Surprisingly this issue has an article on acoustics, most of it ref. a book by Dr. Floyd Toole: Sound Reproduction published two yrs ago. The things that stood out to me were, 8" depth for QRD/math based diffusors. 12" depth for geometrical shaped diffusors, reason being to be able to diffuse down to the 100-1,000 hz level. Wow that seems to me to be some deep diffusors, also he likes them on side walls and placed near the surround speakers.
Their is even a DIY diffusor and absorption panel, the diffusor is a 4' long triangle shape, but it mentions you could use a sonotube cut in half.
FYI Dr. Toole is was a member of the Canada's National Research Council for 25yrs and director of R&D at Harmon Int. (home of Revel, JBL, Lexicon, Infinity, etc...). A big chunk of his research went into a set of guidelines/handbood for Consumer Electronics Assc. and the Custom Electronics Design and Installation Assc. (CEDIA).
I hope some of other members check this article out, and post their feedback. Hard to imagine that S&V even had this article in their as they seem to ignore the subject 99% of the time. :text-nocomment:
