Voice coil material - Double insulated aluminum(AWSV)

The function of the insulating layer is similar to the process of aluminum oxide, but its specific hardness is not as hard as that of aluminum oxide, and its rigidity is slightly worse than that of aluminum oxide. One layer of insulation and one layer of glue. The main function is to reduce the risk of short circuits in the placement of voice coils.

Long term temperature resistance of 180 degrees
