onyx1silverado Posted June 25, 2011 Author Report Share Posted June 25, 2011 So when you guys say port area, you just mean the width by height not width by height by length. And is the port calculator on the 12 volt fairly accurate (I have a mac so i cant use torres box calc)?

RAM_Designs Posted June 26, 2011 Report Share Posted June 26, 2011 (edited) id do 37"W x 13"D x 18"H. box comes out to 3.1 cubes net after displacements. port should be 11.5"H x 4"W x 25.25"L tuning comes out to 36hz. It'd actually be a little smaller and tuned a little higher since you didn't account for sub displacement...like 2.82ft^3 with a tuning just under 38hz.

onyx1silverado Posted June 26, 2011 Author Report Share Posted June 26, 2011 See I put 2.8 for the box size on the port calculator because dc's website says 1.25 per sub and I think it is .14 for the woofer displacement. So do I need to make the box a little bigger to account for the space the port takes up or should I leave it at 2.8 Quote Pioneer AVH-P4200DVD Rockford Fosgate T5001 bd-cp 2 DC level 2 12's Focal Access Components in the front Focal Access Coax in the rear doors Rockford Fosgate Punch Boosted Rail 4 channel rms 4x75 XS Power D3400 under the hood Knuconceptz Ultra Fleks Power & Ground Link to comment Share on other sites More sharing options...
onyx1silverado Posted June 26, 2011 Author Report Share Posted June 26, 2011 I appreciate your patience and help. I can do sealed boxes all day but when it comes to ported I feel like ripping my hair out.
