with respect to the member from new york, i'd place the mid-bass punch in the 50-150hz region.
it requires uncompressed sound at "live" spl, which is up around 120db for the peaks.
NO ROOM RESONANCES. once past that...
high sensitivity drivers can get there more quickly than low sensitivity drivers, but if you put enough low sensitivity drivers and amps behind them, you will get there too.
there are tradeoffs though. most home theater folks like very deep extension and the high sensitivity drivers typically fall on their butts for that, so it is a tradeoff.
mid-bass performance is a complex interaction of motor strength (low qe), impedance location (which determines how much current is actually drawn through the motor), and raw sensitivity at the target frequency given the design (sealed, ported, horn), and distortion control (suspension/bl/induction linearity) etc.
