If you want people to feel the bass then a reflex design is probably best as you get the most air movement per decibel from those.      errrrr yes wtf?

without more details on those cabs its hard to say, naturally i would expect that driver to fall off quickly below 200ish hz due to its low Q/high efficiency.. 120? not likely, even with "hi tech" drivers in sp12.. ;) 160 sounds more reasonable, cut them shallower and leave a gap to the 186s, might sound better..

Data for the L12/544 is on this sheet:

The "K" in L12/554K just means the voice coil was the improved version (Kapton former).

I would expect the parameters to be very similar, though that's not guaranteed!
