※There is a slight dent in the center cap on one side, so it is inexpensive. Dayton tweeter. It is a model with exactly the same structure as a high-class tweeter, using a 1 inch titanium diaphragm and cooling the aluminum voice coil with ferrofluid. If you are a self-made person, please give it a try. (TAMURA Eiji)
