Ported for an fi 18' btl h=max of 21 in. w= max of 39in. d=25-35.. i dont know much about how big the port should be, so could someone just draw me up a sketch and give me some idea how it should look.. i would also like to have a 55 degree angle on the back of the box if it is possible if not that is ok too.. this is my first box that i am building so i really need this sketch to help me out.. thanks
