Edgar and his sweatshop. The problem is YOU. You should stop to extend any credit to audio audiophile and treat all of them by default as a potential cretin unless they prove you otherwise. This is what I call the Presumption of Moronity ™, something that I employ for year and something that give me a phenomenal detecting rate among the audio hoodlums. It is obvious that the previous owner of your speakers was a Moron. You told that you brought a bunch of audio hoodlums to listen your phase-screwed Edgarhorns and “everyone who hears my system says it is the best thing ever and they are totally amazed and saying it sounds so lifelike”. Dose it say anything to you about the quality of this listening intelligence and the level moronity of this audio perception? Anyhow, do not be disappointed. The very same garbage sound that you had have 99% of all audio Morons ™ out there.  BTW, if you look at the “expert” on-line comments of that fool who sold you the speakers the you will see that he know among audio constituencies as “experienced audiophile” - within many internet sites you would find piles of morons similar to him…

But comparing to the sound of live music, it is still slightly blunted and like everything is stuck in the mud, so it gets a bit confused especially with orchestral music and begins to lose the living presence, although with small ensemble work the sound is very much lifelike and I can easily forget I am listening to stereo at times.

This is very different subject and I would requite you to describe it deeper to figure out what frustrate you now. Do not forget that the Edgar’s horns have thier own intrinsic limitation rounded by the very primitive demands level of the target customers.

Next I think it will be appropriate to look at the level of the lower midrange horn and to consider rewiring the insides with good solid core wire (it is all Litz copper wire now). Does this sound reasonable as a next step?

Absolutely not! I wound live the damn wiring alone. Unless you enjoy the process of changing them…
