Hey guys, thanks a lot for your input.
First of all, the walls aren't up yet. The bottom-middle void is not a closet but the stairway that connect the 1st floor the the garage, so it's not usable.
I could always make the rack closet bigger to have a more rectangular room.
I wouldn't mind going for a big 160" AT screen, but I don't want to drop $20k on a Runco pj. Will a RS-55 have enough juice to power that?
My speakers are probably going to be Atlantic Technology 8200e series. As for subs, I didn't make up mind yet between SVS Ultra-13s or Funky Waves.
As for the number of seating, I want to have at least 8 chairs.
