My first ported box, and wanna make sure this goes right.

I am planning on on 3Cubes, slot ported, tuned @ 28hZ....
i didn't know if my LxWxH where in the right place.. is my diagram correct?

and the
H: 8"
w: 2"
L: 14"

would tune me to 28hZ right??

this is box could possible be for a Shiva if that matters... I know more xmax you are supposed to keep vent more "square".... is the 4:1 ratio square enoug.....
