[QUOTE="Immacomputer, post: 2726325, member: 570419"] The port = a column of air mass. End correction = air mass that is a part of the port. Net volume = volume of air the sub sees. Port air volume = volume of air the sub does not see. Therefore: Net volume does NOT include the end correction because the end correction is part of the port. Also, the end correction does not vary with the strock of the sub. It moves with the column of air in the port. Read those links and you will see everything I just typed is true. If you cannot understand the logic behind this, you might be borderline retarded. [/QUOTE]
