WOLFRAM FTW
yeah thats true not all songs have bass below 40 really., i had a issue with factory dual orion xtr ported box 18 yrs ago (before i knew about tuning) it was like $589 box at our shop i said i wanta try that today owner said fine swapped out my memphis came back next day he sold my memphis subs so i had orions couple weeks on a memphis 500d with 25hz ss filter 250rms per sub both the cones ripped like they'd been cut with a knife.. i wonder if ss filter coulda been set at 33hz would it have saved them is all., but box was probably tuned to like 50 hz so guess not lol..SS filter at 24hz is fine and will be sufficient for those tuned above 31hz. Some sub/box combos will naturally have a steep roll off and don't even need ssf. 99% of songs out there don't go below the mid to low 30s.
