jarrius Posted February 4, 2014 Report Share Posted February 4, 2014 Take the sealed specs for that sub and some say double them or triple them for the ported side. So kicker says 2-3cubes for sealed that means 4-9 cubed ported if you want. But the best way to figure for a band pass box(from what I am told) if to build one and test. If you don't like it build another with different specs and test it. Then repeate if you don't like it 2012 Chevy sonic1xSQ HDC3 12 D2RF R1200d 140 square foot of Q-Mat(soon to be installed) 140.2Db sealed on the dash with TL 142 DB sealed on the dash with another meter (was dead on with the TL at a show i was at) 141 on music. strangeduck,on 02 Jan 2014 - 01:39 AM, said: when my car spins out i just put the car in neutral, turn in the direction i want to go and pucker my asshole Link to comment Share on other sites More sharing options...

RooTxBeeR Posted February 4, 2014 Report Share Posted February 4, 2014 I've ran several L7 S15 : they love huge box, sealed, or ported. Don't tune too low for 4th order ported : 35 Hz is good for an L7. I can't tell you for 4th order bandpass. I've never tried that. How do you give out advice on how to design a 4th order, then right after say how you've never encountered one. Please do not listen to this man. 45Hz? a milli a milli lmao my point exactly OP. The REAL way to tune the port of a 4th order is to tune the port to the peak frequency of the sealed section. That can found with a few tools, on being the SMD IM-SG and also the Dayton audio DATS. That is the best and, in my opinion, to the only way you should tune a 4th.
