Focal subs for SPL?

I am in search of the best model of Focal subs to generate excellent sound quality while producing as much SPL as possible. Unfortunately, space is limited so the sub must perform in the smallest of enclosures. I'm expecting to allocate not much more than 2cubic feet total. Since I have never personally used a Focal sub, I am relying on experienced installers, or competitors who have experimented with various Focal subs and boxes to put their 2cents in. I'm currently leaning towards two 33kx subs in a sealed 2.12 cubic foot box tuned for 42hz. I need this to hammer and sound excellent at the same time. Yes more surface area and ported is louder, yet I can't afford additional space for box size to make it happen. I could go with 4 27v2 subs, all of them getting the same 2.12 cubic inches sealed, but tuned to 47.5hz. I'm worried the 4 subs won't play deep enough. Maybe six 21v2s tuned to 43hz? I'm expecting an spl level to remain as close to the 150db range with music while not stressing the subs.

Focal subs are not know for SPL and generally you dont use sealed box for SPL.

As well, you cannot tune a sealed box unless you are doing like a 4th order BP or a Passive Rad...

Is this even English? Grammar must not have been a priority for some in school.

Seriously though, as mentioned before Focal is not known for SPL. If you want SQL they are the way to go, but for SPL I would get some advice from other people on this site. I am sure someone could direct you in the right direction. Good luck.
