In my own seat-of the pants way-...Don't even consider trying to track down goofy little blurbs like flutter and high-end comb filtering until your lows are in order. It's almost always two steps back.

Layers 3-4" thick typically tackle the high to mid range (for fiberglass that's down around a couple hundred) Patches (not -ever- full covering) of this allow partial control of ringing and flutter in that range. Standing/movable gobos and hanging overhead patches make for configurable mini environments to dial in as much or little of any room you're in -good or bad.
Here are some must-haves (Not you Massive!

If these don't work, hang them on the walls.
The other gotchca' OP- besides this foam being less effective and an unknown quality-
It could very likely be a HUGE FIRE HAZORD. Almost certainly (ok, I'm guessing here but..) extremely toxic burned.
Think about that hard.
Then go price fluffy or board fiberglass and the cost to do your own - much of the same work you'll still have to do anyway with the foam .
