SSF off because you have a sealed box...however if you want to really prevent the sub from overexcursion put it on. try it at each setting and see how you like it. id set the LPF at 80hz wit ha 24db per octave slope.

yep...you blow it mechanically. depending the the design of the sub it happens slightly different to each driver. overall, just remember going past xmax for extended periods of time causes it to blow mechanically. the SSF's main purpose is to prevent overexcursion in a ported box below tuning when the driver unloads. for sealed boxes it is not necessary but I've had people prefer the sound of the SSF being on which is odd but o well.
