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.

Thank you for the mini review and comparison. I have never heard the Perspective so I cannot make a comparison but the Perspective2 I heard had zero flaws for me in Jeff’s room/setup at the show. 
Maybe being too close to the wall caused that issue for you. 
I really think that if I can buy the Perspective2s one day, I would be set for life in the speaker department.

"..the Thiels were as usual a somewhat richer, thicker sound, with very dense, round imaging, very organic and relaxing, but also dynamic. The main thing missing in the Thiels vs the Perspectives is the exquisite refinement of timbre up in to the higher frequencies. They miss that gorgeous sparkle and aliveness of the Perspectives."


I wonder if that difference might be, at least partially, down to the use of aluminium drivers in the 2.7s against the magnesium drivers of the Perspectives.

In any case I have also noticed that exquisite timbre in the higher frequencies, (perhaps 5-8kHz?) that most metal drivers seem to bring, along with an almost crystal clear leading edge speed which can make other drivers appear slightly blurred in comparison. It’s not night and day, but it’s there.

Of course, as you found in your response to the differences in comparitive bass reproduction, all loudspeakers seem to present a balancing act of various strengths and unfortunately unavoidable compromises.

Even so, it’s still those strengths we all ultimately strive for.

I've had to unlearn some intuitions along the way, or at least modify them.

I agree there does seem to often be a certain character of cleanliness and clarity with metal driver speakers.  And this can come with something of an acidic or metallic aftertaste on the tone.  I also had the belief that metal dome tweeters did the sound of metal more authentically.   That was undone when I heard a speaker like the Josephs, which use a soft dome tweeter but on which drum cymbals jumped out to me as particularly authentic and metallic-sounding.
But if we are to stick with presuming for the moment the intuitions of how certain speakers sound due to their materials and build: something like the big fat ol' Devore speakers with their paper drivers sound particularly "organic," "woody/papery" where I just hear the wood in the body of an acoustic guitar, or the reedy tone of a reed instrument, or the vibrating wood of a cello.  The sound is not electronic-edged, hard, metal-tinged.

The Joseph speakers do an excellent job of providing the sonic benefits of a modern-sounding speaker with great metal drivers (woofer/mids anyway) so you get as you say that super clean, pure, "fast" sound.But Jeff Joseph has cannily designed in, or kept, a richness in the lower mids down that, gives some richness and body, which combine with the grain-free smoothness and clarity of the upper frequencies to make a very attractive, sensuous sound.

They don't sound as bang-on organic to me as the Devore (or my Spendor) speakers overall.  But they do surprisingly well and give a lot back by the sheer amount of beautiful harmonic content they dig out of a mix.


My Thiels, particularly driven by my tube amps, are a sort of in-between the Devore and Joseph sound.

I was listening to the opening track of the Bullit soundtrack which is great because it has guitar, drums, bass, and all sorts of different instrumentation, muted horns, horns, sax sections etc, flashing in and out out very dynamically.   On my Thiels it's a big, rich, dense sound, satisfying in it's own way.  There is what I'd call a "generalized organic tone" to everything.

However, that same track played on the Joseph Perspective2s had a timbral aliveness, variety and vividness the Thiels can't seem to match.The exact tonal difference of the muted trumpets appearing, the wood/metal sound of the saxes, the guitar, are so timbrally distinct and vivid it's sort of like beholding a timbral display of fireworks.My original Perspectives also do this.  Though my sense is the new Perspectives go a bit further.
(Playing Rush on my Thiels last night was a blast.  They go very loud without  strain and do rock with a dense, punchy balls-to-the-wall energy).

@prof , I apologize if this is wandering to far off topic but I was curious as to what amplifier you use with the Perspectives perhaps you've said but I missed it, and what they were using at the dealer with the Perspectives 2 ? 
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!
