For 90% movies, have you looked at PSA at all? They are a great home theater speaker. Their towers would be out of your stated budget, but their bookshelf speakers would be close to your budget. They aren't small bookshelves, so dont let that deter you. They use 10" woofers with a horn loaded compression driver and are very efficient (95db). The owner came from SVS actually (I want to say he was the "V" SVS but I cant remember for sure).
They'd be great for your large space. I dont listen to much music, so I can't speak to their capability on that front.
