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.

The size of the baffle in which the driver is mounted is a big part of this too.  There have been plenty of A'gon threads arguing about wide baffles vs. narrow baffles.
Smaller drivers with similar bass extension have lover sensitivity.
Lover sensitivity drivers have more thermal distortion and compression. 
You can do nothing against laws of physic.
Small drivers and speakers are good for marketing people:
1. Better WAF
2. Cheaper to built !!!
3. Increase sales of expensive super powerful transistor amplifiers.

IMHO the fashion and huge popularity of low sensitive speakers with small drivers is the one of the biggest delusions in audio.
I don’t talk about really small rooms. For small room small driver speakers are OK.
