Update: I've uploaded a picture to give a better idea. Sorry for not making it easier, being this is my first post and all . I'm using a spare bedroom for my control room/ studio. At this point it's not treated at all.
My current thought is 4 - 2 x 4 x 2" thick traps covering the wall behind the desk with either super junks or just thicker 2x4 panels. My question is regarding the use of bass traps in the two front corners. Because of the layout with a large window on the right (covered by blinds) and paper/cardboard closet doors on the left, would I treat this as a standard corner? Both superchunks would obviously obscure parts of the closet and window (which I'm OK with). For the sides I was just going to hang 2x4 ft panels over the window and closet doors.
Thanks for any input. EDIT: Added a picture to help.
