but that's assuming it sustained 2kW for any appreciable amount of time, which it didn't. even the 2-3 minute demos on music weren't anything near full amp capability. i've seen these same subs do more than that for hours daily.
that gets to my original question, how many have seen a coil unwind and what were the circumstances? how many have had a brand new sub fail within hours and why was it (besides pure SPL destruction purposes)?
obviously, to get the coils to unwind they need to be hot enough for the glue to let loose. the amps never went into protect and the coils aren't shorted. they weren't ran long enough to overheat from extended use (only pushed a few minutes at a time). if they coils were mis-matched, one coil would heat up more than the other. that is the only concrete evidence we have right now, mismatched coil DCR.
