There's probably a place in your room where the bass will be fall into line. Exploit the room.
I've had similar problems. A rough formula for me was the 1/5th rule. If you start there, you can make adjustments over time and start to lock the speaker location.
With regard to speaker position, consider this to be the vertical centerline of the tweeter at the front baffle. Divide the room in 5ths. Place speakers 1/5th from backwall and side walls.
Also eliminate any hard and glossy elements in the room. If you have framed pictures with glazing move those to another room. If you have hardwood floors, thick Persian rugs with requisite thick felt under pad really helps. A large rug under the speakers really helps.
Work on first reflections first...this is what creates the smear that kills focus and sharpness of the sonic image.
