You seem to be saying that because a speaker has lower sensitivity, that means that it will play louder.
That makes absolutely no sense at all.
The way to determine how loud a speaker will play is to calculate it from its sensitivity and maximum power rating.
For example, if a speaker is rated for 90 db/watt, and its maximum power-handling rating is 100 watts, then it will put out 110 db SPL maximum. If it can handle 200 watts, it will give a 113 db SPL at 200 W.
If a speaker is rated for 85 db/watt (LOW sensitivity), and it is rated for 100 watts, it will put out 105 db SPL maximum. If it is rated to handle 200 watts, it will give 108 db SPL maximum at 200 W. 400W would give 111 db SPL, IF the speaker can handle that much power.
Lower sensitivity means less sound per watt.
To get a 125 db SPL from a speaker with a low (85 db per watt) sensitivity) you would need 10,000 watts of power (and the speaker would have to be designed to handle it...seen any like that lately?).
It is ridiculous to claim that you are getting 125 db SPL from low-efficiency speakers; that isn't possible.
The QSC speakers are theoretically rated to put out 131 db SPL, but that doesn't mean you have anywhere near the power it would take to do it; IF they have HIGH sensitivity (95 db/watt), you MIGHT be able to get a 121 dba SPL , which would take 400 watts. (131 db would take 4000 watts).

My room is 19x13' sealed.
The question is if anyone has ever gone back to low sensitivity speakers in their theater after hearing high sensitivity? and why?
Im going to go out on a limb and say that the only people with low sensitivity speakers in their theater have never heard high sensitivity speakers or require high WAF. or maybe their room is 12x12
