sbg Posted August 24, 2016 Report Share Posted August 24, 2016 So I just went from a FI sp4 18 in 5cuft tuned to 37 with 80 " port area, To a 18" DSS ethos in 6cuft tuned to 32 with 88" of port. And am having a problem in a few ways , first off its like 1/2 as loud. 2nd it's making a sound like it's bottoming out. Is 6 cuft to big? Power is 2 synergy audio wfo 15.1.

3vil Posted August 24, 2016 Report Share Posted August 24, 2016 What's your SSF set to? And have you done sweeps to figure out around what freq it's acting up? Link to comment Share on other sites More sharing options...
sbg Posted August 24, 2016 Author Report Share Posted August 24, 2016 What's your SSF set to? And have you done sweeps to figure out around what freq it's acting up? Ssf is set to around 20hz, seems to be be around tuning that it's bottoming out. 01 focus se 110 amp alt Big 3 sky high and stinger hpm ofc 1/0 Super start platinum AGM (starting) 2 runs of 1/0 Execution audio front to back Kenwood double DIN DDx271 A pillars- orion 4" super tweeter and 2-1" alpines.

Triticum Agricolam Posted August 24, 2016 Report Share Posted August 24, 2016 Around tuning its highly unlikely its bottoming out, since excursion it at a minimum around that frequency. However stress on the box is at its highest, so it might be something has come loose in your box somewhere, that's often what causes these kind of noises.

3vil Posted August 24, 2016 Report Share Posted August 24, 2016 You should double check the the box to make sure there isn't any loose bracing or panels. Like Triticum implied, you might have parts slapping together as the box resonates. Link to comment Share on other sites More sharing options...
