fecupe2001 Posted June 19, 2012 Report Share Posted June 19, 2012 subs forward port back, 1.25 cubic feet per sub or maybe 1.5 cubic feet depending on your power, common chamber with 2 6" aeros facing back, if you have a termlab would be much easier, you might even work better with 3 6" aeros but you need a sensor to test that out...

Goblenator Posted June 19, 2012 Author Report Share Posted June 19, 2012 why so small of a box? Link to comment Share on other sites More sharing options...
Redcorn245 Posted June 19, 2012 Report Share Posted June 19, 2012 Yea i have been looking for an spl box for my single hd 12. I called ab and they told me the box needed to be 2.5 cubic ft per sub. But i never asked about aeroports bc. Was just making a simple slot port box. But mine is 2.5 tuned 34Hz and Im pushing it with 1500 rms this thing pounds hard and gets low as shit lol. Its def louder then my two 15" Memphis audio cast m3s and even hits lower Link to comment Share on other sites More sharing options...
8ight Posted June 19, 2012 Report Share Posted June 19, 2012 2.0-2.5 cubes net/driver, drivers on top, aeros on sides. I'm gonna hate Link to comment Share on other sites More sharing options...
fecupe2001 Posted June 19, 2012 Report Share Posted June 19, 2012 Because it´s an spl box and crx loves small boxes since they peak so high, like i said, depends on the amount of power you have also, subs forward/port back is they way to go with that pair of 12´s I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.

Ddub847 Posted June 19, 2012 Report Share Posted June 19, 2012 umm isnt it subs up port back Link to comment Share on other sites More sharing options...
fecupe2001 Posted June 19, 2012 Report Share Posted June 19, 2012 subs up/port back works very nice on a CRX, that´s why you can use subs forward and up with port back when you are using 4 subs, but when you have only a pair of 12´s, subs forward/port up it´s the best combo for a rex, at least the 2gen , don´t know about the 1gen or even wich crx op uses....
