Crandis16 Posted August 25, 2012 Report Share Posted August 25, 2012 another good box calc is on bcae1.com it gives very similar results to torres. trying this calc, but im confused on the square port ratio part...? there is a range that you want to aim for... I think it's 14-17 in^2 / ft^3 for port... or 12 for aeroport because of efficiency.Each sub reacts differently to the box so keep that in mind Quote My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL Link to comment Share on other sites More sharing options...
