10" Coaxial Monitor

I am building a 10" coaxial floor monitor. I am using bass box 6 pro to help me calculate my required volume for the box, calculate port diameter and length. I am finding some strange results in the CD graph.



As you can see everything below 400HZ is above the XMAX ability of the speaker I am using.

Some info for the speaker and box parameters I am using.

Radian 5210

The box is:

VB  0.636 CU.ft
FB  79.86HZ
F3  98.9HZ

Vent:
DV 2.5in
LV 0.9391in

Is this ok? or what do you thing i need to do

I can't see the images, but I would suspect that the quoted Xmax is wrong. 0.035" is less than 1mm. It is probably a typo on the spec' sheet.
