Usually, I just estimate a cylinder from the magnet to the spider and use that. Where the equation is Pi * D^2 * h * 0.25. Where D is the diameter of the magnet and h is the distance from one end of the magnet to the spider. That’s just what I use. I don’t believe box volume is sensitive enough to warrant any closer approximation of the driver volume.
