    What Bill said. Also, 200Hz is a bit high to cross to subs, unless the subs are co-located with the satellites.

    That's not true. In blind testing EQ'd for identical response and trimmed for identical output one cannot tell if a sub is sealed or ported. The main advantage to sealed is that in a maximally flat alignment the enclosure can be much smaller than ported, at the expense of how low it will go. That can be compensated for by EQ and power if the driver has sufficient Pe and Xmax, but by and large where sealed is most appropriate is in smaller rooms where low frequency response is aided by cabin gain. By the same token in a small room a ported sub can have too much low end due to cabin gain. In short, small rooms and sealed subs are a good match, large rooms and ported subs are a good match. Small rooms and ported subs, large rooms and sealed subs, not so much.
