[QUOTE="southstylestang, post: 3272825, member: 550431"] Im gonna be building a box for my Fi 12 BTL b/c my last one didnt fit. It wasnt tall enough and i wasnt thinking about the front being angled too much for the magnet to fit. Plus it was a smaller box. So I designed a new box. im going to put the sub facing the front with triple baffles. I just need help designing the port for this one. Not sure wether to use a round port or a slot port. I wanna tune it to 32 hz. Could somebody help me figure the deminsions for a port. The box according to rockfordfosgates boxwizard the box is going to be 3.3 cu ft before the port and sub displacement. Heres a pic RF calculator i used to figure the area.
