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.
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
\(K=\frac {1}{D}×(\frac {2.35625×10^4×D^2×N}{V×F^2}-L)\)
Known data: diameter of vent; number of ports; volume of box; tuning frequency; vent length, what is the end correction factor?
Input data: diameter of vent--2 cm; number of ports--1; volume of box:--3 liters; tuning frequency--2 Hz; vent length:--1cm, click "Calculate" to display the result.
Output: end correction factor:3926.6.
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.
