Posted August 13, 200817 yr hi,I'm using the online port calculator at RE Audio to calculate the port dimensions. However, if i want to use two subs in a shared air space, how do i calculate the port dimensions for a shared port on the two subs?or it does not matter since the port dimensions will depend on the box volume only.

August 13, 200817 yr As long as displacements are accounted for, tuning is solely a factor of box volume, port area and port length.
