[QUOTE="wagz, post: 647281, member: 549081"] wait what am i missing here?? yes the port stays the same surface area throughout with 15"x3", the port is 27.25" long, and no the port does not have 2 exits, the sides are only for the air to move and are not part of the port, the end of the port is marked by the green lines. the 2 sides combined have more surface area than the port hole itself so i figured it shouldent be a problem ( (1.463 x 10^7 x (45/pi)) / ((27hz^2)(5x12x12x12)) ) - 1.463 x the square root of (45/pi) = 27.75" .... my tuning is around 27hz sorry for the insult [URL="http://trmafia.net/wagz/pics/aa%20new%20sub%20system%20progress/j%20braced%20and%20caulked%20800600%20labeld.JPG"]http://trmafia.net/wagz/pics/aa%20new%20sub%20system%20progress/j%20braced%20and%20caulked%20800600%20labeld.JPG[/URL] [/QUOTE]
