I have added another 120mm trap yesterday but have placed in the backwall-ceiling corner now.
Only got 1 up in the left uper corner but will will build another 1 soon.
Just made some tests again exactly just at mixing position (measured distances and what not for accurate info. Mic pointed to forntwall at 115cm from tweeters and 115 off ground (measured from mics tip to tweeter/floor).
As you'll be able to see it's kinda steady above 200hz but below that it's a huge mess.
Treatment at the moment exsists out off 2 front chunks floor to ceiling 150mm thick fluffy insulation crammed in the corners, 2 120mm traps at reflection points, 2 60mm thick traps right beside me each side, and that 1 trap in the backwall-ceiling corner.
I also have to mention that 100 and 150 hz realy seem to be powerfull at mixing position only....that area is like a box isolated with problems bellow 200 hz.
All input is greatly appreciated and i believe this issue is a real test.
Since i have spend a day doing a million things which i can think off anyhow.
Once again thanks for all the help !!.
