Steve and Bert,
THANX for the clarification! In browsing around the web over the last few weeks, I've seen a few... repeat few, control rooms that are splayed at the ceiling and tapering down to the top of the soffit mounted speakers.
I read about, but no pix, of one studio that mentioned that there was "acoustic treatment" on the front wall which only allowed viewing into the tracking room as there was no place to sit in front of the console due to the shape of the wall.
I thought it rather odd as many of the classic Manzella and Berger designed (patterned) rooms are pretty well known for the classic sofa in front of the console sized control room. (although I'd suspect that it makes it a royal PITA to service a console)
Steve, I'll see if I can find a copy of Newell's book on Amazon.
One question that keeps knawing at me is whether I've allowed enough space between the CR and tracking room to do a proper job of soffit mounting.
