Sure, I will PM you my contact info.
Yes, if I was demonstrating 2 channel in the room I would have likely arranged the front seating in the way you're describing with seating dead center in the front row. I would have also needed to move the front speakers into the room itself. My projects are almost exclusively automation and dedicated theater, so my 2-channel clients are non-existent. I really enjoyed my old Magnepans for stereo... it's just not my referal base so I couldn't justify keeping them and setting up a room for it.
With Synth systems we are dealing with separates for high/midrange and woofers with external passive crossovers, so the arrangement is completely different, more akin to commercial cinema where it's done that way.
Believe it or not, the money seats in this room are in the back row.
We placed the mics and did the manual equalization that way. The back row is the ideal seating distance for image quality as the front is a bit too close, so I decided to make the back row ideal for the audio. Since the majority of the seating is in the back row, it made sense to calibrate for that portion of the room. Honestly, that EQ is so powerful that it sounds great in every seat, but the back row is ideal for image.
The projector was originally intended to go inside the back wall, but it wasn't workable due to room size. So the next project is building a hushbox around the projector where it hangs. It's a surprisingly quiet unit as it's the single lamp model. The dual lamp would be too loud for anyone underneath it. The box will be good for aesthetics too.
The PC is only for games and not movies so I placed it behind the screenwall. It is loud enough to where I would normally place it outside the room, but since it's only for Gaming and for me I didn't mind. I originally hoped to put it in the rack, but could not find any rack mountable chassy that could come close to fitting and cooling what I have in that beast. :tongue:
Yep, I'm very familiar with Starglass. We had a project for a huge one (about 200" diagonal) for a living room. That client was in the loan business so I'm sure you can guess what happened to him and that project once the market crashed.
I think I still prefer a Studiotech130 or similar material to the glass (it has a kind of glossy and less film-like look to it), but a lot of clients like it. You just need extra space behind the screenwall for the mirror system and projector which I didn't have in my room.
