I guess I'm a bit confused. Do you think the AT screen no longer makes sense, or is it the two rows of seating that you don't like in this space?
I realize that audio performance is only really going to be good in 2 or 3 seats, no matter what layout I choose. I think that's almost always the case in a room this size. 80% of the time, there will only be 1-3 people watching, but for that other 20%, it would be really nice to have seating for more people to come over and watch as well. Will they have ideal audio in their seating position? No, but at least they will be there, and most people won't care nearly as much as you or I, they'll just be wowed that there is sound coming from behind them. And I'd rather plan for an eventual 2 rows than a permanent 'L' shaped seating. You're right, it just wouldn't be the best way to do it.
HVAC isn't a big issue, the trunk lines are immediately on the east side of the wall with the joists running east/west, so I'll be able to add 2 supplies and a return, no sweat.
With the AT layout, I could put a slope on the opposite corner as well, but I'll never be able to get them to match each other because of the dimensions of the room, that's just an unfortunate fact.
Alright... Giving your post some thought, I'm trying to center the seating a little better. I've realized a few other things:
1) The couch models in the program I am using are extremely wide. I narrowed them down to more realistic dimensions.
2) I seem to have mis-measured the opening on the left, I finally have it right now.
Which leads me to two 'final' layout choices:
Standard layout, not worrying about the asymmetrical corner:
And now with the new corrected dimensions, there is indeed enough room for a door on the side, keeping things symmetrical, in an AT layout. I'd just have to find an alternate location for my AV rack:
So, given that I do want two rows, and I do have room for a side door, what are your thoughts? Thanks again for the help!
