Okay, for the 10 x 57 x 19 i came out with 6.267361 when i multiplied then all and divided by 1728.
For the box i know will fit...well, it seems as if it will.... its 37 x 22 x 14... multiply that and divide by 1728 and i get 6.5949074 ... which is of course the outside measurements and its 3/4" wood so give or take a little. This box would fit... from what i can see... and i would have the sub mounted in the top. Would it matter if i had it right in the middle of the box or off to a side? Also, with those dimensions whats the real volume? that equation im guessing is a typo or im retarded?
