Does anyone know of a company that sells the metel speaker cover material that is used in automotive applications.
Basically is a sheet of metel (Aluminium ??) with tiny holes all through it that cover the speaker in doors and dashes etc.
It is called perforated steel, it comes in various gauges, materials, and with different style holes. Hope this helps.
