Also a sealed sub can still produce the same bass extension given the proper driver size and a HUGE amount of wattage behind it. A ported design is just easier to run and design to achieve lower bass extension or high output, also a ported design allows the user to tweak the port opening, ala my PB13, for more output or lower extension.
