2x2x12inch or 2x15inch subwoofers

I am deciding between either a Rythmik G22, E22, or E15HP2.

I will buy 2 of each.  Would 2 12inch drivers deliver more room pressureization or 1 15inch driver?  Salk recommends 1 15 inch over 2 12inch woofers.  I have 2 REL S510s in the front of the room connected by both High Level and .1 and the speakers higher up would be in the back of the room.

Room is 2200 cubic feet, and has full accoustic treatments.

I just want everyone's opinion on whether a sub with 2 12" drivers will output more low end extension than 1 15" driver
Both specs on their website say 14Hz lowest bass response. Smaller drivers are generally faster.

Read myth #9 -  Myth: smaller subwoofers are faster than larger ones. Big subwoofers sound slow and inarticulate.

What is the longest dimension of the room (think in 3D)?  That will let you calculate the lowest bass note the room will give you.

15 feet...761/15=50ish hz.  That is my room mode that is the loudest and it is +15db, or should I say before my room treatments.  That room mode is closer to +3db.  I use Room Correction to correct the rest.  It goes much deeper than 50hz in this room.

@golfnutz I must be reading too much REL propaganda! I would suggest that all things being equal, the smaller cone is faster but in reality, probably not. I stand corrected.
