A real 'room & body' shaking experience with explosions in movies generally comes from large boxes & lots of power.
In the original 'first post' about Alpine drivers, no power-handling specs. are quoted, or what power amount you have.
Also, the Qts specs. of all 3 drivers are above .5 > That is really too high to start with for want you want.
For slightly compact Subwoofers ( yes - left & right ) I wouldn't pick a driver with Qts above .39
What you really need is drivers with LOW Qts, low fs and high efficiency > But these come at a cost $$$.
You can find lower efficiency drivers with low Qts, high power & BIG Xmax, but then you need the power to SHAKE THINGS.
It would probably be good for the 'thread' for you to elaborate on your POWER-DRIVE-SITUATION.
PS.
As mentioned, the use of corner placement can be greatly useful.
Also mentioned was that 'software simulations' are not always realistic.

Correct, max box eff. charts.BUT note these equations DO NOT APPLY TO LOW BASS AT ALL.

SO TRUE ...The sensitivity spec is a MIDRANGE value which doesn't necessarily have anything to do with the bass sensitivity.
Have a look at the frequency response VS sensitivity rating of this CHEAP woofer.
