What is it with 12 degrees?

From what I have been able to gather from here and elsewhere, it seems that 12 degree celings, and or walls set 12 degrees off of the perpendicular seems to be ideal? I understand about non-paralell-ism (to coin a word), but I was curious if a smaller angle, say 6 or 8 degrees would work as well for ceilings?
 
That seems like a bit much to me too - I just drew that angle in my cad program, and at 16 feet you have over 3'5" offset compared to zero degrees. I would think that the elimination of flutter echo wouldn't take that much - I know modal response doesn't need that much difference to be smoothed out. All the rooms I've drqwn trying to find a workable studio complex, I keep coming back to rectangular when I look at all the wasted floor space. Maybe just built-out ceiling diffusors, ala Everest's earlier "12 studios on a budget" book. Man, 3-1/2 feet lost in a 16 foot wall? Rather spend $2k on double 4" auralex... Steve
 
Yep, that sounds about right. I was looking at a 2 foot loss in 10' or 8' ceilings down to 6' at the end.
Assuming a 20' square room with the angled ceiling split in the middle would yield:
tan12deg=x/10
(tan12deg)*(10)=x
x=2.16'
 
Yeah, except I wouldn't want a square room of any size, unless it was big enough to divide into two acoustically useful ratio-ed rooms - Seems to me that smaller rooms don't really have the luxury of splayed walls/ceilings - even medium-sized ones might be better just splaying the sides/ceiling of the front half, then diffusing the rear with book shelves, 4" foaming the sides for flutter, and spot treating with a laser and mirror - that should get a sorta RFZ for mixing. For tracking, it would be a whole different story depending on what instruments you record, what style, etc - Everest's "dial-an-absorption" concept of hinged wall panels make sense - I think I saw some similar on SAE . Those and some poly's would probably make a 10 x 16 x 23.3 room pretty usable. Around here, Home Depot carries these "cottage stones", usually sold for making low stone walls, they're either trapezoidal front or just radiused, kinda rough - Been thinking about those floor to ceiling as a rear wall...

I wouldn't want a square room either. Those are just nominal dimensions. ;)
