Rear wall effect on sound stage location?

I have a large listening room (18W x 30D) with cathedral ceilings. My speakers are Vandy 2CEs placed 8ft. apart and 4ft. from the front wall. I sit about 9ft. in front of the speakers. I get a great wide and deep sound stage with vocalists/instruments that appear to be behind the front wall and slightly above the speakers. I am very pleased, with no complaints.

However, in many of my friends listening rooms with rear walls much closer to the listening area, the vocalists appear to be more even to the speakers or even in front. Does anyone know if the location varies with the closeness of the rear wall? Do earlier reflections pull the sound stage in? Where is the most desireable location?

"Center stage" will ( or at least "should" ) vary with each recording. While a lot of what you hear is based on room acoustics and the gear that you are using, spacial cues are derived from the source material and the way that it is mixed in terms of frequency response. For instance, a female vocalist that is recorded "loud" with a lot of upper midrange will sound closer or more "forward" in the soundstage. The same singer recorded a little quieter with less high frequency content to her voice will typically sound more distant or further back in the soundstage. Obviously, frequency responses of a speaker / room can alter this quite a bit with "peaks" and "valleys" playing havoc. This also has to do with delay and arrival times, so it is VERY complicated to say the least. I wish i had a set answer to give you, but you've stumbled onto one of the things that explains why some systems sound so different than others. Sean
