I have a eclipse 88100.4. it is 10" aluminum sub.

Here is some spec:

Vas: 2.94 Ft2.

Enclosure Volume Example:
1 Ft2(Cubic Foot) = 12" x 12" x 12" = 1728"
1.5 Ft2 box = 12" x 12" x 18" = 2592"/1728 = 1.5 Ft2

Woofer Internal Volume Table: 10" is 0.09Ft2

According to the above spec, I am confused.

What does the Vas mean? Does it mean it is the box volume supposed to be?
What does the Woofer Internal volume mean?

Does all the spec mean: 2.94 Ft2 is the box volumn supposed to be? then
2.94 = 12x12xA/1728 ->
144A = 1728x2.94 ->
A = 35.28"

so assume H=12" W=12" then the D is supposed to be 35.28"
then how the internal volume number come into play?
Did I calculate that in a proper way? If not, please advise.

Thanks in advanced.
