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.

Thank You @dekay . This is helpful. I found out that they also sell OC 703. So I will check out the table and decide.

When I bought my 703's it was $67 for the panels and $50 or so for shipping. I learned later that while 703's cannot be found at Home Depot or Lowes, local construction supply companies have them. That's where I'll go to get more, at about 45% savings!

Too bad my recent Google query of Mark Levenson was not as successful as hilde45's )-;).

hilde45, why would you avoid foam? It is inexpensive, you can order it with all kinds of profiles and depths. I use 4" acoustic foam tiles. It has a nice sparkle to it and you can alternate the direction of the grooves creating a nice pattern. It works as well or better than anything else I have tried. The only down side is that it is cheap and people think you have to spend a lot more money to get something that works. Anechoic chambers are made with acoustic foam. I have never seen audiophile acoustic anything used in an anechoic chamber. I can hear it coming, "that's not the same as treating a room." Heck, it sure is. You just would not use as much. Effective sound absorption is just that. You always have a choice as to how much you use. Another advantage for the OP is that it is very light so tacking it to the ceiling is easy.
