You do realize how thin the graphene layer that we are talking about is, right? We are talking about extremely low mass here in comparison to ultra dense and quite heavy graphite in a pencil... the mass difference between the two is beyond disproportionate in this case. I wouldn't expect to measure any level of conductive-ness of graphene to be that near to pencil lead with a simple civilian-grade multimeter. I suspect it would take an ultra-sensitive and ultra-expensive laboratory grade instrument to detect such difference in conductivity... maybe I am way off in my thinking and experience. Also, graphene of this grade and application is not terribly expensive in comparison to other widely used diaphragm materials such as beryllium or titanium... even some ceramics and newer bio materials are costlier than graphene but still are heavily used without hesitation and at quite reasonable manufacturing costs. So I be really surprised that they be lying about it being a graphene diaphragm but I do accept there is always that small possibility that they are. LOL!I measured the resistance of the driver diaphragm and it is not conductive with my multimeter, a resistance greater than 100M ohm. A carbon pencil lead was conductive. The diaphragm is more stiff than the 150 ohm blue glue driver. For the sound, all i can tell is that it clearly need burning, the first hours were harsh, bass were lacking.
To others: What say you? I think it could be quite an interesting topic for discussion as many new materials and grades are appearing.
