Bigger drivers = bigger soundstage


Ideally, I don’t like to be aware of a speakers location in a room and like having sound being well centered for tv/movie listening.  I have two listening rooms and the one with larger drivers (older) fills room so much better vs better speakers (newer) with smaller drivers.  Room acoustics favor larger driver speakers.  
Seems dispersion is better.  The larger driver speakers do not image as well but very enjoyable to listen too. 
So now I am upgrading the smaller driver speakers to better and larger driver speakers and it follows a larger speaker cabinet also occurs.

all speakers herein are from same manuf.

Hmmm... you don't say. My current speakers are larger cabinets and larger drivers and do image slightly better than the previous somewhat smaller ones. So I guess you're right. But the ones before that were even smaller and had the best most 3D imaging of anything I ever heard. So I guess you're wrong.

But the first ones had dipole tweeters. So just maybe there's more going on than physical size? Food for thought.
 Room acoustics favor larger driver speakers.  


That's a loaded statement, what specifically are you saying? 
"...The larger driver speakers do not image as well..."

Your post obfuscates at minimum.  We have no clue unless you tell what you are running.
