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.

One of the benefits in the Magico design is the use of underhung voice coils to lower the distortion..expensive..but worth the cost!
Nothing special, rare or expensive about an underhung voicecoil. It's quite common, even among some relatively cheap speakers.

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.
