I am compiling a list of woofers that I am considering from the top dogs but part of my decision is dependent on how much space their boxes take up. I don't need exact dims only how how many cubes. Is there a simple calc that I can setup in a spread sheet? I mean I would of course plug in the key specs (whatever those are - vas, xmax, whatever??). Can you guys help me with the actual calc and the bits of info needed and I can make the sheet and the formulas. And I need this for both sealed and ported. Is this possible?
