No it's more like a K67/87 (hole pattern at least, straight lines, not circular) with K103 derived backplate.

If by single layer you mean single diaphragm, there has to be a non-sputtered ‘dummy’ diaphragm on the back side to keep the chamber insulated.
I wasn't sure how to put it, as the usual K47 cheaper clones have 2 layers of the backplates?
It is unique capsule, single backplate, k67. I appreciate it for being unique. It has frequency response kind of in k67 ballpark, but pattern response similar to k47.
I modified one here, you can see the frequency response before and after the mod.

K67 capsule mod for less high end
I had this capsule lying around, so i decided to do a mod to it based on b&k paper. The capsule is a k67/k47 hybrid, but the principle is the same for almost any capsule. This one can "easily" be modded, as the diaphragm is glued to the tensioning ring, and won't collapse when detached. The...

None of the three in that image is a K47 clone.
K67/K87 clones all have a "square grid" of holes; K47's have a concentric-circle pattern of holes in the backplate.

And only one backplate!
This is from takstar. Interesting single back plate capsule with no chamber. I remember it sounding pretty decent?
I meant to say 87!
That's a instant buy! I'm a huge sucker for takstar anything
Thanks. I'll check it out.It is unique capsule, single backplate, k67. I appreciate it for being unique. It has frequency response kind of in k67 ballpark, but pattern response similar to k47.

Oh, I have also used this one before, and the frequency response in the anechoic chamber is about this. It is not very accurate below 100Hz
If that is the response in anechoic chamber why is there so much smoothing, and why isn't it accurate below 100hz?

You are correct, but I’m failing to see the connect here. I may have missed something.

Because it is not a particularly standard anechoic chamber and there are not many sampling points, this curve has been smoothed, but it is also relatively accurate and can be referenced
Actually, most anechoic chambers below 100HZ are not very accurate
Wouldnt that mean the measurement is not valid then?

So what kind of measurement results are valid? The results vary under different test variables, and the test curve can only be used as a reference. Each product test has its own differences, and this data may not be qualified as an accurate measurement, but it is not a problem to use it as a reference
I have posted the measurement of this capsule before, here it is again. The purple line. It is anechoic measurement, 100% accurate, and absolute. I'm not sure I understand what Ekaterina means. That is why we have calibrated reference microphones, so that we can eliminate variables.

This is somewhat different from what I remember. Can you tell me how you measured this capsule? I remember using a Scott circuit test before, with a standard sound source placed at a distance of 50cm. Thank you
