This may be Much Ado About Nothing. I don't imagine you are going to place your speakers along the 22 foot wall and in about 3 feet from each side.
I suspect you will place them about 9 feet apart and set up your listening area about 9 feet back from the speakers. Go for the resolution you are looking for along with a clean and pure presentation. I wouldn't suggest monitor speakers but a good speaker with an 8" woofer or two should be fine. To accommodate your large room augment your speakers with a good sub woofer that you can adjust both volume and response, this way you can have your cake and eat it, (or listen) too.
Big speakers can really sound muddy and bloated and not as revealing.
