Yes, it's my PI-12 woofer, an OEM version of the LAB12 machined to fit the cooling plug. For the three Pi subs, you could use either driver just as well.
I'm using a pair of those Selectronic 50W Class-A FET amps. Plate amps work great too, and are probably more convenient 'cause they bolt on the back.
I use my little passive preamp - that remote control circuit I made for the DIY and kit amp crowd - and split off the outputs to the amp for the mains and to the crossover for the subs.
