It seems everybody did. The actual calculation for cone area on a sub would be

Ca = pi x r x s where s is the distance from the surround to the center of the cone. And thats because you have a concave, conic base on a cone (sub) and that's why the chart numbers are higher than one would think.

I was wondering. Would 4 15" sub have more cone area than 8 10" sub? Not sure.

yes

4x15=706

8x10=628

Even thou the 10" sub have more Xmax and proper build enclosures with solid electrical it not be loud as 4 15" sub? I know that more cone area would be loud but i think it depend on electrical, install, music type, vehicle, and most importantly the enclosures types. What do you think?

If you take xmax muliplied by cone area, that will give you the volume displacement. If you're dealing with sealed enclosures, this is important to consider. this is not the end all be all solution though. Look at DD subs, being loud without huge xmax specs. ported is a different beast altogether
