is this sponge as good as acoustic sponge?
I stuffed a couple pillows behind the main speakers an heard a slite improvement attached image.
I would like to have a few acoutic panels directly behind the main LRC speakers then the first reflection points on side walls my right front main speaker is a tad close to the right wall approsmently 10" I would like sponge on this side wall to prevent reflections.
I plan a QRD type diffuser on the back wall surrounded w/ the same sponge.
I would prefer to use sponge instead of stuff like fiberglass or Roxul rockwool (don't want to be itching and breating fiberglass). plus the exposed sponge looks kindof cool.
I'm kindof leaning toward this walmart sponge because it's white (unlike 99% of actualle acoutisc sponge) it's inexpensive and it's thick.
any tips is appreciated.
