You have a very large space to fill with sound and you have a Bryston 14Bcubed so the power is not an issue.
If you look at the Bryston line, they have the Model T Signature speakers (which I have) and they are pretty amazing in performance with a huge amount of dynamic output. I am using my pair in a 30x35x18 room with a pair of Anthem M1 mono's at 2000 watts per channel and it sounds outstanding. I would seriously consider these speakers.
