I'm willing to commit the time and effort do this but the big problem is deciding on the right horn/driver combo for my situation and specific goals. Please check out my thread. Any advice would be appreciated.

Man, that's quite the thread. I do enjoy the Joseph Crowe wood horns, so good on you there. I have two sets that I think may be more applicable to your apartment, as my living room is the same size and either one works well but larger would be a problem.
The first is the #1159. (
https://youtu.be/f6S2V9D9_08?feature=shared) He designed it as a typical ported 2 way but modified the design slightly for me to work with the SB Acoustics beryllium tweeter and Purifi 6.5" woofer that we installed in a sealed box. They are used with subwoofers. I prefer adjustable low bass because of Fletcher/Munson. I believe he will also make it as a small floorstanding speaker. The improvement from the controlled directivity compared to my previous speakers (more like what he demonstrates in that video) can't be overstated. The room is always the issue.
The other pair is the ES-800 one inch exit horns used with a very lightweight 12" Faital Pro mid-woofer and the same subs. A very compact compression driver based system that doesn't take up much more space than the #1159.
Either pair will play without audible distortion to levels well beyond what would be acceptable in your apartment and I think would be easier to implement in a room that size. I do the asymmetrical diagonal setup. The ES-800 are more efficient and plays better with low power amplifiers. Mine use passive crossovers but the Danville is on my radar for going active. I have a friend using one with the latest AKM dacs and it sounds great.
