ah, ok, from their cheap range
Im looking at it

its a midrange driver, and never meant to be fullrange
I notice its with just 2mm Xmax, one way
and combined with a 120hz Fs, I would say not to be used below 300-500hz
unless you use a steep active high pass filter
and/or, live with much less SPL, and power handling

btw, of personal interest, how much did you pay fore this driver ?

Yeah, the limited Xmax is a problem for all pro 6" drivers.

I paid just over 30 for it.

I'll be using a second order crossover ~300Hz, sending the low passed output through a limiter (set earlier than the main limiter), recombining the signals, and then adding an overall limiter.
This ought to keep excursion sane, allowing it to go louder for the rest of the range.

The method described above is different from how ZT did their amplifier - they just put a steep filter at 200Hz. Seems to me that more could be had in the low end, even if only at practice/rehearsal levels.
