double check my math sub enclosure

Measure twice cut once. Can some one double check my enclosure.. The box is for 3 SWR-1043D Subs. Reccomended enclosure volume by the manufacture is .60 Gross cubic feet. given space requirements I got a net internal dimension of 10x10x10.5 (per Chamber) W X H X D Given the material is 3/4 MDF it would give me a cut list of. Front and back 33 x 11.5 Sides and dividers 10 x 10.5 Top and bottom 31.5 x 10.5

I did not check your math, but the only thing that stands out is, if your endcaps and dividers are the same size, the top and front should be the same dimension, either 33 or 31.5

I can see clearly now.. Thanks for the help

Glad to help.
