"Efficiency Bandwidth Product (EBP)
EBP = Fs / Qes
50 or less = best used in a sealed enclosure.
50 - 90 = flexible enclosure options.
90 or greater = best used in ported enclosure.
Qts < 0.30 - ported
Qts = 0.30 - 0.50, use ported or sealed.
Qts > 0.50 sealed"

Thank Glasswolf for this:

Use the calculator at the bottom of this link, enter all the data and it will tell you what kind of enclosure is best for that sub.
