[QUOTE="cpcg32, post: 1895360, member: 561171"] I am using WinISD to design a ported box. I want two ports, one on each side of the box so it's symetrical. My dimensions of the port are going to be 13.5"(.343m)x4"(.102m). When I tell it I want 2 vents, it says the length needs to be 18.197ft. That is abusurdley wrong. If I say one port, it tells me 8.831ft. That seems a little more reasonable but still kinda long. It is going to be a 1.88ft^3 box tuned to 26hz. Can anyone help figure out what the length of each port needs to be? Should I raise the tuning frequency? [/QUOTE]
