Still curious about the non-linearity issue for ported subs, though.
I'm not sure about the non-linearity issue you are speaking of. The data-bass tests were run using the same testing parameters, but even then there are microphone tolerances, distance tolerances, weather condition tolerances (heat, humidity, cold, wind) that can cause slight variances, and that doesn't include when the microphone was last calibrated (calibration is another tolerance) or perhaps another microphone was used. When one talks about 1 or 2 dB output difference, to me they may be virtually identical in performance because of all the tolerance build up involved. Now, when one is talking 5 or 6 dB, that is significant. But once that sub is place into a home, all that goes out the window. The tests are there for basic comparison purposes, and won't necessarily predict what the outcome will be inside a home environment. And even if a subwoofer's performance was perfectly flat through the frequency range during testing, I can pretty much guarantee you it won't be once it is inside your home.
I think we get so caught up with numbers, charts and graphs, and getting that last ounce of performance that we forget to kick back and enjoy ourselves.
