727Designs Posted July 14, 2011 Report Share Posted July 14, 2011 whats the formula to calculate this?? some people use different formulas, but this is a commonly used one Thanks guys its much appreciated so I should be fine with my SSF at 35hz?? You need to figure in sub displacement to get the exact final tuning, then stay 4-5hz below that for the SSF. sub displacements would barely change the tuning, and given that his are shallow mounts it might change a couple tenths at most, if that even I missed that post. My bad. Quote -Zach-2010 Toyota TundraFull Hybrid Audio SQ 7" BDS on 37's 2000 Ford Expedition 160+ dB Green Turd -SOLD- Link to comment Share on other sites More sharing options...
