I've definately ruled out the rear projection system for several reasons, one being that I have Magnepan speakers. Magnepan speakers don't really like to be sitting next to a 'box', aka TV. So RPTV's are not an option.

I've been doing some thinking about room layout. I'm going to build a modified 'flexi-rack' that I've seen on one of the AA forums. I'd like to build it two shelves high and three shelves wide. This way I could have a relatively short (18" high) but wide (6.5') shelving unit that would offer good ventilation, look nice and not intrude into the room. If we put a screen just above that, it should make for a nice looking and symmetrical room layout.

That goes to your next question, screen size. With the space the speakers need (preferrably 3 feet from side and rear walls), and the speakers being 2 feet wide, that means if we have a 16 foot wide room, we can have a 6' wide screen -- 16' - (2 speakers x (2' width + 3' side wall clearance + 1' from edge of screen). I feel that a 6 - 8 foot wide screen it plenty. I'm not going for HUGE size, instead I'd like to have a good size screen with a good quality picture... while at the same time buying the needed side space I need to really get my speakers to sing.

Using your calculations (6 times height), tell me if my understanding is correct:

6' wide screen = 41" height w/ 16:9 ratio.
41" x 6 = 246" or 20' 6"

That seems like a long way back. I was thinking more along the 14-16' viewing distance, meaning an approximately 25' room to give my rear channels some room to sing. Please let me know if this sounds reasonable.

As far as front projectors go, how about the Sony VPL-VW10HT? I've seen it in the $6000 range, which would give me enough room to get a good screen and line doubler/quadrupler (any suggestions?).

And what is this 2.5x something-er-other stat on screens? I understand it somehow makes the images brighter, but how does it help viewing and what is the range I should look at in a room that may sometimes have some ambient light?

Sorry for my rambling...

Brian
