Dennis,
Health Nut is correct that the best for Video is a motorized "non" perf screen as many including me are using. The point I tried to make was that sometimes reference speakers are build quite big and they are recommended to have their "accoustic center" at the listener's ear level (probably somewhere between the tweeter and the midband-woofer). Good dispersion patters help of course to go for that little amount of tolerance.

Now my dream speakers would raise the screeen-beginning height from the bottom dramatically, if I would start with the screen right above them. Good that I cannot afford them [Linked Image from softronix.com].

Some people, including me, feel very uncomfortable when one has to look up too much. It is more relaxing to look right into the picture with at least 1/3 of it below eye level. I would probably like it the most to be able to look right into the middle of the picture.

I would only choose a perf screen, if I could build that double screen system I mentioned, especially to decrease light scatter and sound reflections, I mentioned that before too.

Concerning your phantom center image question. Meridian Digital speakers will render a much more precise phantom image. Many regular high end systems suffer, they image just to big or unclear to work with the picture/mouth movements, due to problems in phase and frequency responce linearity. Room problems play a role here as well.

Of course in a black room, where you cannot see your speakers (mine is quite black), the psycho accoustic will fool you, but not everybody is fortunate to have a black room [Linked Image from softronix.com].
