Manufacturing info about mic grills

FAQ #2006 Updated January 11, 2013


I realize that this is a very unusual query, but I’m curious nonetheless:

How is the grille of the Beta 58A made: i.e. how is the mesh attached to the grill-rings? I presume it is welded to the rings by means of a resistance welding or similar process. I see that apparently not all of the wires have formed a successful bond with the middle and base rings, where they meet. Is this normal, and what percentage of successful mesh-wire to ring welds would be considered acceptable during manufacturing? Have you ever come across a grill failure (i.e. coming apart) due to impact to a microphone, e.g. falling?

You’re response would be greatly appreciated!
