Sealed Box Help!

[UK_VTI]

I am trying to work out the internal volume needed for the following speced subwoofer. I have tried working it out but I can not do it for the life of me... I failed math!

Can someone tell me what the best internal volume would be for a wedge shaped enclosure for a sub:

Fs (Hz): 26.4

Qts: 0.42

Qes: 0.44

Qms: 5.86

Vas (Lit.) : 55.5

Xmax (mm) : 7.5

Thanks

Judging by my calculations, a 1.1cuft box would give you a Qtc of .7 (which is generally desireable)
