parallel dual 8ohm parallel (net ~4), dual 16ohm, and/or series dual 4ohms (both net ~8)?

Preference in set-up (looking at possible dual woofer for a 3way).

And, thoughts on: Scanspeak M18WO-26 7" 16ohm woofers- thx

Personally, I would parallel 3x of the 16 ohm.

I agree on the 3x 16 ohm. Otherwise if it has to be two, 4 ohm requires a smaller inductor for whatever it’s worth. 

As far as the driver, if they sound anything like the PL18, which they share some visual similarities, they sound beautiful. Maybe not the detail of a modern driver but smooth and relaxed.
