[QUOTE="audioholic, post: 7256127, member: 549629"] I agree with everything you said, except that formula to calculate your SSF setting. The SSF is there to keep your sub from over excurting once the signal deviates below enclosure tuning. When you go below encl tuning, the sub unloads, and cone excursion increases rapidly. So as you can imagine, how quickly the system unloading will lead to over excursion relies on three criteria mainly: subwoofer's excursion potential (xmech in this case), power delivered to the sub, and enclosure size. In other words, there is no generic calculation to figure your SSF setting, every system is different. Whoever told you there is, doesn't understand the physics of the sub unloading below tuning. The closest you'll get to an equation that is still a valid answer would be, you can generally go a half octave below enclosure tuning as your starting point to get you in the ballpark, and then adjust the SSF according to your specific system and needs.
