room setup

Before answering, how easy is it to move the window?

lmao
mc you never cease to amaze.
 I've been reading these forums for years. Many moons ago you made the statement "everything matters" those 2 words should be at the forefront of every topic.

I would not know the answer, but want to point out that you can disguise heavy drapes or sound treatments into the wall with the window much easier than the other wall(s), in case that matters to you. My speaker wall has a 6-8ft wide window that takes up most of the wall, with thick, heavy drapes that definitely makes a difference in sound quality. 

Good luck
