You would have much greater results using OC703 cut in triangles for the corners A 4'x2' panel would yield 4 trangles.Then stack from floor to ceiling.

Did the NRC ratings you look at specify the foams rating by Hz? If not its not very useful.

Whats the absorption rating at 80hz and 40hz? Thats where most people cross their sub in and in the middle of its bandpass respectively.
