That clears up a lot!! Good to know it's starting to "sound" good lol.. Thanks Stuart!
So here is my new attempt for the layout...guess I'm calling this one 11.1
List of adaptations (and a few..ok a LOT of questions):
-I reduced the air gap between the inner walls from 15" to 12" (this gave me an extra 3" at the top of the control room so I pushed out the right wall another 3" to compensate for symmetry...this also increased the time for the first reflection to 17.45ms woohoo
haha)
-The line of sight between the control room and live room is now slightly more "on-axis" with the top left corner of the live room. This was another positive result of reducing the air gap. It pulled the glass over and up to the right a bit. Can't complain about that.
-I added a sliding door between the control room and iso booth.
-I also added a 6º angle to the sliding doors/walls. For some reason this looks very awkward to me and I can't figure out what I may have done wrong. I know 6º is not much (is it even enough?), but with those 2x6 studs it appears to be very steep. Is it possible to angle the glass without angling the walls? I'm losing a decent bit of space in the booth by splaying the walls like that.
-I went with a 76º intersection point at the mix position (38º speaker angles just seemed more realistic than 37.5º).
-The front of the baffles turned out to be 4' 5 1/8" wide. I just extended them all the way to the drywall around where the glass framing would start...is that ok? Glenn's drawing (as well as my past few drawings) showed some kind of extension between the soffits in front of the glass...is it critical to join the two baffles (L and R) across the top and bottom of the glass like that?
-There is about 5' 6" between the front wall and the listening position (given the intersection point is 18" behind the engineer's head, per Glenn's advice)...does this seem about right or do I need more space there? I do plan on buying a console/desk somewhere down the road...
-I read that the monitors should be positioned at a point that is 2/5's the size of the baffle width (rather than centered in the baffle)...is this referring to where the center of the monitor should be, or the side of the monitor? Wasn't really sure what to do there...
-After ray tracing out to 55º on both sides of the left monitor, the only path that is a first-reflection "problem" is the one that basically hits straight off the right wall and reflects back to the right ear. This is the path that I calculated having a distance of 25' 11 3/16" from which I subtracted the direct path from speaker to ear which was 6' 3 7/16" which gave me a difference of 19' 7 3/4". I turned that into decimal form (19.64583333') and divided it by the speed of sound (1126ft/sec) which gave me .017447 seconds. I multiplied that by 1000 to get the milliseconds and as I already stated earlier that turned out to be 17.447ms.
Whew that was a lot of numbers...anybody out there wanna check my math??
(granted this is dependent upon whether that little circle is accurate to the size of a human skull...of which I did not measure)
-Does it matter that one of the 55º rays from the left speaker bounces off of the right baffle before heading towards the right wall (and obviously vice-a-verse)?
-Ok I think this is my last question for now. Do you think the door going into the control room has enough space on the right side for proper/substantial framing? Stuart I know you recommended against the superdoor but I want to keep my options open. I will be getting into more of the detailed budget pretty soon and if a superdoor ends up being cheaper than double doors, I might go that route. I just want to make sure I'm allowing for this possibility if it were to be a money saver. I've provided an image of the section I'm referring to.
And finally...I'm sorry for such a long post! I just had a lot of things I wanted to cover. And again thank you thank you thank you for everyone's help...I would definitely be ramming my head against walls by now if it weren't for you guys. And Stuart... you tha man!!!
Cheers
