New Dual Magnum Box Tuning..

[n0ftInc 10+ year member]

So, tonight I ripped apart the old box and started to design the new one. The old one was a little too big and bulky for me, so for this one, I would like to downsize it a little bit. I worked out and figured on the dimentions of 13.5 x 16.5 x 36. Working with 3/4 MDF I am looking at 4.641ft^3 as external and 3.594ft^3 internal. This is before the driver (2 * .07 ..?) and port displacement ( ..?). I want to have the port along the 36" side, I am just having difficulty finding the correct length. I am aiming for 33ish hz. If anyone could quickly run some figures and shoot out an answer, it would be most appreciated. Thanks! //content.invisioncic.com/y282845/emoticons/bowdown.gif.b85b23b82970bd22fb6b549c3392f016.gif

This is what I am aiming for.. The port is only going to be 34.5" long after you take out the .75" MDF..
