check my design please (png)

Hello,Unfortunately I cant change disposition. Hoping for your 0.02$ : ) I know that the measures are not good but..here we go anyway. I can not change disposition. This is just an idea: I still have to make acoustic measurements (and I will) L=3,85M L= 3,95M H=2,75M --> important-->The walls = are already internal old treated - no ceiling - with rockwhool (I don't know the density, I gues very high) covered with plasterboard. Speakers = Adam A5x (maybe one day a sub) Door = massive door treatment with isolate + absorber materials + seals RedLines = Basstrap fiberglass very thick and low density I want to put Black line left = huge tent very thick & "breathable" Black line right= Speakers on stand Bookcase = (100% filled of books) I want to fill the 25/30cm behind the the books with fiberglass as well -> section = |fiberglass|books! Sofa = I will fill the whole sofa (also under, behind etc) With fiberglass as well. floor = will add rugs on floor even more fiberglass = fill any space, eg between bookcase and wall, between the sofa and the wall (even under sofà) etc., with fiberglass. ceiling: rockwhool and fiberglass mix traps . Many and big. Going for an angle from speakers to the rear. that way speakers < rear (angle) main concerns: the door and bookcase in the first reflection position. Sorry for bad graphic!

There is an announcement at the top of the forum with the forum rules about what to do to assure getting as many responses as possible. The announcement leads to this post (click here). Actually, several people, who are experts on this forum, will most likely not reply if you don't do what is written in that post. Please check those rules, as you seem to be missing some things! :) - Stuart -
