If Jeff says that graphene covers the cones, then I would take that to be the truth. I have found Jeff to be an honest and forthright guy, and I believe his representations without hesitation.
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.

Also, kind of interesting that Seas makes a lot of woofers for Magico,SEAS does not make any drivers for Magico, I know you consider yourself an expert, but one look at SEAS offering will make you realize that their drivers are built on a completely different platform (smaller voice coil, dustcap or bullet plugs vs Magico’s solid cone, etc. I am not even sure they have any Nd motors). SEAS drivers are ancient artifacts in comparison to Magico drivers. Seas now added Graphene on top of their cones (Magico did that 4 yeras ago), so JA can offer it as well. JA never claimed it is his own drivers, BTW... |
If Jeff says that graphene covers the cones, then I would take that to be the truth. I have found Jeff to be an honest and forthright guy, and I believe his representations without hesitation. Except as noted above, he's selling the Pulsar as using an exotic crossover when it really seems to be quite a common design. |
@erik_squires ... Well, we certainly disagree on the purported simplicity of the xover and Jeff’s integrity. Here’s a link to the initial patent application for the xover by Modafferi ...https://patents.justia.com/patent/7085389 It doesn’t appear to me to be a simple second order xover, and I believe that Jeff has improved it over time. JA’s measurements in SP are not always the final explanation. |
