Acoustics experts - a little help please

Room acoustics is a complex matter...

 I had no experience as a serious acoustician in many room with many different problems...

 I know how to learn what we need to solve a specific problem in a specific room...

 Consulting a serious acoustician will help you...

Or do as i did but it takes much time so much most did not have the luxury to do it ...Read articles, books, and do your own experiment in your room...It was the best fun in my life...

I cannot advise you without being myself in the room and experimenting...I did it mechanically with my ears...

 A pro acoustician can give advice very useful for your specific problems...

 The best soundstage i heard was mine in my first dedicated room, but the tuning takes me 2 years...

 I apologize to be of so little concrete help....

Looks like you need sidewalls and ceiling treatment. Front wall treatments don't really do much to control early reflections, as these are the ones that need the most attention. 

I apologize to be of so little concrete help....

why now?

Because he need very concrete and simple solution...

I cannot give them without being there and experimenting...

If money is not a problem, the best solution is Dr. Choueiri  BACCH system....

why now?
