I think you may have your mixing station oriented the wrong way in the room. The speakers should be firing down the long side of it.
Your problem, dimension-wise is that the room is almost a square, so any modal issues are going to be multiplied. The roof height is ok, as it's not the same as the length or width.
Your best bet is to orient the station correctly. Center of the room width-ways, and 38% of the room length-ways (the mixing position that is). After that fill each of the corners with as much rigid fiberglass, rockwool or polyester insulation as you can afford. Superchunks are the word. They work way better than any other kind of broadband traps for low-end. In smaller rooms like that you essentially have way too many peaks and nulls to do targeted, tuned bass resonators, and even if you didn't, the resonators would take up way too much space within the room itself.

Why are your panels on the floor? You need to get them up higher to stop sound coming straight back at your ears. I'd also get something behind those speakers. Also you can't use a mic like this, you need a test mic.
I have mixing station there because there is no doors. Building 4" thick acoustic panels is my next step.

Those look great, although you might find they are more effective if you uncover the rear of the trap. If you're just using like 5mm board it probably doesn't matter that much though. Great job though!
i´d say remove the back cover...remember, if u space them from the walls where they´r going to be installed by the same amount (5inches) it will double their effect, which is of course better.
the cardboard will act as a barrier for the soundwaves and that is not the goal with those basstraps.
the soundwaves "should" pass by the trap, then air gap, then wall, and back to the bass trap and back into the room.
I´m no expert but from what i´ve read this is how to make use of them to your advantage.
there exist traps that are back covered at the back but those are tuned to specific freqs, and some also have some kind of membrane inside that acts to the benefit of bass trapping
they do look good

Any low frequencys will go straight through that board though which is why I say this difference will be negligable. It depends, if the back is for support then leave it but if it's just redundantly sat in there, pull em out and fabric cover them

I have just made a load of bass traps and I must agree with the others who said remove the backing and replace with thin material . If this is not possible
I would cut out large areas of the backing and staple material over these to keep the particles in . Mounting off the wall is also vital , if you do these two things it will greatly improve your traps effectiveness . They look very well made it would be a shame not to get the most out of them .

Cover it with cloth in that case. Any type that you can breathe easily through. Or any kind you can find for cheap, like grandma's old bed sheets.. :Spin:
my observations:
-want to keep the back panels ,ok, in that case there´s no point in leaving the 1 inc air gap cos it´s useless. U would gain if, like i said above, u spaced the same amount as the panels thickness.
- the ceiling cloud seems to me small and very thin, so i think it isn´t doing much service. i would add another panel up there and make it at least 2 to 4 inches thick and suspended by the same amount.
-the front corners could use traping in the floor and ceiling also, because those are the areas where bass builds up (where the 3 walls converge), so maybe that would be an area to adress also, Superchunk style is the common option for this.
-the trap right behind the monitor could be somewhere else meeded...
-your room is almost cuboid which is bad and creates problems...so more traps is always better.
-how are the traps alligned in the back of the room?

There is no traps on the side and back walls yet.
Is that EQ curve bad? I need real measurement mic.
What if i throw these in the front corners

Spacing them 5 inches from the wall wont double the effect. It Will increase the low frequency absorbtion ever so slightly but no way near as much as filling the whole cavity with insulationi´d say remove the back cover...remember, if u space them from the walls where they´r going to be installed by the same amount (5inches) it will double their effect, which is of course better.

uh... what material did you use?
removing the backs will make a difference, and a lot of people drill big holes in the sides of the frame to allow more of the material to be exposed.

Well, you have nearly 15dB peaks and nulls below 200Hz, which means you need more bass traps and thicker ones at that.
A good (read=adequate) and cheap measurement mic is the Behringer ECM8000.
Those sacks will probably be comfy, but not much else, I think. Except if you get big people to sit on them while you mix (people = good absorption).
And yes, that cloud is too thin. Make it at least 10cm (4") thick and then we're talking.
