EX Series II 10" sub displacement

Just got a pair of ex series II 10" sub's... I don't see a spec for the displacement of the driver itself in the book.

My question is...

Is there a way to calc this from the spec.'s that are given in the manual, or,
am I missing it somehow, or,
does some one just happen to know it?

Thanks in advance...

The displacemnet for these woofers is .042 cubic feet.
The recommended enclosures have included this in the net internal volume of the box. The sealed volume is .65 cubic feet per woofer and the vented volume is 1.0 cubic feet per woofer.
