subs and power is what moves the air...

Different port sizes and shapes will yield different port air velocities. The volume of air moved maybe the same. Speed can change though. In most cases a lower air velocity yields a higher SPL.

Also, location of the port can make a difference depending on how well the airflows inside the enclosure.

Sometimes you can have the same subs, amp, box, and port. just reposition the box and airflow will change.
