Yes frederic, I know what point you are trying to make. My purpose is to illustrate there is no "one design solution" or "school of thought" that is "all encompassing" so to speak. Take a look at the different types of control room design that was "thought" to be the "real thing". In the late 60's, it was "soffit mounting" of monitors and BBC's research into fundimental acousics, in the 70's it was Hass' reflectors, splayed walls to STOP STANDING WAVES, and multitracking advancements, in the 80's, rear wall diffusion,LEDE and RFZ, the 90's brought slot resonators to light, and to the dismay of some(me

), the thought that LEDE DOES NOT work

and small room diffusion is a misnomer even though accredited acousticians and scientists who own companys who manufacture them SAY it works. Now it is splayed walls, NOT for standing wave illimination, but for reflecting frequencys with RAY charachteristics, as low frequency is NOT directional, and BASS traps, not formed from long PANEL absorbers, but resistive absorption HANGERS, corners covered with rigid fiberglass and other types of ABSORPTION products, such as RPG makes. What bothers me, is todays design dogma, is tomorrows dump heap

and what has been presented, EVEN in scientific acoustic books as the "holy grail" ideolgy of the current studio design thought, is discarded as so much rubbish tomorrow. I spent a GREAT deal of time trying to discover the science of diffusers after Everest's book illustrated them as the "magic bullet" in control room design, only to have another acoustician tell ME, that HIS interpretation of these designs were totally in conflict to his education in classical acoustics, and he could NOT believe, this was a book on acoustics. So you tell me.
