The Eminence 3015LF is pretty efficient, but does not go super low. The Eminence Lab 12 is less sensitive on paper since sensitivity is measured mid band, but a pair will put out a lot more below 40 HZ.
If you are willing to give up 14 cubic feet of real estate, horn loading (technically still sealed) can increase efficiency tremendously over a simple sealed box, but may require time alignment.
If you have to stick with the sealed box idea, think in terms of multiple cones, each doubling of cone area gives another 3 dB efficiency, multiple low Xmax drivers can be far more efficient than a single high Xmax driver.
