Room Acoustic Improvement Advice

Hi,
 
Referring to my room picture - https://photos.app.goo.gl/NKB43sxdCXzNUrMW9 & GLM file.
 
My room dimension is 416 x 276cm / height 277cm with no acoustic foam installed.
I'm using a pair of 8351A, placed on a 1.2m tall stand in 60 degree, 5cm from back wall, distance btw the 8351A is 1.4m.
7360 is placed in between 8351A, slight to the left, against back wall.
Crossover is set at 100Hz.
My sitting position is slight inside the triangle.
 
Questions:
  1. How can I improve the dipping on the 7360 at 50-60Hz? Acoustic foam / PSI AVAA?
  2. How much dipping in dB consider a problem?
  3. Is the slight dipping above 100Hz matters?

Thanks

Eng

i think you should have the speakers firing along the longer axis of your room.

desk facing the window. that should give you similar dips on both speakers.

but getting a small concrete room like yours right is a huge challenge.

rockwool for the sidewalls would be good, suspended abfusers for the ceiling and rear wall.
