    question on building a sub box for Eclipse

    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.
