I don't think I've posted this here before but a few people might find it helpful. It's a rough estimation as some will have more cone area and less surround area and vice versa.

Use the colors to determine how many of one size will yield the same cone area of that number of another size.

an 8" circle doesn't have the area of 100...unless I'm doing something wrong

3.14xR^2
radius is 4...4^2 is 16, 16x3.14 is 50.24?

I made a sticky of this before, but formatted differently. Maybe you could post this in that sticky as another reference? I think this is equally helpful.

Wow I totally messed that up. I made it years ago, I squared at the wrong step. Thanks for catching that

What thread's it in? I'll fix the error and throw it in there.

Fixed version. Of course this is a really rough estimate, as it's just the size of the sub itself and not just the exposed cone measurement. Still helps to get some idea.
