So,,,we are not sure whether this is a genuine or replica.

I bought these 604b pair from a dealer for $3800 and he insists this is genuine. One woofer cone paper ruptured big time and repaired.
I decided to buy this pair thinking if the diaphragms are genuine it is worth. But when thing like this, I am thinking to return.

As I have a 604RWB, maybe later I can make it a pair.

Hmm...what should I do?
