For as long as I've been in car audio (not long), sub break-in has been a topic I haven't had a clear answer in. My question is, what T/S parameters will change once the woofer has had adequate break-in time, that is if any change (this would make me think its a myth). I've heard that the Fs of the driver lowers because the spider(s) loosen up, and if that is true would it also affect Qms of the driver? The reason I ask this question is regarding the Maw 15, would the break-in of this woofer affect which enclosure to stick it in? I have been modeling this woofer in WinISD and the woofer looks optimal with a 32hz tuning instead of a 30hz tuning you guys suggest(this is with 3 cubes). Sorry for this very long, and probably useless question.

Thank you,

the T/S specs given by the manufacturer are post-break-in

Yup. Just as Acid said, drivers are exercised before parameters are measured. So what is posted gives you the closest numbers to "real world" as you can get.

Best,
