That's not the point he's making.thats not totaly true...
take a sub new in the box and test it with a wt3 and see what the specs are then put 20 or so hours of play time and then re test it. the specs will not be the same. most subs will play lower after a few hours of run time then they will bnitb.
He said play it at low volume for a period of time vs. playing lots of power at the beginning will yield the SAME results. The suspension will soften regardless of how you go about it.
