I want to find out how wide the port needs to be for specific frequencies. I suck with math. I have the volume, and the frequency, there will be no neck. Can someone break down the step of how to figure out the port. Also, what units are necessary? I want to just use cm, will that be fine if I just use cm for all the measurements?

The equation that I am using is here

You can plug in your values in the fields and the unknown will be calculated.
The acceptable units are given for each quantity.

I would like to caluclate it manually though. I dont want to use an online calculator. Already knew those existed.

So you want to solve the equation for A? And what do you mean by "there will be no neck"?
