May I have the statistics for the QC process? For some reason I cannot find anything in AKG's website.
By the way, here is some data on speaker drivers breaking in over time (no shifting pads here):
Again this test also does not conclude anything IMO. Only 6 samples available, and I don't get it why he used 30% tolerence for the test to begin with, which is a massively wide critical region for such hypothesis test. Plus what distribution is being used here? Parameters?
Statistical tests only work if they are carried out properly, with enough data and external factors being taken into account carefully. Otherwise they might even bring more misjudgement into the debate.
Edit: if this test does not mean to be a statistical test, discard my comment above regarding the quality of the test.
