Hello mls-stl,
I stated in my original post once these drivers have been flexed and moved through their normal usage they become more pliable, and they drivers adjust to a state of used flexibility that the new drivers don't have.
To which you asked the question: "If a significant mechanical break-in period exists, that would indicate there is also a period at which those materials become too flexible. Those materials will continue to flex and become more pliable and over a period of time will "overshoot" the desired characteristics for optimal sound."
I think these are excellent points. I'm certainly not mechanical engineer but here's what I believe happens.
1) Speakers as a whole and their individual drivers require a break-in period to reach a state of flexibility or pliability that is optimal under what a manufacturer would describe as "normal" usage.
2) Before reaching this optimal state of flexibility or pliability the speakers and drivers can sound anywhere from horrible to ok. However, once they've finally reached the point of being broken-in they will now sound how the manufacturer/designer wanted them to sound. Whether or not that's good to you as a consumer will depend on your specific sound preferences.
3) It's certainly possible that using speakers/drivers beyond what the manufacturer would describe as "normal" usage could "if" used beyond a certain period, result in the suspensions and materials now being too flexible/pliable and hence not sounding optimal. To what degree that would effect the sound I don't know, but if done often enough I believe they wouldn't sound as good if the speakers were used as the manufacturer suggested.
I don't believe it's all that difficult to argue that speakers require a break-in period but then state they are resistant to not overshooting the target provided their continued use is as the manufacturer/designer recommends it be used.
