Alot to ask - 8-10" 'full range' high sensitivity type woofer for sealed box?

Didn't put this on full range forum as I'd want to cross around 2khz - the only drivers I can find that are a close match are from Visaton and ESS. Wd like to end up with a true 92+ dB sensitivity and f3 of around 45hz if possible. Large box size is fine
 
the closest i get is the Faital 10RS350, that is 91dB sensitive but fit all other requirements (not fullrange but high enough in flat response). But like said, it's hitting hoffman law's border limits... If you can crossover lower more is possible.
 
60L could get you there. I don't have a driver suggestion though.

Sensitivity is one thing, though I refer to efficiency on the below chart.
