Depends what you want to do. For trapping, use high density glass (3lb per cu.ft.). Carpet on bare floor at first reflection points. Difusion is a little more complicated.

There are some good articles on treating rooms at audioholics.com.

I gave up on my concrete bunker because I don't have the room and I would need to treat a LOT.

I used a brand equivalent to owens corning 703

Basic construction info from my HT can be found in a thread on these forums (about 1/4 the way down the page):

I can send you more detailed info upon request

Bweasner,

I'd be interested in knowing the details of the construction. Unfortunately finding Corning 703 in Markham, Canada isn't so easy.

I also went with a red colour on my walls. Are you noticing much difference in the accoustics now that you have your panels up ?

BIG difference in sound quality. I guess my room is a lot like fredk's...a concrete bunker (laughed out loud at this, never thought of my basement this way \:\) ) After I installed all the drywall in the room, the smallest sounds would echo like crazy. Even dropping a drillbit sounded thunderous.

Now, I hear no echos or muddiness at all in the theater (except for a litte bit of reverb coming from the untreated stairwell, but I don't think there is anything I can do about this). It is nice to be able to have a conversation in that room (no movie or music playing, of course) and not hear your voice echo at least two or three times.

great looking panels!
simple and inexpensive to build
do you think i can get away with shallower ones, say an inch in depth. i prefer a more subtle panel

The thickness of the panel is directly related to the lower frequencies it can trap.

Exactly! I think that the recommended thickness for the lowest frequencies (bass traps) is AT LEAST 4-6" of fiberglass. ClubNeon, do you know?
