I understand how using dampening materials (IE soundproof paneling) can help the acoustics in a smaller room (18X12). But my question is, do you try to dampen the sound in a larger room (25X25) as well? Are there acoustic benifits to this? Has anyone tried those sound proof panels? Do they do a good job? Or is there some price range they have to be before they work. Not sure this is the right forum to ask questions about an HT room's design my last post here was removed but it's a very imporant question for me as I plan an HT room. I don't know of another forum to ask this type of question in.
