Those measurements look a little strange to me. Re(series) should be about four times Re(parallel), and such is not the case. Also, there should not be so much change in Qes. My guess is that some error was made in the parallel-coil measurements.
Anyway, I think the series data is good, and a little 2A3 amp will want to see the coils in series.
The key to getting good bass out of this woofer is BOUNDARY REINFORCEMENT. Left to its own devices, it is very weak below 100 Hz. If you can put 'em in room corners, I would try maybe 4 cubic feet tuned to 40 to 45 Hz as a starting point. If no corners are available, tune to 50-55 Hz and have the speaker down near the floor, angled back a bit. If you want the speakers up near ear level, go with 2.5 cubic feet tuned to 80 Hz, and add a subwoofer for 80 Hz on down.
My advice is free and worth every penny.

Me being a dealer makes you leery?? It gets worse... I'm a manufacturer too.
