Yes.
There were two stages to my room treatment. First, I strove to kill direct reflections behind the speakers. While I tried only treating the spectral points (i.e. the mirror reflection method), I found the more acoustic foam I used on the backing wall the better. Imaging increased with each successive step, finally leading to my lining the entire back wall with 4" pyramid foam (8 2'x2' tiles). Second, I increased difussion surfaces on the rear wall (wall facing the speakers). I placed several large pots with leaved plants along the back wall, each placed upon modest wooden tables. I also changed my curtains to a bamboo slotted type. But the most significan improvement came when I placed an array of semi-spheres along the back wall to diffuse the primary wave; it brought the ablility of my system to resolve micro-dynamics to a whole new level. I cannot say enough about that move.
I also have corner reflecters, but to be quite candid, they add little (to nothing) to increased system performance. I have also attempted to kill primary reflections from the side wall, in addition to the ceiling, however in both cases, the improvement was not worth the asthetic impact.
So nothing radical, save working on the two primary aspects of room treatment:
1) Kill the back wall reflections
2) Diffuse the facing wall reflections
Makes all the difference in the world.
Best,
