Port Length Calculator

Formula

To calculate the Port Length:

$L = \frac{(2.356 \times 10^4 \times D^2 \times N)}{(V \times F^2)} - (k \times D)$

Where:

A port length is defined as the proper length of the vent of a subwoofer.

Let's assume the following values:

Step 1: Use the formula:

$L = \frac{(2.356 \times 10^4 \times 10^2 \times 2)}{(50 \times 30^2)} - (0.732 \times 10) = 31.41$

The port length (L) is 31.41 cm.
