You need to find an individual who can design series crossovers. Both JBL and Altec used these, because they sounded best. You will need to look for an individual near where you live because they will have to test the drivers as the design progresses. You can of course utilize a parallel crossover, but a significant improvement in all categories will only come from a full series design. If you lived near Seattle I could put you in touch with a master.

Bud, be careful with unequivocal advocating of series crossovers. JBL used some series and series/parallel ideas but only in inexpensive and non-ambition speakers. Not to mention that the fact the JBL and Altec used them means nothing. It is not to say that some of JBL small monitors sound bad but it might or might not have anything to do with series crossovers. The series crossover is a controversial project, it works with one driver and does not work with others and it never was tested with horns. The biggest problem is the “slack key” mind-set to deal with all these subject. You know well that by implanting into his mind the empty phrase “series crossovers” you will open another round of slack’s internet milking. You can implant in his mind with the very same success the phrase “cold nuclear fusion” or “non-proliferation of Asian cypress beetles”

It is wonderful how these forums work and how it's members provide the feedback and comments from their experiences and expertise.
I am 90% convinced that the DEQX will not provide the magic spatial sound that I am looking for with the Edgarhorns. If it does to some degree it will probably degrade or even kill the "horn" sound (that disappeared in Jorge's DEQX setup).
I think it's about time that I check the crossovers in my speakers... to make sure they are correct. They sound ok to me but may be confusing to someone with keen hearing. I remember I was told to disconnect a capacitor to the tweeter when I changed from the Fane to JBL 075's. Does anyone know of a stereo engineer that can propose a schematic crossover design for the drivers that is being used? Am I making any sense?

Sorry, slack but your commentaries sound not like “lesson learned”. Why are your suddenly “90% convinced that the DEQX will not provide the magic spatial sound”? Because somebody in polite manner told you about their own negative experience with this specific brand of digital EQ. What do you know about those people, their playback and cultural objectives, their reference points? Did you asked any questions that would give you indication where they are coming from? Do you understand the reasons why they do not like it? I did not ask you if you rent DEQX for a day in your local pro shop and try it yourself – it would be too much to ask I guess… So, there were two random people who said to you “no-no” and you turned away. I can give you another 23407 random people from the same internet who adore digital crossover and this playback systems are way more expensive and much “positively reviewed” then what Jorge or Adrian have. The point that I am trying to make is that so far your interest on the subject is so shallow and so artificial that the “lessons you learned” are not the lessons but the empty words that you just heard with your side hearing and for whatever reasons you decided to declare them as your “90% convictions”. I very much do not attack you personally as most of the idiots on internet would think. I just try to separate politeness to a person and a respect to the subject of the person’s interest. I do not defense or assault digital crossovers for you. But I do try to maintain the context at this site at certain level of reasons, the level that I do not see in your inquiry.
