I'm 13'6" feet back from my screen, I see your front row will be 10 feet away. I assume you have done your homework and that distance will work fine with that size screen - man talk about full immersion into the movie, those front row viewers will probably have to move their head, not just eyeballs, to see anything but screen.
Ahhhh, it took me until 4pm today to get my AVS fix!! Damn meetings!!!
The diagonal on a 200" wide(16.6ft) 2:35 is 217". The eyes in the first row, as it sits, will be like 13' off the screen, so just less than 1x width...I may still inch the first row back a bit, but am considering all options. The second row is where my seat will be
I kind of like the idea of the first row being where it is for the kids to look up and "ooohh, ahhhh" type effect, but the 2nd and 3rd rows will be the real winners for sight and sound I think. I may push the front row back two more feet if I can without moving the 2nd and 3rd back much, if at all.

And dang, you guys are aggressive with your screen sizes. I'm planning out my false wall now, maybe I should step it up. I thought I was getting crazy going to 130" in 16:9. I'll be about 15' back in the primary seating position.
I can't feakin wait man!! I am so consumed by it right now just waiting for everything to go. It's gonna be even tougher when the 18 TD15M woofs show up in a week or two, and the BMS/SEOS24s after that.
I just come from the school of thought that you should go as big as is managable as long as the seats can be moved back a bit if ned be. To me, it's all about the room width...I didn't want to have a screen wall that was as much wall as it was screen. If the 130" fits nicely and you like the size, go for it!!

My experience (I don't have scientific support for this) is that having all the speakers behind the screen is not important as much as having them on the same horizontal plane is important. You might notice some more width, but I don't actually feel that it is wider with my mains in the corners vs behind the screen.
There might be some advantage to having the speaker behind the screen but IMO the advantages of corner placement trump that. Parham has some good writeups on the advantage of locating in a corner. I think that the best way to deal with early reflections is first by reducing their prevalance and second with absorption. The closer you are to a corner with a controlled horn the less early reflections you get. The horn effectively becomes much widerband.
IMO, the worst reflections are the midband ~500-3000hz near wall when speakers are 3-6ft from the sidewall and pointing straight out. The horn won't help much with that. Lots of midbass response issues are due to this typical placement as well. I think that with the typical messy directivity speakers people use it is hard to find good locations short of pulling your speakers 8-10' away from walls. Instead they just put them where it is convenient.
Here is an interesting post by Parham about speaker placement: http://audioroundtable.com/forum/index.php?t=msg&th=16684
Edit: When I say "I personally like it" I'm saying I like both the measurable effect and the subjective result. The measurable effect is basically a cleaner response. Early reflections create response issues.
I am going to fully unitlize DE for sure! I am just waiting on him to get the final contract back to m , as we made some changes to the scope of service. The nice part is that we will have a fully AT screen wall, so we can certainly experiment a bit..( as long as my wallet can handle Dennis being there :)I am going to check out the link you posted as well, thank you My mamain concern will be for even coverage, or as even as possible.
On a side note, I paid Nathan Funk for one of his DSP amps today to try out on a Dayton 18 in the living roomand see how it compares to running them with the cv5k or ep4k
