[QUOTE="hispls, post: 7569533, member: 614752"] We already established that compliance will continue to soften for the entire life of the driver. I still maintain that the change after the first few minutes is negligible and probably inaudible (can you hear one or two tenths of a db, or the difference of 1.5 to 2hz in tuning?) If you really do have that magic ear you will have to continue tweaking through the whole life of the woofer as the suspension most definitely keep softening. Again, if it makes you feel better, do it. The whole mythology surrounding the idea and all these theories about how to "properly" do it seem as much superstitious ritual as my raincoat method. We confirmed that TSPs change over the life of a speaker as suspension softens. We did NOT prove that this "breaking in" is needed to prevent premature failure of a woofer, and we certainly did not prove that a difference of 10% in TSPs is even audible or much more than you would get from one driver to the next through normal manufacturing tolerances. Take your favorite modeling software and throw in a typical car audio woofer. Move Q and Vas up 10% and Fs down 10% and compare the two curves. I bet very very few people could tell the difference.
