Absorption panels on ceiling..what to expect?


I am planning on adding some absorption panels on my 9.5' ceilings in my small room. I am curious to hear from others what kind of improvements I may be able to expect. I already have bass traps in the front corners, panels at 1st reflection points and absorption panels on the front wall between my speakers.

Thank you.

I once tried tacking some of those soundproofing tiles to the ceiling around the first reflection points and, wouldn't ya know, they screwed up the sound. Kinda like Sonex. Made the sound all phasey like.
I would expect a decrease in sound quality. I would expect the space to be dull and over damped.
What facets of reproduction are you wanting to change or improve?

Good question.

I would think that diffusion on the ceiling should be tried. You have a small room and have done well with the absorption treatments thus far. Absorption on the ceiling may result in a negative effect on the highs.
Thanks guys. I frankly don't know what I'm trying the change. You don't know what you don't know right? So far I've been very satisfied with the room treatments I've added. I figure adding ceiling absorption is the next step in my phased approach to room treatments. Ceiling treatment were also recommended to me by Vicoustic as well as RealTraps.
