  Foam is expensive, that is why my DIY acoustic prohjects use fiberglas and polyester batting.

  See:
  http://www.geocities.com/jonrisch/a1.htm
  for some details on where to put treatments.

  As for te thicjkness, the biggest sigle mistake is to use treatment that is too thin. YES, double up on it, avoid a solid backing (use peg-board, or a more open frame, etc.) and space it away from the wall, if spaced several inches, this can almost double the LF absorption!

    Thanks jon, I'll double the foam. Do I put them on top of each other or maybe back to back? Does this matter?

      It is a dense wood composite usually dark brown in color(trade name "Masonite") that has holes in it like you might use in your garage to hang hand tools. Varying thicknesses from maybe 3/16' on up.
