Do you want to be a guinea pig, and spend money, time and effort on an unknown, or stick with proven materials?
Hehe. Of course not. Hence the reason I'm asking here. I emailed the company before I posted here. I thought maybe someone had experience with it but.... turns out no. I know a product called Tontine Acoustisorb here is australia is awesome and I think that is polyester but it is quite expensive.

Acoustisorb 3(50mm) Sound absorbtion coefficients:
125 250 500 1000 2000 NRC
0.40 0.70 0.91 0.95 0.94 0.9

The 90mm of the quietstuf NRC is .9 as well however I know that means sfa for low frequencies.

If I'm chunking doesn't the low frequency SAC increase dramatically anyway?
