[QUOTE="Mr Cabinetry, post: 2510997, member: 571490"] To the OP, Just bag using round ports and use one larger slot port to handle the the increased air pressure that two subwoofers common chamber will need to move to reduce the chance of port noise occurring. In order for you to properly calculate the correct net volume plus subwoofer displacement for your design merely subtract the volume being displaced by the port per Inifinity's spec'd ported design. Then, use whatever design program you like to re-design the enclosure to properly calculate for a single slot port to port tuning you want, but more important, to provide enough port area so you don't get any port noise based on the amount of power you intend to push the subs with.
