room size question.

@rlb61 

if you have read all my replies....i have GIK panels, i have the bass traps in the corner, i have the acoustical panels behind the listening chair and i have the stand up diffusors..

speakers are( i forget now as  i have moved them so many times,) but from the back wall to the rear of the speaker they are out at least 3 ft, maybe more....and 29" from the side walls.

if i go wo wide with them, then it sounds just like 2 speakers playing and i lose center imagining.         i have the triangle from speakers to listening chair.

@bshaw Sorry, I haven’t read the entire thread. However, when measuring speakers from the back wall, the measurement should be to the front baffle, not the back of the speaker. Similarly, side wall measurements should be to the front baffle. Also, it looks like you may need to move the speakers closer together since you’re not getting any soundstaging with them wide apart ... if you move them closer in small increments with no toe-in, there should come a point where they will snap into focus and you’ll achieve a nice soundstage.

absorption panel behind your listening position. 

From my own experience, if one wants bigger soundstage in a small(ish) room, diffusers should be used on the back wall (and the front wall, but to a lesser extent), not absorbers. Even side walls, a combination absorber / diffusers may work better

@rlb61  , this was kind of where I was going with suggesting OP start with a small equilateral triangle with about 4' spacing & then moving wider in increments to see if he could catch a good spot.  But I am also thinking that having his equipment between his speakers will be problematic. 

if I go to a concert, I don’t hear a soundstage, most of the time I just try not to go deaf with my sensitive ears,

@grislybutter  ,  I thought you made good suggestion and points; however I would think that if you went to a small mostly acoustic performance that you probably would hear some sort of sound stage.
