[QUOTE="squeak9798, post: 533769, member: 555320"] Also, I think you may be going about this the wrong way. Remember, in the equation it uses [B]Net[/B] internal volume, which is the volume after all displacements (port, sub, bracing, etc). So, for your new box, you [B]would not[/B] use 3cuft for the volume of the box in the equation to get port length becuase that is [I]gross[/I] and not [I]net[/I]. You really need to figure out what internal volume you want (say, 2.5cuft [B]net[/B] for example), and use that to figure out the dimensions for the port. After you have both those figured out, [B]then[/B] determine the physical dimensions of the box that will achieve that desired [I]Net[/I] box volume. [/QUOTE]
