Consumer Electronics

Today’s consumers demand exceptional sound quality from their speakers. One of the main components involved in the delivery of crisp, clear sound is the speaker dome. It is important that the dome be made of a clean ultra-thin metallic foil to allow efficient transfer of the electrical signal into sound waves over a range of frequencies. Also, in order to prevent failures in the speaker’s operation, the foils must have a defect-free surface finish.



Gauges: 0.007″ (0.178mm) to 0.000085″ (0.002159mm)
Widths: 19.0″ (419.1mm) to 0.035″ (0.9mm)
