Sub box dimensions

Systems

I have a signle MM2104 (I think that's it. 10" 4 ohm MoMo). I want to build the exact box that Polk reccomends (.66 cu. ft. sealed). In the box plans area all it really gives you is outside dimensions, and I was wondering if anyone can help me figure out what sizes I need to cut each board (top, bottom, front, back, left, right) when using 3/4" MDF to get the right dimensions? I know that if I figure it out I'll wind up making it too small and the sub won't fit. They say these dimensions:

Overall External Dimensions
Width 15" (38.10cm)
Height 13" (33.02cm)
Depth 9-141/250" (24.29cm)

Thanks for any help.

Sorry about that the dimensions where a little off the depth was looking weird so we check it and we noticed an error it should be 9-9/16" instead of the weird fraction.
Here is the link to the subbox plan.

For the CORRECTED size.

15x13x9.5 with .75" thick =0.719

14x13x9.5 with .75" thick=0.666
which is closer to what you need
