HRMMM? I'm clueless about speakers. I posted about getting replacement speakers/drivers/whatchamacallits a while back. These things seem massive, 504 grams for a 3" speaker?

according to this diagram  .  .  .



.  .  .  it's the surrounds that are blown out/deteriorated, that's the same as foam?

Do the cones remain stationary with the foam removed?

These speakers were reputed to be excellent back in the day. Was that rep warranted or an Apple myth?
