this layout is very similar to a layout i originally gave to erskine as part of the consultation process before i contracted them! talk about going in circles...
I'm actually looking at a very similar setup, although I'm leaning toward a flat screen.
What made you decide on curved? Are you using an a-lens? Which one?
A-lenses are a bit complicated on those projectors.
With a 4k signal, they won't do the a-lens stretch without external scaling.
With a 2k signal, they will do the stretch, but there isn't a significant brightness gain, due to the change in zoom and the projector's aspect ratio.
I came to the conclusion that due to the specific Sony issues, no lens was cheaper, much simpler, and a bit better quality.
A higher gain screen means tradeoffs.
You'd have to go to a microperf screen.
I've never seen either full size first hand. I'm just going by what I've read.
XD is the highest gain weave.
The microperf screens create audio concerns, particularly with a curved screen.
There is a decent amount of extra cost and complexity in order to buy the screen and combat that stuff.
Also, apparently microperf pattern is more visible than the weave.
Anyway, I'm leaning toward flat XD 140" 2.35. As long as 3D is 16:9 and not using an a-lens, I think I'll have okay 3D brightness, although not ideal. I'm sure that most of my viewing will be 2D, so I'm not terribly worried about it. It sound like the most practical alternative to that is actually using a separate projector for 3D. I guess I'll look into that if it's a major concern later (unlikely).
Were the 4x surrounds + 2x rears he was recommending dipole or monopole?
Since they are so close to the seats, it's possible that dipole would be good the feeling that the speaker is too close to you.
I got speakers that were switchable between dipole & bipole, and I found myself preferring bipole.
I had just heard that when using multiple sets that monopoles with controlled directivity was best.
I think dipoles are more prone to crazy cancellation problems than bipoles when using multiples.
I'm not an authority on this stuff, so perhaps someone could make a better recommendation.
