| Bump!
I decided to add to this post rather than start a new one. I casually mentioned in another post that I filled a 2'x4'x1.5' cardboard box with uncompressed r-19 and laid it horizontally in the floor up against my wall. I am going to guess that I am trapping bass. I have no idea about the effectiveness or to what frequencies. What a great inexpensive bass trap, though. Go to Kroger and ask for banana boxes (check thoroughly for tarantulas...lol). If you put two box bottoms together down into one top, you should get more than enough volume. Go crazy with a hole saw. Stuff with cheap fluffy fiberglass and cover with fabric. Put them at strategic places around the room. For broadband absorption, glue 1" of 703 to the outside of the box before the fabric goes on.
Viola. Your studio now smells like a produce back room!
