To get the widest soundstage, even on the outside of the speakers, which can vary from speaker to speaker.
Start with the the tweeters directly at each ear. Watch for the center image and the imaging on either side of center. Then keep towing both out in increments till you start to loose the imaging either side of the center. Then you know you’ve gone too far and toe them back in slightly.
This is your best imaging that you’ll get between the speakers, and if you get imaging on the outside that’s a plus.
The more toe out you have, the better chance of having imagining on the outside of the speakers, but you can loose the the imaging on either side of center as I explained above.
And imaging depth comes from having nothing between the speakers as far back as possible.
