AMI CUSTOMS Posted August 7, 2012 Report Share Posted August 7, 2012 Run torres again with just 46.5 x 3.5 for the port and see what length it comes up with, aim for 9 cubes with tuning at 38. I was guessing port length needed to be close to 18 for 38 hz tuning. But you will have to adjust other perimeters to get it right. If you are tapped out on room then I would tune higher with more port area vs lower with less port area.

Cutdeluxes1 what sort of bracing are you doing that will take 1.5 cubic feet?? also if you are doing 1.5" wood all around why you have it set to 0.75??

Cutdeluxes1 what sort of bracing are you doing that will take 1.5 cubic feet?? also if you are doing 1.5" wood all around why you have it set to 0.75?? That number for the bracing is what torres all ready had in it. I used .75 to get the outer dimensions of the box, and them Im going to re-inforce the outside of it with .75 wood. So my air space and stuff wont change, just have to keep it in mind for the port length. atleast that is what i figured. Quote Link to comment Share on other sites More sharing options...
