Hmmm... Just thought of something: If the efficiency disparity was too much, you'd be getting a lot more sound from one set of speakers vs. the other pair... So, the efficiency of each pair should be close, no?...
Also, there was something else I discovered as an audio salesman way back... And that was that the woofers on one pair of live speakers would affect the movement of other woofers on speakers that were near, but not energized... I mean, the un-energized pair woofers would move out of phase with the live pair... In other words, they'd sorta act like passive woofers, which some speaker designers use in their enclosures...
So there's a lot to consider here... I've often wondered what effect all those speakers in Steve's soundroom(s) have when one pair is cranked up, but the others are just sitting there... It simply has to affect the overall sound, no?... I mean, if you do a test, you can see the dead woofers moving sympathetically with the live ones... I've seen this myself...
Then there's the issue of hooking up a sub or aux. bass speaker directly to the same terminals on the amp... That would bear on the same issue at hand here, no?...
Anyway, thoughts welcome here... (m.)
