Yes...it will not sound as good (as it could) if you have the speakers mounted in the ceiling corners. But, if asthetics are key, it'll just be a matter of determining whether or not they sound good enough located there.
If sound quality is key and free standing speakers are out of the question, you'd be better off with in-wall/on-wall LCR speakers.
Just my 2 cents.
