GueroZ28 Posted December 11, 2013 Report Share Posted December 11, 2013 Im building my 1st box for 2 12s.. they need 1.65 cu ft (recommended amount) i want the port in the center . Can someone tell me how i can find out how big the port should be? Thanks also. Right way in finding out the air space and how to tune if that matters?

shanesauce Posted December 11, 2013 Report Share Posted December 11, 2013 Dude you have made like 3 different threads asking the same thing... Give me the max dimensions you have to work with and will give you all your specs and a cut list. - 2012 Mustang 3.7 Manual - Audio under construction Link to comment Share on other sites More sharing options...
Krakin Posted December 11, 2013 Report Share Posted December 11, 2013 Good luck with your port that will have less distortion, less to no compression, and less turbulence, and better driver cooling.

CleanSierra Posted December 11, 2013 Report Share Posted December 11, 2013 He never said which 12s yet. It may not require that much port depending on the subs and tuning preference Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...

But you know, who wants a good sounding box.. So you want a port with more volume than the box? Doesn't matter the size of the box, you still need X port area, no matter Y net volume. When designing a driver enclosure, with space limitations, don't pick drivers that will require more gross volume than you have to work with.
