cnate777 Posted March 28, 2009 Author Report Share Posted March 28, 2009 is there an equation to getting the tuning Quote Rockford Fosgate Sundown Audio DC Power Inc XS Autometer Pioneer Link to comment Share on other sites More sharing options...
cnate777 Posted March 28, 2009 Author Report Share Posted March 28, 2009 ok I think I am going to do a 10 x 10 x 10 port which gives me a tuning of 35.38 hz what does everyone think also that gives me 11.5 cubes after bracing and 45's. Does anyone think that will have port noise with that size port? Quote Rockford Fosgate Sundown Audio DC Power Inc XS Autometer Pioneer Link to comment Share on other sites More sharing options...
