The trouble with my studio

[Caiwyn]

I'm getting ready to pick up some bass traps, and I'm trying to decide exactly how many to get. The trouble is, my studio is a little irregularly shaped (see the attached image, below).

The blue section is a door, the yellow denotes the window. As you can see there's a closet in the bottom right corner of the room. I have removed the doors from it so that it's totally open, like a little alcove, and part of the room.

The upshot is that I technically have five corners in the room. Do I need a bass trap for each of them?

I know I need to put traps up on each of the four walls where the wall meets the ceiling. I also know I need four more, one for at least four corners of the room. So that's eight so far. Do I need a ninth one for the extra corner in the closet?

I'd plan on facing North, and putting bass absorbers floor to ceiling in the 2 front corners. In the rear, do the left bottom corner and also try to get something that you can slide in and out of the way for the corner by the door.

Okay, so it's settled that I'll put a trap in each of the front corners, and a portable trap to set in the corner with the door.

You said to put the last trap in the left bottom corner... did you mean the right bottom corner? That would seem to make more sense to me, but there could be a reason to put it in the rear left of the closet instead. Or should I spring for another trap and just cover both corners?

I'd say, build a stud wall with a heavy door where the closet is/was, and use it for a tiny vox/amp booth. Then you have a symmetrical, rectangular room to work with and install the standard placement of treatment. I'd say even 4x2x4" in the corners, 4x2x2" in the first reflection points and back of the room, with 4x2x2" in the vox booth, except one 4x2x4" spaced a few inches from the wall, as shown, to provide better bass absorption.
