New Joseph Audio Pulsar Graphene 2

Just wanted to update my prior thread where this topic may have gotten lost.  As many of you may know by now, Joseph Audio has come out with the new Pulsar Graphene 2. This new iteration of the venerable Pulsars has a graphene coated magnesium midrange-woofer cone, and the drive motor, suspension system, etc., have been revamped. From what I have been told, the upgrade is pretty significant ... the sound is fuller and has greater ease, yet is very resolved. Jeff Joseph advises that an upgrade path will be available for existing owners of the Pulsars, too. Also, note that the price quoted in the Soundstage piece was in Canadian dollars ... Jeff informs me that the price in USD is $8,999 per pair. I am eager to hear the new Pulsars.

Does anybody know if there is a Joseph Audio dealer in South Florida? Thanks.

I was recently informed by a well known speaker designer that the reason graphene and other new coatings are being used is to
keep the cones themselves from self destructing. So now you will be
paying more so the product you buy lasts longer. Okay some logic there but let's not fall for the 'Improved SQ' claims.

@gadios I wonder if graphene and non-graphene specs are identical then?

@gadios — Given what others who have actually heard and/or owned both versions have said, I’d say you have been misinformed.  BTW, I — and I’m sure others here — would love to know which speaker designer told you this stuff.  And, as far as I know, Seas drivers haven’t been known to “self destruct” over time so that reasoning sounds totally absurd. Maybe you should listen for yourself rather than just accepting as truth what someone else says, especially someone who probably has not done an A/B comparison between the two versions.

There was some discussion about the graphene coating and IIRC seas also emphasized it's use for preventing, I think, Oxydization especially in certain climates.  So I think there is truth to what gadios wrote.
However, the new Graphene Seas drivers were more than the coating - other aspects of the driver were re-designed, which is one reason the crossovers had to be re-designed/tweaked for their use. 

All together, with the sight changes in the drivers and Jeff Joseph tweaking the crossovers, it makes sense the new Joseph Graphene speakers would have evolved their sound somewhat.
My local JA dealer finally got the graphene Perspectives in so I'll probably hear them this week or next week.
