Port area

[Alexander Persson]

Hi

I'm new to the forums and I could not find any posts alike the one I am making right now.

I am going to build a enclosure for my new subwoofers.

They are 15 inch subwoofers and they are pretty beefy. 25kg each. (I have 2)

I am thinking about making the box 240L in volume.
Tuning it to about 40-45 Hz.

The issue i'm having is that I don't know how many 6" ports I am going to use.

Thinking about going with 3-4.

So the issue is that I don't know what would be the optimal port area.


Any kind of help is appriciated.
