It does change thing a bit, but to keep it simple.....not drastically. The only thing I would focus on with changes may be the phase differences in each setup. So if you want to stay away from having to deal with that, one port is good. Do you know the basic rules of the ports....round and square? If not, ill explain the basics to keep in mind when dealing with its area and tuning effects and resonance control.

why 2 just do one big port

a single port will generally be more efficient also.
