The mesh is just pressed against a ball. The center is undistorded, there is 
also about no distortion going up-down and sideway. The diagonals are distorted.
Then, a metal ring is placed around and welded in place. The exess parts are 
then cut away. End result: an hemisphere. Two are fitted together, the back one 
having a hole cut into it to fit the body of the mycrophone.
