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.

Graphene is a stiffener and a very good one, super lightweight and super-stiff, that’s what everybody wants for a transducer. Hel-loo! And that’s why graphene is very effective in tennis racquets (Djokovic’s racquet of choice for the last six years) and why graphene would be an excellent material for use in tonearms, platters, CD trays, CDs, isolation stand top plates, etc. What’s next, Graphene wall paint? Bring it on!
So, we have Graphene cables, Graphene contact enhancer, and Graphene coating for tweeters. I imagine Graphene would have other audio applications (where stiffness is a virtue) - cartridge, stylus, tonearm, CD (label side), isolation stand top plate, speaker cabinet. 
As graphene is one, two, three maybe four molecules thick I kind of doubt it will have much of a damping effect.

“Ideally I’d love to see graphene damp the ringing and allow for higher use of the mid-woofer.”

>>>>>That’s weird. Graphene is a damper? I would have assumed graphene was a stiffener.
