The result is a Positive Polarity with range 10 Hz to 1 000 Hz and even with range 10 Hz to 2 000 Hz.
So the updated version of Acourate looks good!
Next time, I will however limit the LogSweep measurement for this driver as, as you said, it is not relevant to measure beyond 1 000 Hz or 2 000 Hz as there is no use to with steep XO.
