With that kind of money in play, you should go to a show or two to sample a wide variety of types of speakers. That should include large panel speakers (planar magnetics or electrostatics), Multiway systems employing widerange drivers to cover most of the music (e.g., Voxativ), single driver systems (Charney Audio, Songer Audio), omni directional speakers (e.g., MBL), truly oddball unique systems (Bayz Audio), and open baffle designs (PureAudioProject, Cinnamon Audio).
Of course, as I mentioned above, you should also consider compression horn systems. I have not heard that many good, modern, compression horn systems except for the tremendously expensive Goto stuff ($100k might get you the drivers for a mono system). Among the better modern systems are those offered by Volti at prices way below your target. But, again, custom systems are much better than what is generally available. If you insist on current, modern production drivers, the best are very expensive (e.g, G.I.P Laboratories in Japan make terrific Western Electric replicas) or ridiculously expensive (e.g., Goto, ALE or Cogent). Deja Vu Audio that I mentioned above has made systems with only modern G.I.P. drivers, but that can be more expensive than using exotic vintage drivers. Still, at your price level, a trip to Northern Virginia (suburb of DC) would be worthwhile.
