Sometimes I love a HUGE image for some movies and for some levels of source quality, other times smaller images look better. And I want the flexibility of having a much bigger 16:9 image than I'd get if I stayed strictly CIH...
I like your thinking. There is a lot of discussion about the benefits of CIH, but after having my setup for a while, I'm of the opinion that bigger is better, no matter what the aspect ratio. In my case, my room height was the limiting factor, but I could go about as wide as I wanted, so 2.35:1 made sense. In a room where the width is the limiting factor and you can go as tall as you want, then I agree that it makes since to go with a taller screen as you have done. That lets you get the biggest picture possible (if you choose), no matter what the native aspect ratio of the movie. I sit 10 feet from a screen that is a little over 10 feet wide in 2.35:1. I love it. When I watch a movie that is 16:9 or 4:3, I feel it is too small. In these situations it would be nice to have a bigger picture if I had a taller room.
In your case, a 4-way masking system is more important than ever and I think your plan of the Carada/Goelst system combo will work well. I like your mock up drawing. It looks very good. I agree with your plan that a bevel on the side masking that rides close to the screen is good idea. Overall I think you have a very good plan, and at a cost of $5,000, compared to $19,000, I would probably make the same decisions as you have made.
My humble attempt in this thread has been to try to show an option for people looking for ideas to do a DIY manual masking system in the $500 range. In my recent attempts to motorize my system, I have been hoping to keep the motorization below a couple hundred dollars. My system is pretty labor intense and I realize this is not an option for everyone.
In all honesty, I have not intensely looked into the commercial systems that are in the price range you are looking at. My off-the-cuff thought when I first read your post was that if I was spending $5,000 + on a system, I would not want to mix components from different manufacturers. However, if a complete solution is in the $19,000 range, then I completely understand your choice and think it is a very viable plan. Your drawing looks great.
Uh oh... Now I'm thinking about those 19" panels on each side of your screen.... If you ditched those, you could still have your 61" in height, but get a 2.40:1 screen that was 146" wide instead of only 124" wide.... ===> now you're talking big...
(Just playing with you... I like your plan, -- but I would take another look at the SMX option before making a final decision
