Some very nice stuff here. One small quibble on the nature of deep bass: most of those vibrations are pretty much immune to casual room treatments (below say... 60 Hz). This does not mean that this foam is ineffective, but that the SOAF (significant-other-acceptance factor) may be of greater importance when the material is placed.
Thanks for the link! Writing for myself, my present need is low, but knowing such a source is a very good thing!
