Control room window&30 degree basstraps

[cmick]

As I start to rip apart my house, I am very glad I wandered upon this site. My question is, in building the wall between the control room and the live room should I bother trying to frame out the 30 degree basstraps. Or, should I just concern myself building a soundproof wall with a window, and then add the angles for bass traps, larger monitors and a TV later.
Also, the control room is looking like it's going to be 12 by 15, with 9' height. Does anyone have any experience with this size, and have any comments or design ideas?

Thanks in advance, and I'm sure I'll be a regular guest here. Only wish that I'd found this site sooner.
