RW-12:

2 RW-12's:

(+6dB max acoustic output due to having 2 speakers)
RSW-12
119dB @ 30Hz 1/8 space, 1 meter
Actually, it's +3 dB due to having 2 speakers and doubled the power, not 6 dB.
So it's 116 dB.

Technicality speaking this is partially correct. But that is not accounting for constructive interference, which also means you can have deconstructive interference and actually have LESS bass than before! This is unlikely but I would say you will have somewhere in-between +3 to +6 dB gain depending on your phase shift. Its important to have an SPL meter to get this perfect.
IMO, I would say go with dual RW-12's. You'll probably get more headroom and definitely a lot more cabinet volume out of the two powered drivers, but the output it will be very close between the dual rws vs the single rsw. The other notable advantage with the RW-12 is the placement features. As front firing front ported drivers, you can put them back up against any wall or even build flush into a wall. That might be pretty cool later down the road.
