While selecting materials to construct DIY absorbing panels, I found that Knauf (insulation) listed specs on the amount and main frequency of absorption for their products. I selected the right product to tame about 90-100 hz and covered with a gauzy, decorative fabric. . So yes, insulation can absorb lows if it's what the sound reflects from. Poly vs paper vs no batting made differences in the specs. Might look that up, compare to what you're using. The vapor barrier makes it tougher to predict though..
Room Too Dead
Hello All,
I am looking for advice and ideas on how to condition my Home Theater room. I built the theater in my unfinished basement. The foundation walls are covered in insulation and vapor barrier. Instead of construction walls to cover them, I chose a "pipe and drape" to cover the walls. I believe that the room is too dead. It seems to affect overall soundstage in the midrange range. Does anybody have experience with this problem and ideas to add a little "excitement" to the room? Thank you all.
