Does anybody know what the black markings on the metal acoustic dampeners are for?
(please ignore the zoom in of the driver, this was the best photo I could find)
The dampener of the HD650 are metallic though, so it can't be a support material
What would make you think that a metallic fabric could not and would not have supports? Actually, I would be interested in finding out exactly what material the new silver mesh is - I have only seen in person the original plastic mesh that is in my HD 600.
In reality, the black "markings" are molded plastic beams that are in fact the supporting structure for both the driver and the fabric. Look at any picture of the other side of the driver and you will see - like right here.
