Soliloqueen's k87(k67) and k47 capsules

[neowalla]

I'm also beginning small volume production of some test m7s, 10 or 15 or so. I might send out a loaner to get some opinions on how to tune it.

Oh yes!! If you start making C12 capsules someday you will become my sole source for LDC capsules.

check this out. Here are a few flat k47s with the new metal, relative to the target, and for fun, a somewhat dark k47v relative to the same target at 1/48 smoothing:


We've reached best in class performance here. The differences in sensitivity are exclusively due to the plastic spacers being too squishy. We've reached zero metal influence and near-zero diaphragm tension influence on the capsule response.
Matched at 0dB:

Let's zoom way the hell in:


These remaining differences are broadly due to minor positioning differences in the test microphone due to our rig being kind of jank and having the test speaker way too close to get over the noise. We've reached the limit of shop floor testing.

That‘s pretty impressive!
