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?

Thanks everyone and sorry for the confusion, but my current system pics are before the recent move into my basement. Basement room is 18'x33'x10 ceilings. I'll update system pics when I get a little farther along

I'm already experimenting with panels on side walls.

I'm just curious what the acoustic difference is for spacing the ceiling panels away from the surface.
