Which one is the best.
carstereo, RE, and 12volt all yeild the exact same results. 3 cubes net 48" area yeild 31.5" length for a regular port. Is there another calc thats better?
carstereo has a feature to account for a slot port. Yields 29.5 length for the above box parameters.
Is the calc on carstereo accurate when accounting for a slot port? Is this why the RE calc is said to be way off, since it only allows you to design a slot port but they dont shorten the port accordingly.
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)
Please correct me if im wrong.
Now for a kerned port how do you determine the length? IIRC its half the length of the flared section.
Again please correct me if in wrong.
