Yes, both ends of the spectrum are tough to integrate with a quality MF.
Of course, electrostats have no "push", but they seem to do all right (understatement) just supplementing way up there, in an array.
The thing is, the "big" ribbons and 'stats are made big to go low, and this is not something you desire.
So I think it gets down to using the "small" HF-only units and deciding whether you want to experiment with getting the levels where you want them. Surely there MUST be some HE HF-only ribbons by now, since most all concerts are amplified these days and "super" ribbons have become very popular for this use. OTOH, I have no idea whether the needs of concert venue sound reinforcement would translate any better into your home system than the typical small hi-fi ribbon would. I can't imagine any of the TAD pro stuff I've heard in my living room. I want to keep my teeth!
Bob Fulton's version of the RTR ESR6 was *about* 90 dB (and not more), with his cheap-o network and little transformer, and I think he actually divided the panels for "high" and "low", even in their narrow band! He was an odd duck, and cheap to a fault; but he had amazing ears! Lots of his ideas were just plain nuts, though. Needless to say, he quickly abandoned his good idea in favor of cheaper, inferior all-dynamic stuff, which is why the RTR/Peerless stuff is so sought after.
The RTRs are mostly in the hands of freaks now, as far as I know. I sold mine to Joe Cursio, "The Dynaco Doctor", a while back, and he also bought my Peerless dynamic tweeters. At the time I couldn't find the right amps for the whole set-up, and I did not want to or need to break it up; Joe had known and worked with Fulton, and he took it all.
I am not sure if the G2Si ribbons are any "better" overall, but they have fewer problems as far as higher-efficiency implementation is concerned, that's for sure, and, like I said before, the ML2s seem to "force" the match.
BTW, if you find a cheap, easy way to do this, I will follow quickly!
