Thanks for your input. I thought a density of 100ish was optimal for low freq absorbtion (in rockwool) but reading through this thread it seems like most people use less dense material. What's the consensus on this?
I wanted to use the OC 705 at first, but OC aparently don't sell those or any other isolation panels in europe. I've been looking all over for suitable replacements and this was the closest match that I could find.
