Micah, I'd never describe my M80s (or any Axioms I've heard, including M80s in a giant cavern of a room with a marble floor and a severe lack of furniture and room treatments) as being shrill or sharp. How loud are you planning to play this stuff for your clients? If you're under 80 dB, you should be just fine. If you're going to blast them out of their seats, well, you've got more problems than just a live room! ;\)

I am the Doctor, and THIS... is my SPOON!
