The speaker is installed in Vb1 playing into chamber Vb2 where the port(s) are installed.

In this example the voice coils are connecten in parallel to 2 ohms.

CALCULATE YOUR ENCLOSURE

Box volumes:

When caculating the volume of an enclosure you simply multiply the width (W) x heigth (H) x depth (D).

Use measures in dm and you will get the answer in liters.

A trapezoid box is calulated as below:

Vol=width (W) x heigth (H) x upper depth (UD) + lower depth (LD) 2

RUNNING-IN PERIOD

Allow the speaker to play for at least 15-20 hours. After this time the performance is correct.
