how do u measure the length of a zigzag port...is this right?....from the opening of the port to the first wall parallel to the opening. account 3/4 for the mdf that make the turn. then measure form that same wall that u ended on and go to the next parallel wall and so on...is that correct...or should u jus measure in the middle of the port all the way around?????
