Hey guys, I'm finishing off a 23x13x8 space in the basement as a dedicated room.  Just wondering if anybody has ever used the Ceilume ceiling tiles instead of a traditional drop ceiling.  If so, what do you think of them?

I'd think they would work very well acoustically speaking.  The thin vinyl should pass frequencies below 500hz or so into the fiberglass that'll be behind them, and certain shapes look as though they would function somewhat as diffusers at frequencies above that.

The other thing I'm planning is to use GP Yellowboard panels instead of traditional drywall or Greenboard panels.  It is a basement and can get moist, the yellowboard is made for moisture resistance ... but should have the added benefit of being excellent for acoustics.  Home Depot here just started carrying Yellowboard.

Diffusion requires depth, so tiles with a thin "relief" pattern will not do what you hope. The patterns would have to be at least a few inches deep to be useful at audio frequencies.

I realize that ... if they have 3 inches of relief they'd provide diffusion down to around 2250hz, which is more than a flat painted ceiling would.  I was more interested in the product itself, if anybody here had used it and what they thought if so.
