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.

theres no evidence these speakers are better than a diy pair at a fraction of the cost.  or is there?

Can you figure out why DIY speakers are a fraction of the cost of retail speakers?  Even IF they happen to be as good?
Can you figure out why cooking for yourself at home is cheaper than ordering at a restaurant, even if you can make a meal that tastes as good as the restaurant meal?

"theres no evidence these speakers are better than a diy pair at a fraction of the cost. or is there?"

This line of reasoning makes little sense. Most anything one makes themselves will be cheaper than that made by someone else.

Once anyone says that their DIY speakers sound as good or better than a commercially produced speaker, I'm interested in knowing who else has heard them and agrees with the builder's assessment. I readily admit that ownership of a particular brand reveals an inherent positive bias towards that brand. But, the ultimate bias is for one's own creation. If others aren't asking the builder to make them the same speakers after they hear them, then the speakers might not be as good as the builder believes.

Yeah...Magico’s using those cheap drivers with their under hung speaker designs. Anything to help lower distortion is a good thing in my book.
I didn't say their drivers are cheap, just that the use of underhung voicecoils is not remotely uncommon these days, nor are they expensive. For example, some of Monitor Audio's entry level stuff has underhung coils. The potential for greater expense comes from underhung-coil-drivers of unusually high excursion and power handling. Makes for a larger/heavier motor assembly. Like all choices in speaker design, it's a matter of tradeoffs. An underhung coil is more linear (in theory), but when pushed to the limits, the resulting distortion is quite nasty compared to the softer distortion of an overhung design.

I think people say that about JA Pulsar's because the drivers are available on OEM supply sites like Madisound and it isn't using anything unique that a DIYer can't easily replicate, such as a custom waveguide.
