... really do not know enough about the equipment at your disposal. However a few more factors you might need to consider Brian.With a projector you are limited to the angle which can be used. We have a very large cathedral ceiling so a projector hanging down would have looked obscene and would have required extensive engineering to make the ghastly cradle. So we put it on the floor and had a table top made (being very careful not to restrict ventillation). I'll email you a photo. Anyway, the bottom of the screen could only be slightly above the projector lenses. If a unit iss mounted from the ceiling the reverse holds true - the top of the screen can only be slightly below the bottom of the lenses.
The second vital factor is the resolution of the projector. This varies a lot even within makes with progressive scan, line doubling etc complicating the scene even more. A large screen is great PROVIDED the playing and projection equipment can give a quality picture. As you can see from the file I sent you the 6X factor is what applies for us using a EMD110-HD Stewart screen 96" x 54" in 16:9 format. This gives us varying results depending on the software and was certainly the maximum we could have used.
The 11X factor is one quoted in the latest TPV as one which applied in the past but can be improved upon with current gear.
One final thought re your excellent Maggies. Why feel confined to having a rear projection TV against the wall with speakers right next door? The RPTV could be out a bit from the wall with wall shelves behind as we have done and the Maggies a bit further to either side. A centre fill speaker might be necessary (difficult to match to the Maggies I know) but I bet that would work OK. Besides, if you have a screen on a wall you will have the Maggies in a bad position will you not? I understand they are like the electrostats we use & need space behind.
Nuff for now as I'm not sure I'm helping.

John

First issue with these types of situations is you need to be able to darken the room to a near "black" level. Hard to do in "relatively" sunny Texas, especially since you said a living room. I would look into some professional installers, who are ISF certified. They should be able to give you some information. I would also look at the last few issues of Stereophile Guide to home Theater (don't look at the reviews, they are all the same) for setup hints. There is a running column on home theater setup. Hope this helps.
the same amount of room darkening than front projectors?You make a good point against a combined lounge room/HT if you want to view during the day. Generally we do not althoigh can blacken the room effectively with outside roll down shutters if required. Incidentally these shutters are insulated and offer excellent protection from heat, cold and burglars!!!

I don't think so, but even a regular TV looks better in a darkened room. Please note you should have a bit of amibenent light for a monitor.
