ceiling acoustic treatment


Just moved my system into a new room that I can experiment with acoustic treatments.

I'm using Owens Corning 703 for sound absorption.

Has anyone experimented with leaving space between the panel and ceiling? If so what was the sound difference?
How much space did you leave between panel and ceiling?
Or should I just install the panels flush?

From the photos, I would suggest first working on side wall reflections before worrying about the ceiling. I have a cathedral ceiling and did eventually put 6 2x4 panels up there of Owens 705 with Ready Bags from Ready Acoustics Co. I did angle them like louvers. They are about 18" from the crest of the ceiling. The result was less ringing, clearer trebles, less stridency in female vocals. I think in general that putting a panel straight on a wall will only limit higher frequencies, but putting one several inches from the wall or ceiling will help trap lower frequencies as well.
