[QUOTE="hispls, post: 8855645, member: 614752"] You're not trying to figure out the mass of air in your 3" port or whatever, you're trying to figure out the mass of air that you would need in an 18" round port for your desired tuning since an 18" port tunes by vibrating a column of air of that mass. Start over by entering 18" round port into your box software and determining the port length required to get down to your desired tuning. Your mass is going to be closer to a pound assuming your box volume is 6 to 7 cubes or thereabouts. [/QUOTE]
