Here's an online calculator you can experiment with. I entered your "golden ratio" numbers but you can of course change them and see what you come up with. Look at some previous recent posts for links to other useful sites for similar question as yours. amroc.andymel.eu/?l=700&w=470&h=290&r60=0.6Cheers, Rock

Sure, to some extent as it will measure frequency response. You don't want any or as little room reflections as possible, optimally only the speaker. In one of F. Alton Everest's books, he suggests a substitute for an anechoic chamber by using the outdoors during a still, quiet time. Preferably, you would be on top of a hill or a slope with the ground dropping away from the speaker being tested. But if it sounds OK, you probably did not damage it.
Last week, I got a Alto Truesonic TS210 550/1100 watt powered speaker to use as my stage keyboard amp/speaker combo; it's only 20 pounds! (I finally got tired of dragging my Peavey KB300 up and down my basement stairs). While I was testing it out, I thought I heard the tweeter making harsh resonant sounds on some sustained notes at full power. I stuck the offending organ key down and walked around the room only to find a decorative temple bell zinging away. (I can get all sorts of stuff to rattle). Moral of the story, don't blame the speaker until you eliminate all possibilities.

Dovis, Yes, two way (or more if you want to include iso booths) CCTV visual communication system (no windows). Cameras have pan and tilt so seeing what you need in the studio should not be too limited. Sure, it's not as intimate as a window but might be much less expensive but you need to do the numbers. If you're designing a big bucks studio, the window is probably "required" possibly because "that's the way we've always done it" As far as harsh reflections off glass, I don't know of any specific reported problems but I'm no expert. As far as proximity of far field monitors to edges, eliminate edge offsets and keep the glass pane in the same plane and flush with the wall or as flush as you can if you think that will be a problem but it probably depends just how extreme the offset is. Small dimensions offsets will probably make small errors if any. My best guess. Cheers, Rock

I'm inclined to agree with Hex but I'd also suggest checking with Rod Gervis' book if you can get your hands on it.
If you're concerned with #2, why not consider building the CR wall the same thickness as the window? I believe it was in Rod's book that I was surprised to read that proper window construction exceeds STC of typical wall construction so if I read this correctly, the wall could use thickening up anyway.
Another idea to consider is wide-screen/camera system. The advantages may outweigh the disadvantages depending on your situation.
