Thanks for the tips! I just hooked it up on Sat, so I still have a few things to test out. Good to know that the iris doesn't appear to be anything to be too concerned about. I'm impressed so far with how well it looks even on a dark beige wall.
LOVE!! The iMIKE THEATRE Great Job!
I'm looking to do something similar, but I don't have a uniform enough space to optimize the sound that well. I'll be putting in a bunch of bass traps and reflection reducing wall art to make up for some of the strange spaces. I do think I'm putting in in a second tier as well. I'm also in the GTA, so I'll have to check out UFW for some furniture, it looks good.
I'm painting my screen and insetting my speakers on "built-in" shelves on each side...not in wall speakers. I think it will turn out really well, but I'm sure not quite as "theatre" as yours.
