I'm gonna be starting work on my cinema in the next month or so, so I'm finalising my 3D sketches and I've hit a hurdle. I'm no acoustics expert, I've never dealt with anything like this before in my life (I have the basic down thanks to AVS forums). Now I was wondering, which design would be best (see attached pictures). They would be filled with as much rigid fibreglass/rockwoll/whatever as I can squeeze in. I'm also open to other suggestions.
