Daisiu - With all due respect, and I do with you the best of luck, you can consider whatever you'd like. However, I've had smallish standmounts that were too large a speaker for a 14 ft room dimension.
Of course dynamics are a consideration, but any wilson speaker, except possibly the Duettes, is far and away too big a speaker for a 12.5' room dimension. If you are looking for somewhat even bass, you will need to spend thousands in room treatments to deal with the bass problems that you will get.
Clearly other people have had other experiences, but I've tried several times to put largish speakers in rooms that are too small, and it never, ever works out.
