[QUOTE="LoneRanger, post: 398223, member: 540903"] port area is figured exactly how you described: Length * Width. A port that is 12" x 3" would have a surface area of 36 square inches. The depth of the port is directly proportional to the desired tuning frequency and surface area of the port. I don't know the equation off the top of my head (used to, but then I got lazy and started using CAD), but there's no need to worry your pretty little head over such things when bcae1.com gives you all those nice java calculators for free [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] [/QUOTE]
