Need opinions on ceiling reflections

All,I have a soffit that is running length-wise on the LEFT side of the ceiling (picture in my system). The ceiling is 8' and the soffit part drops down about 1'. The speakers and sound panels are positioned with a precision of 1/8th of an inch and it sounds amazing - especially on the RIGHT side. The music appears to come from way back and way outside the RIGHT speaker and you can actually "look" that images of various instruments playing in those empty spaces. But I have a heard time "seeing" those images on the LEFT side speaker. I have a feeling that this issue happens because the reflection point on the left side ceiling is a foot lower than the one on the right side ceiling. I was planning of getting some acoustic foam and attach it to the ceiling using T-pins (since it is a textured ceiling and foam tapes will not work). I assumed that this will absorb the reflections and could work on restoring the proper timing/clarity on left side.

Could you guys weigh in and let me know your thoughts? Please feel free to let me know if I am off and the issue is completely different.

Gentlemen, Thank You for the various suggestions. I will start looking into getting the Owens Corning 703. Thinking of 2' X 2' X 2".
@noromanceĀ the idea of symmetry is nice. But like I said, the RIGHT side has absolutely no issue. So I don't want to touch something that is working fine.šŸ˜€
@mijostyn currently I have no plans to change the speakers.
@hild45, I had taken a look at ATS site yesterday. And I see that you have their OC 703 panel. What did you use on the one panel that is flush mounted on the ceiling?

@milpaiĀ  My wife sewed a pillowcase for a panel with a good acoustically-friendly fabric. It fits tightly but there is a bit of slack. I stapled it to the ceiling. There are mounting brackets and nicer ways to do things, but since I needed to see if it would work and how it would sound, I started in with a prototype-first mindset.Ā

On the ATS Acoustics site, I found the "ATS Acoustic Ceiling Panel 24 x 24 x 2" ceiling panel. But this is not OC 703. The specs indicate "Knauf Board with ECOSEĀ® Technology". Anybody familiar with this? What is the difference compared to OC 703?
