acoustic ceilings

These look promising. Relatively inexpensive, seem easy to mount, and are paintable. Have never heard them in action.

Thank you, Bigby, are you using the polystyrene or
wooden versions. I am having a little trouble with
the $300 wooden price on one 2 foot square. Stupid
question: I would just use a mirror on the ceiling
to find my first reflection points and use OC 703
wrapped in grill cloth for that specific area?
Then use a pattern for the diffusers on the remaining
ceiling area similar to your photos?
Rockadanny, Also thanks,I am assuming these are polystyrene, the website seems to state they are only $50 per two foot square. Very interesting, wonder how they compare to the RPG products. Also interesting is the 23 prime QRD aspect.

Even with reflective or diffusion panels, there will still be that big space behind the ceiling. What was offered to me was that the best thing is to fill the perimeter of the ceiling with insulation and make one, big bass, trap out of the drop ceiling. I don't remember if it was Ethan of RealTraps or Brian from GIK. :-) I never did it anyway, too much work for what seems like a little change.
