Hello.
First post here. I have searched the net for a reliable helmholtz calculator
but for some strange reason the ones I have found do come up with two
different results. Example for all calculations where:
Box volume:1000L
Port diameter: 30cm
Port length:10cm
Results where either 25hz or 46hz. If someone could point out what the
answer should be that would be most helpful.
Here is the list of the ones I have found so far.
I guess it’s copy/paste if you want to try them out.
