i have one of the original DB 12's am i am trying to figure out how close i can have it mounted to the back of the box where the vent is on the magnet. i understand that this has something to do with cooling the sub? i have heard as close as half and inch and as far as 3-4 inches. what is correct for this sub. i don't have much space with the design i have chosen to go with so any help would be appreciate. thanks.
