Ok, there's lots of variables to consider there, that are not mentioned - like, for instance, what electronics do you have?(sonic compliments?)... Is this a single seat, "sit in the middle" HT setup?... Are there other off-axis seats to consider, etc?
I mean you could easily pick a pair of horn speakers that don't properly cover the area you're trying to reach, in regards to your seating locations. Basically, the water-fall plot falls off like a rock with horns, when you sit off axis (roll-ed off mid/high's). So consider. Also, other designs like Dipoles can exhibit this problem.
I would recommend some horn speaker if you can set em up right, likely in a Dappolito configuration design.
Then again, what's your room setup/layout like? Do you have a low ceiling in a long room? Do you sit close? That all matters! Without knowing your room setup and acoustical considerations, I would be safe in saying to stick with some otherwise sonically excellent medium to high sensitivity designs.
Speakers that would fit into this category, and otherwise offer good sonics would be Used Paradigm Studio 450's, NHT M5's, NHT VS2's(?), maybe a larger Klipsch Reference center (ok refinement, great dynamics!), Older Dunlavy SCI's were excellent, Mirage THX (forgot models), and others.
The deal with the Klipsch's, IME, is that they always sounded better with tube gear. So, that's just me though.
But, it all depends on the level of sonic refinement you're after.
At this price range, you'll really have to try something, and likely try a few to find out what you're after.
Besides that, you've gotta be more specific...
