pk222 Posted December 2, 2010 Report Share Posted December 2, 2010 I'm almost done building a 2.58 cube box for my 2 12 in ssa d cons. The last thing I'm stuck on is the ports. I have it set up for dual 4 in aero ports. I cant find a calculator that says how long they need to be each. I found one on carstereo and it came up with 19.78 but didn't say if that was each or divided between them. Does anyone know? I'll try to post up a build log when I'm done.

fecupe2001 Posted December 2, 2010 Report Share Posted December 2, 2010 Torres calculator works awesome, you can find it on a sticky post in here, but, if the calculator said it needs to be 19.78" then it´s EACH tube, that´s one small box actually, i wouldn´t try to tune it very low, i would get something like 18" each tube so you end up around 2.3 cubic feet and 38 hz tuning.

pk222 Posted December 3, 2010 Author Report Share Posted December 3, 2010 I know the box is small but thats as big as I can go in my 97 convertable mustang. I already have to partially build it in the trunk. Do you think those subs would sound good ported at 38 hz? Their recommended for a little bigger box than I can provide but said to tune between 30-34 hz. And I'm thinking of flaring the ports which says to add another inch onto the port. Would it be worth flaring it? I'm not worried about numbers I doubt I'll even ever run it on a meter I just don't want port noise. Quote Link to comment Share on other sites More sharing options...
fecupe2001 Posted December 3, 2010 Report Share Posted December 3, 2010 Well, for around 2.3 cubic feet 2 4" ports it´s more than enough IMO, i don´t think you´ll have ANY port noise with that, i would use PVC tubes and start playing the system, if it has port noise then you can always flare the pvc or buy original aeroports if you want to spend the money on them, about the tuning, yes i do think it should sound very nice, with that little box even tuning it at 25 hz i don´t think you´ll be able to play the lows strong, that´s why i´m suggesting you to tune it around 38 hz, but i might be wrong, so who knows? there´s always different opinions on this forum hehe.

fecupe2001 Posted December 3, 2010 Report Share Posted December 3, 2010 You are welcome hommie, one again, i would try different port lenghts until you find the one that sounds better to your ear, pvc 4" is cheap as hell!!!!

pk222 Posted December 4, 2010 Author Report Share Posted December 4, 2010 I already have a 5 ft piece of abs. I don't see why thatd be any different than pvc Quote Link to comment Share on other sites More sharing options...
Robert8252 Posted December 4, 2010 Report Share Posted December 4, 2010 Small boxes "can" play lows just to put that out there. Lol. But try what works and go from there. If it has to let the port stick out a little Quote 2013 F150 Crew Cab Old Build Log Feedback 2013 F150 Equipment - Some Awesome Stereo Sound Making Stuff Link to comment Share on other sites More sharing options...
pk222 Posted December 4, 2010 Author Report Share Posted December 4, 2010 Its going to have to. The box is only 14 in deep. I'll just cut it long and keep cutting it down until it sounds best and if I go to far then I'll grab some more abs and make it where it sounded best.
