The second design is 7 cubes at 37hz (actually closer to 36.75hz).What are you actually looking for?<img src="http://i18.tinypic.com/4xz5pi8" alt="" class="fr-fic fr-dii fr-draggable " style="" />That's your port length and the shaded area is the area seen by the sub after port displacement. Multiply that area number by 21.75 and you have your net volume before sub displacement. After sub displacement, it's 7 cubes almost exactly. The length is about 26.25" after end correction.</blockquote>
