Well i figured id do some calculations box would be 30"x12"x28" (width by height by depth) which comes out to 5.13 cubes - port would have to be 12" tall by 6.25" wide to stick with the 16" length to hit the 40hz tuning, i was just wondering if i could make it 12" tall by 4" wide which would come out to 25" long - was just wondering if this different port size - since it isnt 16" long would still be at 40hz - help me!   how do i figure out my tuning?</p></blockquote><p></p>
