There is Glass wool (seems to be similar to north american "pink fluffy stuff" which goes from 10 kg/m3 to 32 kg/m3 Thickness: 25 mm to 200 mm.

Ready to build my 24" bass trap wall, and think I'm going to go with the Knauf ECOSE batts. I'm curious which R- value will give the best results.

In a previous post, Avare suggested "as light as possible" for a 30" trap. I'm assuming the same goes for my wall, or should it be a little denser since it's technically a little less thick?

The porous absorber calculator suggests that a GFR number below 3 kPa.s/m^2 or so starts to yield diminishing returns in terms of response. Just want to make sure I'm making the best choice. Thanks!

R value is irrelevant. Over 9" you want to use the lightest, least dense insulation availabe. Typical batts, like the ones i believe you are refering to, have a gfr around 5,000.
