Two surprising things I found that improved my imaging and staging...

Thank you for your post and link @captbeaver 
I am in a similar situation and I was wondering how far apart your speakers are now?

Correct me if I’m wrong but isn’t the goal to get a solid center soundstage, great sound,and the speakers disappear? Towing in too much gives away the location of the speaker.

Speakers big enough I guess would need to be towed. Still, once the truck leaves I think you will find they disappear just fine once they are positioned precisely equidistant and symmetrical.

😂 I have put one speak outside in the hallway, now I can’t see it !

@gp4jesus using ht for stereo and setting that up is beyond my pay grade.

In stereo systems, first reflection points at side walls and ceiling should be first place for room treatments. I'd suggest diffusion is best for all first reflection points, absorption will deaden the sound. Diffusion also works well for center of front wall.

Toe in and width between speakers work in concert, the further you space the speakers the more toe in is usually required. Get the ratio right and you'll attain the widest sound stage and still retain strong center image. As previously mentioned there are no hard and fast rules for speaker placement in any particular room and system. Multiple owners of any particular speaker will likely end up with speakers in different positions relative to side walls, front walls, toe in and spacing. The best advice I can give is to experiment, you may be amazed to find previously unthought of positioning may be optimum. Also, not too many rooms are perfectly symmetrical, mine being one that isn't, this requires different positioning for each speaker.
