Radian 2218 NEO? 21mm x-max

[mr. doom]

Xmax = ((winding depth - magnetic gap depth)/2 + (magnetic gap depth)/3

TC sounds PRO5100 Xmax = ((76,2 - 38,1)/2 + 38,1/3 =
= 19,05 mm + 12,70 mm = 31,75 mm

Good enough for Barbra Streisand

I wonder if that 21.3 xmax is actually the linear p-p. The spec sheet doesn't show voice coil and gap heights.
Edit: I skipped a page, obviously

All manufactures measure differently and then smooth them out.
