Being 20+dB below reference is pretty good considering it was designed primarily for sub-bass and not to function like a woofer. I would not be afraid to run that unit to 100Hz.
Do we even know what harmonic that curve is?
We shall continue to play the game of "X" motor topology with really short coil rated at 3 times as much power as any normal person would rate it at..and then wonder why 80% of them break...but by god it has low inductance and it'l play out to 300Hz flat (which is still VERY narrow bandwidth all things considered)..minus that little dip in response at the say sub 30Hz range because it runs out of excursion because the coil is short...
When will people learn that you need to focus on a solid 3 way setup...you shouldn't have to worry about inductance with anything that is honestly 'sq' related...as a sub never ever EVER plays anything above 50Hz in a SQ car that is worth its salt when being judged...
Inductance in and of itself should be more closely examined in a mid-woofer/midrange/tweet alignment...which is where "X" topology would be more at home imo.
