AJ!!!

Where the heck have you been?

Kill me already.  Hmm. I'll bet I can learn a thing or two by checking your website, huh? 

Still here. "Best" is rather subjective. Best for you? I'd think you were eminently more qualified than I, regarding such.
Good luck of course, whether that be cones, domes, stats, horns, etc..

cheers,

AJ

The GR Research Studio Monitor kit is one of the best speakers I’ve ever heard and would be a good fit here,  but it needs a sub or 2.

And you’re referring to the NX studio monitor?

Yep, here's my review of it after I got to spend a couple days at GR Research listening to all their top end models:

Best mid is the one that sounds closest in character to the woofer and tweeter you're using. 

It also depends on goals. If clean symphonic reproduction is the goal you need more ways, hard cones and steep slopes. If simple music and lower cost is the goal, maybe a higher efficiency paper-cone wideband midrange with the woofer and tweeter only augmenting at frequency extremes is best.
