Ozfly: Acoustic tiles absorb sound at a very un-even rate. What i mean by that is that treble and upper mids are damped whereas mids and bass are left alone. This can skew the tonal balance, making it harder to achieve a natural and even tonal balance. This is not just a problem with acoustic tiles, but a lot of what passes for as "acoustic treatments". Yes, i am talking about the mass majority of brand name stuff from some very "respected" acoustic based manufacturers.
Suspended ceilings can do the same thing as the tiles, but also contribute to rattles, resonances and random oscillaton. They are a true nightmare to say the least.
Combining the two can leave you with nothing less than a mega-dollar system in a room that royally sucks. I'm sure that Rives can fill you in on this better than i can, so for your personal edification regarding room acoustics and musical enjoyment, heeeeeeeeere's Rives Audio : ) Sean
