Difference between 1 or 2 subs in one chamber?

[blue fury 3]

I have 2 Rockford Fosgate rfr3110's and Im planning on building a ported box for them both but I want to know the difference between separating the 2 subs to one sub per chamber (2 ft^3) with 1 square port each OR having both subs in the same chamber (4^ft3) with 2 same sized ports.

Basically, I have the size and dimensions of the box ready to draw up, but should I have a divider between the 2 subs in the box?
