I have been offered two 2440 drivers as it seems with 2441 diaphragms. But on the pictures I received (taken from the side, so not looking in the throat) one throat is black and the other is silver. As you know from a picture it is difficult to judge, but does anyone know if there were silver colored throats? Or does silver mean that the throat has been taken out and in fact only one of the two drivers still has its throat?
