If I have two subs that are in one chamber and share one port, should that port be twice the volume as recommended by the manufacturer? Or, should be the same volume as the manufacturer recommends for a single sub?

With two subs, volume is not the issue as much as the port surface area.

The port surface area must be 25% of the total surface area of the subwoofer(s). This is to prevent port noise and acheive the prope vent mach number.

Once surface area is calculated, then calculate the port volume based off of internal box volume..
