Its always beneficial to know why something works. I learned something his post which I didn't learn from the others before his. Knowing why something works is infinitely more valuable than just knowing it works. Plus, it can be a great resource for other people who see it in the future.

Close, but it'* the opposite. It controls/limits how low the sub or subs can play. What kind of box are your subs in and if ported, what is it tuned to?
Why would you go against your own advice on not setting the SSF below box tuning? From what I understand, you want to set the SSF about 10Hz below tuning.....but how the hell do you do that???? So what I do is set it by ear and by eye.....I start with the filter all the way turned down to the lowest setting and play a song that I know hits lower than my tuning frequency. With the SSF turned to it'* lowest setting you'll see that your sub moves alot after the bass hits and looks uncontrolled and looks like unnecessary movement since you can't hear any output at times.......you'll see what i'm talking about if you pay attention. So I just turn the SSF up until the cone movement is controlled and tight.
In a sealed box you can turn the SSF off. The point of the SSF is to prevent over excursion of your subs in a ported box since the box itself doesn't help at all with that. In a sealed box the cone movement is much more controlled which is one of the main reasons for added power handling capabilities. So yeah, no SSF needed when your subs are in a sealed box.
