then goto page 29, gives exact size needed for 4.5 cubic foot box tuned to 33hz. gives all board length and widths needed. should help alot.

that box would be to big , I figured out a box without vent, 12"high, 29"wide, 29"deep, would be 4.565, but thats without vent, need help with vent

yea you can change the deminensons, you can even bend the port if you need to,
32" long
20" wide
16" deep
32x20x16=10240/1728=5.925
.42 for port displacement=5.50+276in sq for sub displacement=5.36
now after accomedating for thickness of your wood you will be under a lil bit, or you can just add .75 to all the deminesons...
now for the port im not 100% sure how to calculate it, the site shows .42 cubit foot displacement. if that is only thing that needs to be constant here this wont be a problem,
if above is true then you can take 15.25w x 3h x 16l=.42361
sounds good to me but there may be more to it than that, wait for one of the other guys with experience on this area. i have not build a ported box before so i cant help with the porting area here. sorry
