Back to the actual topic, how would you deal with such a situation?

Does this protrusion of the membrane material have any negative effects?
Trash can, need for action or just ignore it?

PS: I didn't pay anything for this Rayking capsule.
You can ignore it, no negative effects. But you can easily remove it with an exacto. It's a good capsule.

If it works, it works. If it sounds good, it sounds good…
There are many cases where a capsule, or any gear, checks those boxes, and yet ugly side, anomaly, error hapens when you expect it the least, and you have no idea where it came from. This is especially true for any kind of transducer.
 
Is it me, or does that Golden Drop pattern of spots seem like a dumb way to make a diaphragm?

My impression is that the weight of a microscopically thin layer of gold isn't significant, and if it were, you'd be better off with a somewhat thinner and partially transparent layer covering the usual inch-wide circle. (And maybe a pattern of small not-gold spots that coincides exactly with the backplate's blind and through holes, where you don't get significant capacitance anyhow; save the gold for where the backplate is close to the membrane.)

Their marketing reads like utter nonsense.

“Imagine a capsule that is wholly sputtered in one layer; it just resonates as one piece,” Evelis says. “But in our case, we have dozens of gold droplets, and they are all resonating. It makes it more accurate, more precise. Can we prove this in scientific tests? Theoretically maybe, but the main thing is that if you listen to any of our mics, you really hear the difference that our mics are clearer.”

Nobody said they weren't good microphones.

There's just a greaat deal of scepticism that the the Golden Drop sputter offers anything superior to conventional sputtering. Especially since they don't offer any technical info that would support it.

A strong whiff of 'something different' just for marketing's sake.

I would differ on the point that the Walkman was successful because of a markerting pitch; it's story is in no way comparable to Golden Drop mic capsules. The Sony Walkman was a truly game-changing revolutionary product that changed people's lives becuase of what it actually did, not because of what marketing said about it.
 
I reserve the right to be disgusted with marketing, if it's BS. Some may admire effective BS, but I don't particularly.

But we should probably stop polluting this thread with issues of marketing and whether the Golden Drop shtik is or isn't BS. There are other threads for that, including this one, which I'd missed. (Sorry for my part in the derail.)

So K (sorry I wrote Paul), I genuinely would love to hear about your personal experience as part of Sony when Walkman launched, both before and after the amazing marketing campaign. I admit I only spent a couple of decades with the company, and it was years after the Walkman launch, so since you were there when the product was brought to market, I'll defer to your first-hand knowledge. As I said, I'm more than willing to admit I could be wrong.

Paul, you are right. I'll stop polluting and happily move to the suggested thread or start a new one. Thanks. Also, you have every right to be disgusted by brands selling products solely on marketing, BUT sadly, it's generally the rule and not the exception, and it's only gotten worse over the past twenty years.

I have no knowledge of Golden Drop's value as a technology, and as I said, it could very well be amazing and actually make a difference. I was pointing out that it has the potential to be an excellent story to sway potential customers, even if, by itself, it does not impact the microphone's performance.

The moderator should probably delete this detour or move it to the suggested thread.

Hey, it turns out I can delete my posts! So I took Pauls advice and will move them to a more relevant thread since I agree they are not on topic. My genuine apologies to the group for distracting from the actual intent of this thread. Gomen'nasai

I was just out of High School, about to go to College when Walkman came out. I honestly have no memory of the marketing; they were just suddenly everywhere! One listen to one, with those (for their time) impossibly tiny headphones, and one couldn't believe the quality of sound from such a small device; the first tape deck with Dolby, that showed what cassette was capable of had just come out a few years before, and was a huge, heavy machine the size of a typewriter (the Advent 201)! The fact that Sony was able to shrink a reasonably high fidelity tape player down to a size barely larger than the cassette itself was astonishing at the time.

The Walkman phones themselves were a revolutionary product; I think they were the first to use neodymium magnets, which is why they sounded so good for something so tiny and lightweight. If everyone had to use the heavy, clunky phones that were on the market at the time, the Walkman would not have had such a huge impact. It was the combination of the lightweight phones and small player that made it the must-have consumer product of the '80s.

Now, back to our regularly scheduled thread . . .

Here a picture of the Oktava MC-900 LDC capsule (cardio only). CK12 style.
I don't own this mic and never tried it neither : do some of you know this mic ?

It has a good self noise and good sensitivity and costs (only) 109€ (taxes included but not shipping)
Maybe a good challenger for those who do voiceover with an affordable mic ? (AT2020 / P220 / NT1A / etc...)

Their website provides an AB test with NT1A

This is a mic I'd definitely try if I have a 100€ to spend in mics at this time...

I had the mic to test, very high quality for the price, good Wima capacitors, sounds really good too! (for this price range)

This is not a ck12 capsule, is a k67 with edge termination.
Seems like any other Chinese k67 edge terminated available in the net...
However, if well matched with a good circuit can deliver usable results.
Used in past as replacement and I report very emphasize high end.
 
Just cut it?
Yes, that's exactly what I'm going to do. I was a bit unsure at first, as this is a delicate area and I have no experience with it, but after member kingkorg's post, it was clear that I would simply cut it away. Thanks for the feedback anyway!
You can ignore it, no negative effects. But you can easily remove it with an exacto. It's a good capsule.
