Nothing special about the original at least this model, generic k67 capsule, not tuned to any special spec, sounds and measures like one. EF12, generic Apex transformer, stock PSU.I always wanted a JP mic, but could not justify the cost...so excited
What is it about this capsule? It looks unusual.
And in the "related" stuff just below, i noticed this:

The images i posted are from the real deal. At Ali they sell just the body. I edited my comment to avoid confusion.
I am really skeptical about the loss of capacity because not the whole diaphragm is covered with gold!I'm really skeptical about how much weight actually gets saved by the discontinuous gold sputtering
Increasing the (stationary) capacity isn’t necessarily a good thing: the diaphragm doesn’t move that much near the edge. According to the AIP Handbook, the optimal backplate diameter of an edge-terminated omni capsule is calculated to be 81.6 % of the membrane diameter. For a center-terminated design, the reversed argument might also apply? This interesting thesis (p. 109) has a section on this as well, with some measurements.I am really skeptical about the loss of capacity because not the whole diaphragm is covered with gold!
Ahh ok, I must admit I did not know that company and its products! Thanks for info, you never stop learning.As the title of it says, it's a clone of (or at least inspired by) JZ Microphones' "golden drop technology" capsules.
It is not the stationary capacity that is the point here, but the fact that there are a lot of gaps between the 'drops'.Increasing the (stationary) capacity isn’t necessarily a good thing:
I have no idea what the gaps between the drops are supposed to do, other than make them look interesting.It is not the stationary capacity that is the point here, but the fact that there are a lot of gaps between the 'drops'.
Lower capacity means also a lower change in capacity (due to the audio vibrations of the membrane) and thus lower output.
What’s up with the “new” EF11,12, 14 tubes? AliExpress has numerous listings for them too.

I'm really skeptical about how much weight actually gets saved by the discontinuous gold sputtering (thereby allegedly "improving transient response" and other marketing malarkey) though...

Not sure how this could be the case. Transient response is determined by diaphragm mass. It is also inseparable from frequency response. This is physics, even though the marketing often advertises something else. The mass of the diaphragm is not affected by the miniscule amount of gold. The only way this could be the true is if they used significantly thinner diaphragm material. Which could be the case. SDC doesn't necessarily have better transient response, this is again dependent on other parameters. Transient response is very difficult to asses without doing objective measurements. Even some modern ribbon mics have better transient response than some older SDCs.1 - The have exceptional transient response. Almost a sdc like transient response, but with the voicing of a LDC. Makes for a genuinely interesting, useful mic.
