Swisher2015 Posted February 8, 2016 Report Share Posted February 8, 2016 Im about to start building a better box for my 2 sa12s but I'm not sure on how to figure out how much port area I need to tune it, I'm wanting to tune around 32-35 hz, my dimensions I'm going off of now is 40w-15h-14d (od), subs up port out the side. Any help calculating port would be appreciated. Wood is 3/4 thickness, I've searched but can't find a box with dimensions close to mine.

Joe X Posted February 8, 2016 Report Share Posted February 8, 2016 So here is a suggestion, power: to subs rated, amp subsonic filter to 28Hz, minimum port clearance 4 1/2", figure is just an assembly guide: Link to comment Share on other sites More sharing options...
