[QUOTE="Ed Lester, post: 4663790, member: 587479"] 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. [/QUOTE]
