New Joseph Audio Pulsar Graphene 2

markalarsen,

Yes I know.  I just find it odd that IF the updates for the Perspectives go well beyond merely a new coating on the drivers, that that information isn't included in the announcement of the new Pulsar 2.

I mean, audiophiles always want as much as they can get for their money in upgrades, which is why audio companies are typically at pains to depict upgrades with as much significance as possible.  So "new woofers with entire new motor system" would sound much more exciting and appealing than just "woofers with a new coating."  Which is why I"d expect such details to be part of an upgrade announcement.

Bunch of info here on what I presume to be the same or similar new SEAS graphene drivers:

Good find Prof, reading the specs on their site, the big difference I see is power handling. Long term power handling has more than doubled.

This is by no means a simple graphene coating though, as the article points out, significant changes to the voice coil and suspension have occurred, while the overall frequency response is barely touched. This makes me wonder if the graphene coating is anything more than a paint job? Their white paper mentions corrosion protection as one of the first benefits, a good thing:

Also, linear travel remains the same 14mm in both, so the maximum limits are going to be similar.


From what I read here, no one should be worried their original Pulsars will be suddenly and severely upset by the new version.


OTOH, if you are Prof and looking for a deal, wait for A’goners and dealers to put the original versions on sale. :)

PS - I do see enough changes to the impedance and overall sensitivity that I expect this will require nearly completely new crossovers, and slightly lower efficiencies.

So much great things about these speakers; part of me wants to hear them while the other part knows ill never have the kind of money to spend so why bother.

i feel like prices keep rising which keeps otherwise loyal people out of the game entirely.
