App description
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.
F = Tuning Frequency
V = Maximum Air Volume
D = Minimum Port Vent Diameter
N = Number of Ports
\(F=\frac {V^2}{(\frac {D×√N}{2030})^4}\)
Usage example
Known data: maximum air volume; minimum port vent diameter; number of ports, what is the tuning frequency?
Input data: maximum air volume: 10 cubic meters; minimum port vent diameter: 5 cm; number of ports: 2
Output: tuning frequency: 6.7927e+11 Hz
Note
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.
