Hello All,
I want add diffusion to my ceiling to help with slap back and flutter. Should I put the panels at the first reflection point or above my listening position?
Suggestions?

You will have to experiment. I've done all 4 variations with sucess. Depends on room or your taste. Not an exact science.
Armstrong, yes the ceiling tile people, makes a 'wave' product that is adaptable to home use. Check it out at their web site.
