Subwoofer vent length calculation
Calculation of vent length, volume of box, tuning frequency, and end correction factor
Select the appropriate unit and enter a value and click on "Calculate". The result will be displayed.
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
\(V=\frac {2.35625×10^4×D^2×N}{F^2×(L+K×D)}\)
Known data: diameter of vent; number of ports; tuning frequency; vent length; end correction factor, what is the volume of box?
Input data: diameter of vent--1 cm; number of ports--5; tuning frequency--3 Hz; vent length:--8cm; end correction factor--6, click "Calculate" to display the result.
Output: volume of box: 935.02 liters.
The unit of diameter of vent, box volume, tuning frequency and vent length can be selected. Click on the selected head to select the corresponding unit.
