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.
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
\(F=√[\frac {2.35625×10^4×D^2×N}{V×(L+K×D)}]\)
Known data: diameter of vent; number of ports; volume of box; vent length; end correction factor, what is the tuning frequency?
Input data: diameter of vent--5 cm; number of ports--3; volume of box: --8 liters; vent length:--1cm; end correction factor--2, click "Calculate" to display the result.
Output: tuning frequency: 141.71 Hz.
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.
