Don't forget the displacement of the speaker it's self..Not sure about port volume, don't know if you have to account for all the air space in the port as 'not space' or if it's just the actaul material of the tube/port... Though, I thought I read someplace that the air volume of the port makes the woofer think the box is smaller?? which would mean subtract the air volume.. but like I said, I'm not sure there..EDIT: From the above equation, the port volume subtracts from the box.. so if you had 1 ft^3 of port volume, your box would only be 2.4 ^3... make sense? (but your port isn't that big.. you just have to take it into account)..</blockquote>
