Several have already mentioned the Klipsch Cornwall...I concur as well, however if you really want to pressurize a space as large as yours I can suggest stacked Klipsch Cornwall’s. I have such a set up and they are spectacular. You invert the top pair so that you have a “D’Appolito” alignment. (MTM...Midrange, Tweeter, Midrange). The only downside is some “ Comb Filtering” effects, however it’s not to bad. The stacked Cornwall’s are shockingly dynamic, and image surprisingly well, considering the Comb Filtering that takes place, especially if you can set them up so that they are well out into the room, and your seating distance is at least that of a equilateral triangle ( even a little farther back will help with imaging (the Comb Filtering effects won’t be as noticeable.)
Cheers....
