1loudsuv, you can go on being ignorant all you like. Let me explain to you a little bit the variables involved with infra/sub sonic reproduction. The transfer function of the room dominates the frequency response, so frequency response is a very hard variable to control between listening rooms, but should stay pretty consistent from driver to driver. The power response of the sub can be considered negligible since the radiating surface of the driver and the speaker baffle are much less than the wavelengths being reproduced, so homogeneous reproduction (excluding room resonances) can be expected. The transient behavior of the driver can also be considered negligible since the cycles we're dealing are much longer than the overhang caused by the driver, and the room resonances dominate the decay behavior of the low frequencies. This leaves us with one big factor...harmonic distortion, and since our hearing sensitivity sharply declines as the frequency goes lower, the harmonic may actually exceed the fundamental in amplitude. The distortion profile of subs dominates the subjective differences. The design (open baffle, dipole, sealed, cardiod, bass reflex, etc) dominate the frequency response and room resonance profile.
Power compression is also a serious consideration, but at the moment I don't feel educated enough in the area to go into great detail. What I can tell you though, is that a high efficiency design with low power requirements will get louder and sound better than a low efficiency high power requirement driver as far as dynamics are considered. Just because a driver can handle X amount of watts, does not mean it will remain linear with SPL as the power is increased. As a driver is expected to handle more power, the theoretical 3dB gain caused by doubling of power is reduced by power compression. It will not get as loud as it should.
I've backed up my claims with physics and objective data...all you've brought to the discussion is "I don't care, it doesn't matter".
