Calculate Length of Vent or Port
L = Length of Vent or Port D = Diameter of Vent N = Number of Ports V = Volume of Box F = Tuning Frequency K = End Correction Factor
Calculate Volume of Box
V = Volume of Box D = Diameter of Vent N = Number of Ports F = Tuning Frequency L = Length of Vent or Port K = End Correction Factor
Calculate Tuning Frequency
F = Tuning Frequency D = Diameter of Vent N = Number of Ports V = Volume of Box L = Length of Vent or Port K = End Correction Factor
Calculate End Correction Factor
K = End Correction Factor D = Diameter of Vent N = Number of Ports L = Length of Vent or Port F = Tuning Frequency V = Volume of Box
