My Setup - Room Treatment Suggestions?

Try a shallow cloth wave system on the ceiling area. Armstrong makes a unit that should give you an idea of what it is all about. But think DIY. Make sure what you do is fully adjustable in both the spacing of the 'waves' and the drop of the waves. Put a track on each side of the ceiling and move the 'drape' around. That way you can tweak until you are satisfied.

Go to GIK Acoustics website. Very informative site with sample layouts. The owner is easily accessible by phone... very helpful, low pressure company. The $700 investment I made with GIK panels was the best audio money I have spent. I was about to give up on my Dyn. C4's, but have since treated my room and love the sound I'm hearing.

Well, I am not gonna get something bulky or permanent (i might be moving).

And I'm really considering moving my system in the basement (down side is ceiling would rattle).

On the other hand, with system in my room, I cannot turn it up too loud... entire house is hardwood floor, it just echos and travel through out the house. And neighbors could hear it...

So it's either deaden the hell out of current room. And get some sort of defuser type. Or move into basement and make the drop ceiling stop rattling...
