Replacement diaphragm for the genuine WE 555 driver.
Here is a replacement diaphragm that I developed. Since the Western Electric 555 driver was used around 1930, there are very few replacement diaphragms left to date. As a result of the blind test, we could not tell the difference sound between the genuine diaphragm and the replacement. Customers who need a diaphragm will send the driver to me and send it back after replacement.
