Hey Gar,
I share your interest in the placement part of this. I can't attest to this specific instance, but I went through a round of experiments with my Theater Fours. I tried stock first, then both sides + back & bottom. The best thing I tried was when Wayne was talking about fiberglass working better at the frequencies of interest when spaced away from surfaces. I put a blanket of glass on a shelf brace about 10" from the top, now the midbass is so clear and stiff. The worst thing I tried was too much or too thick a material(clear sound, but spongy on kick drums & toms). I ended up with stock plus the brace blanket and a little piece on the unlined side about 12 x 8 right next to the driver. The Little piece seems to help the mids, but It is not something so blatant that I would swear on it. The bisecting blanket however is serious goodness.
