People have asked me what I do to come up with my calculations for box volumes and port areas and lengths. Well, here are two pics of both the excel worksheet(edited without formulas purposely), and a response example of 2 15s anechoically calculated using it.
It is not really meant for anyone to understand what is going on here. But jsut giving you an idea of what it takes me to come up with two perceptually basic figures of volume and port compared to any online calculator, or anything else anyone uses.
The purpose here is to show those who asked me, "what do you use to model your boxes?", one of the worksheets......and I mean one of them.
Questions about this process or about the worksheet will unfortunately not be answered in detail. But, any other audio questions that may arise are welcome!
