I'm just about done the drywall (arggg). I'll post some more pics over the weekend. I decided that a single door would be better at the entrance. I will be able to mount the rear surrounds better, a single door is cheaper, and a single door is easier to apply soundproofing to.
I will be using Safe n Sound doors on all and applying seals and thresholds at a later date. Since I went staggered stud, all the openings are 6" rather than 4" so I have to custom frame instead of buying prehung doors. I could probably have them made but at an added expense.
