rookie023 Posted February 19, 2009 Author Report Share Posted February 19, 2009 (edited) can any one tell me if that area that im talking about is going to mess up the sound of this box. if i should change the placement of ne thing? is it even necessary for the port to be that tall? could it be a shorter port?

HELP! Changing the height and width of the port almost always changes tuning, but not always. Say if your running a 40" by 5" port, with a 10" port depth, 200 square inches of port. and switch to a new port. Say 20" by 10" port, with a 10" port depth. your tuning will still be the same because you are still having 200 square inches of port. Now if you went with a port that is 35" by 10" with a port depth of 10 inches it will be a change in tuning because you now have 350 square inches of port. To figure out square inches of port you multiply port height by port width. IE: 20 times 10 = 200 -OR- 40 times 5 = 200. You should try to go for 12-16 square inches of port per cubic foot of space after displacement for 18" subs. 25 cubed box should range from 300-400 square inches of port.
