Illuminati (33rd Degree)

I'd call it six one way and a half dozen the other. Both the bass-reflex and the transmission line have internal dimensions that encourage standing waves at specific frequencies in the midrange. If these frequencies are allowed to enter the chamber, they will tend to energize standing wave modes. So stuffing and/or crossover electronics that attenuate the midrange inside the cabinet are a pretty important detail for either type of enclosure.
