Whats the best way to get good absorption on the ceiling?
I have some 4" Ultratouch, should I do some sort of cloud?
I have some left over diffusers (Auralex) that I will try on the sides.

Thanks,

Clifford

You could do a cloud, or you could just glue some of that Auralex foam up there.

I don't have any absorption data on UltraTouch.  From their website, it appears that it comes in 3.5" form, which is probably what you have.  If you can point me to a site showing acoustic absorption data and the means by which it was measured, I'll look it over.

This may be a dumb question, but could one not install say 2" foam OVER another layer of 2" foam, and thence get 4" worth of abs?

Sure, as long as the back side of the 2nd layer of foam isn't faced with something that is acoustically reflective.  (This would typically be most true in the high frequencies.)

It also seems like the rear corner would be a great place for a "super chunk" bass trap. Easy to build and very effective.

Scroll down about 1/2 way for a nice little turorial...

The article mentions that the burlap used to cover it doesn't come wide enough fit the frame, but I didn't have any trouble finding wide enough stuff at JoAnn's fabrics, FWIW.
