A lot will depend on your listening position. If you sit reasonably close to the speakers, your choices are plentiful. If you're twenty feet back, that's a different kettle of fish and you'll probably want something a little bottom heavy. If you're moving around and the listening position is unpredictable, then wide dispersion might be beneficial. Therefore, you might want to think twice about narrow dispersion, horn loaded designs like (I believe) the Hornings. Further, if you really want to energize that entire space, you'll need to consider the speaker's max SPL capability.
In your shoes, I might think hard about the big MBLs, if you can swing a pair and the required amplification.
