I completed the wall traps building furniture grade wood framing and am thinking about full wall length traps to cover back wall. I have planned a 3" 703 (three panels) 24" running up the length of 88" and complement that with the same at 12" on each side for aesthetics. I need early reflections on both side walls and something behind the monitors without a doubt.
I understand that the monitors and desk need to be 6 feet from the wall but that isn't happening in the 12'X11' bedroom.
What are your thoughts on additional treatment before I go out and cut more lumber and panels?

My first thought is that you are oriented the wrong way unless the drawing is not to scale. The front wall should be the left side wall and the desk should be set back a few feet from that.

There may be very good reasons why you can't do this but I'd have a re-think. You don't want your desk (and speakers) bang up against a wall.

That room is pretty close to being a cube. I doubt re-orienting 90-degrees will make that much difference.

If you flipped your layout 180-degrees you would have traps in the corners on both sides of your listening area. I think that would give a little better result than a single corner trap on one side only.

You should notice the difference backing that desk about 2-feet away from the wall and putting some treatment on the wall behind the speakers.
 
Yeah, a foot off is still pretty square. Tough room. Is the square over/around the mix position a cloud? That would help and even if you can only pull the desk and speakers out a foot off the front wall you would like the result.

One other note - you show 1 and 3 inch absorber depths. What material are you using? OC705 @ 12pcf is effective at those thicknesses but 703 and Roxul at 6pcf is normally 2 and 4 inch thicknesses.

*edit - I see you mentioned 703. Have you bought it yet? Can you go 2" and 4"?

Glad I looked at this thread. Learning loads for my own little hole in the wall.
 
Thanks for all the insight, so far. All is greatly welcomed!

A. This bedroom is designated as my studio/ music room and moving off the wall 2’ is not an option unless I‘ll only mix here. I can go 1’ and loose the space.

B. I’ve received ($$$) 6 1” OC 703 panels and used 4 to make a 4“ standing floor trap about 18 inches off the floor.

It took up too much space so I can use them on top of the other 2 panels along with 2 additional 1” Johns Manville 800 duct boards, trimmed to 88” on top of each other to make a 4” 24”X88” center, full wall trap. I’ll wrap this with material and use a 1”X4” frame on the back with 2 ½ holes drilled for air. That’s better than direct wall mounting.
This is what I planned before I thought to post here and not continue using material before I had better direction.

I’ve already built the corner trap frames and cut panels at 45` angels for these at 6” depth. They’re 46” bottom frames with a shelf and a complementing 46” upper frame with holes to mount 20” higher totaling 112” to my crown molding.

C. I have an “in” with a local AC company and drop by to pick up scraps from them building ac ducts. I carry out a truck bed full of assorted sizes of 1” and 1 ½” JM 800 series panels. They mostly range at about 45” lengths. My problem’s been making use of them without much waste and matching them up. I must have about 20 panels right now.
 
Oh... ps
the back of the monitors are already 8" from the front wall now.
I can mount traps behind the desk.
