I have 14 acoustic panels around our studio - 2 inch thick roxul mineral wool. Works well. The backplane is made of a thin (1/8 or 1/4 inch thick) wood.
My question though is, would one or two layers of MDF be more efficient/useful as a backplane vs. the thin wood? How about an MDF sandwich, with material in between two layers of MDF, say, 1 inch thick roxul mineral wool or
some other acoustic material? Just curious if there would be any benefit to this approach.
