now that won't fit where you want the box to go usually so you have to retain the same internal volume but play around with the height x width x depth.

mulitpy 1(cubic feet) x 1728 = 1728 cubic inches
devide 1728 by your height (lets use 16") = 108
devide 108 by your width (lets use 14") = 7.7 (or 7 3/4 inches)

so now you have your dementions 16" x 14" x 7,3/4"

To double check when your done: 16x14x7.75 = 1736 (cubic inches), 1736 / 1728 = 1.004 (cubic feet) ...close enough

you can use any shape box as long as the speaker will fit into it and it has the internal volume specified by the the speaker manufaturer or by someone who knows how to design a speaker box.
