Does your sub have a phase control?
I've been painting and moving around furniture as the result. leaving it displaced until I've findished up for a little while now. The offset arrangement of my furniture affects my sound stage. Albeit, not so much the imaging.
If you have a phase control on your sub, you've lots more freedom in where you can set it, aside from openings, and furniture constraints. I currently have my sub set in front of my left speaker facing across both speakers firing from one side wall to the other, left to right, about 3 feet and six inches off the side wall. I've done this same thing with a sub sans phase sw, but it had to be much closer to the plane of the speakers. Also placement in my room of the sub sans phase sw would change the depth of the sound stage as well... further behind the speakers, got me more depth, closer to their plane of operation eventually being forward of them, decreased it.
If you run the sub in L+R (stereo).. you've at least a 180 phase conttrol... just reverse the inputs to see if that helps any. Ya never know sometimes until you try things for yourself. G
Good luck.
