As far as the cost/Sabine, that works to a point. However, doing the 8" thick will yield better control at the bottom end. So, you'll get more 'targeted bottom end' Sabines with the thicker material vs 2x the surface area. All depends on what part of the room you're addressing, what else is in there, what it's to be used for, etc.

Sorry for asking, but why would be 175 kg/m3 overkill? Because of high cost of such materials?
Absorbtion above 100-130Hz is relative simple to handle, below 70Hz is very difficult.
