So given that, the question should be, are mfgs listing the avg, max, or min impedance on the cabinet spec sticker?


Since there is no standard, the manufacturers can list whatever
impedance they want; within the range of impedances that the speaker
has in its frequency range. For example, some speakers rated at 4
ohms dip below 2 ohms at certain frequencies.
