2007TBSS Posted February 24, 2012 Report Share Posted February 24, 2012 I wanna do a smaller ported side fire box so I have some cargo area left. I have some 4" Aeroports that I wanna run. Does the port area per Square foot matter so much when not doing slotted ports? This seems to be the right size and tuned right. Is there anything I am missing or does this look good?

Joe X Posted February 24, 2012 Report Share Posted February 24, 2012 (edited) Minimum recommended PA/Vb is 9 for aero ports, best way to know is using WinISD free software, Port Mach below 0.05 is best. Without telling which subs can't say. Edited February 24, 2012 by Joe X Quote Link to comment Share on other sites More sharing options...
carshateme Posted February 24, 2012 Report Share Posted February 24, 2012 (edited) G'damn Joe, you're all over the place..wtf. lol Port area is a little too small, like he stated above...recommendations is 9 for minimum area.

2007TBSS Posted February 24, 2012 Author Report Share Posted February 24, 2012 Dammit. I always have this trouble with ported boxes. Whenever I get the port area right, my tune is at like 50hz unless the port is like 3 feet long. The subs RE SEX 12's.

will77530 Posted February 24, 2012 Report Share Posted February 24, 2012 (edited) 4 4" aero 21 in length...... tuned to about 36 you can also try shrinking your box down a bit Edited February 24, 2012 by will77530 Quote Link to comment Share on other sites More sharing options...
2007TBSS Posted February 24, 2012 Author Report Share Posted February 24, 2012 4 4" aero 21 in length...... tuned to about 36 you can also try shrinking your box down a bit The RE site recommends 2^3ft per sub. Is that semi negotiable based on port tuning? I was actually incorrect on the original post, I can only go 20" high instead of 25".

will77530 Posted February 24, 2012 Report Share Posted February 24, 2012 (edited) im not too familiar wit there subs honestly what kind of power are you putting to it? rms more or less? you dont have room unless your pushing more than rms.....your at 3.59 before displacement Edited February 24, 2012 by will77530 Quote Link to comment Share on other sites More sharing options...
2007TBSS Posted February 24, 2012 Author Report Share Posted February 24, 2012 I'll probably end up with a HiFonics 5 channel for saving room sake. It says it'll do 1ohm mono bu with my 2ohm DVC's I can only run it 2 or .5. So unless those amps are ballsyer than I think they are, it'll be 750 x 1.

will77530 Posted February 24, 2012 Report Share Posted February 24, 2012 if you could make the box bigger it would sound better and be louder but with the dimensions you listed.....20x12.5x35 with three 4" ports that are 16" long it will bring you to about 37 hz good luck bro take pics Quote Link to comment Share on other sites More sharing options...
2007TBSS Posted February 24, 2012 Author Report Share Posted February 24, 2012 Can I stray from the 2^3ft per sub rule for the sake of tuning? Or does that number need to stay pretty close?
