[QUOTE="mendon mafia, post: 6544514, member: 584590"] Ok so its settled the calcs are all the same. Now help me out here: IIRC for a slot you can extend the effective length of the vent half the width of the port longer that the actual length, on both sides. IE for a 4" wide port you would add 4" in length (2" on for each opening) or is it just for the opening on the inside of the box for just 2" added. Now for a kerned port how do you determine the length? IIRC its half the length of the flared section but this may be for flared i forget. [/QUOTE]
