Calculation of the minimum port vent diameter at the exit of the subwoofer
Calculation of minimum port vent diameter, maximum air volume, tuning frequency
Select the appropriate unit and enter a value and click on "Calculate". The result will be displayed.
D = Minimum Port Vent Diameter
V = Maximum Air Volume
F = Tuning Frequency
N = Number of Ports
\(D=\frac {2030×（\frac {V^2}{F}）^{\frac{1}{4}}}{√N}\)
Known data: maximum air volume; tuning frequency; number of ports, what is the minimum port vent diameter?
Input data: maximum air volume: 10 cubic meters; tuning frequency: 5 Hz; number of ports: 5
Output: minimum port vent diameter: 1919.9 cm
The unit of maximum air volume, tuning frequency and minimum port vent diameter can be selected. Click on the check head to select the corresponding unit.
