NEARLY ALL FOAM, is all pretty much useless at low frequencies, and not much better in the low mids and high mids. So it matters not how the various foams test out side by side, as they are all equally useless across the most important areas of the frequency spectrum.

HOWEVER, Foam, even the cheapest foam makes A FANTASTIC FIBER BARRIER
, for rigid fiberglass board and or mineral wool, which is what you need for acceptable broadband absorption,.... and as a barrier, it has that "Studio Eye Candy" appeal to boot.

Here is the FREE RECIPE folks for a typical 48"x24" WEENIE TRAP:

3 sheets of 48"x24"x1" thick Rigid Fiberglass (i.e. OC 703 or Rolux 60)
COST = $25 ave.
3 sheets of 48" x 24" x 1" the foam of your choice ( I like the wedge style)
COST = $18
4 little 1" x 1" wood blocks
COST = seriously?
4 screws
COST = .25 cents,.. if that.
1 tube adhesive
COST = Free from most foam houses with order
1 pair of scissors
COST = You already own them

Sandwich the rigid boards together.
Face with the foam of your choice (Front and Back)
Cover all exposed edges with "foam strips" cut from sheet #3
Attach 1" wood spacers
Attach to wall with screws leaving 1" air gap

Total Cost is under $45.00,.... keep $150.00, plus shipping in your pocket each and every time you build a "WEENIE TRAP"

Enjoy!,
