I am not sure if i got the point across. The comparison between CK12 and Rodes capsule was to show they have nothing in common even though they are both edge terminated.
There are a lot of similar capsules to Rode's that claim they work great as CK12 alternatives, and that can't be further from the truth.
Tim's capsule is not overly bright, keep in mind the graph is 5db per division, it's "zoomed in". And it's response is nothing like chinese k67. Notice the huge low end response, slight scoop in the mids, and shape of the high end. Keep in mind C12 is brigter than u47, u87, u67...
This was not to show that Rodes capsule sucks, as i would start with capsule mod first instead. It is probably the flattest mass produced inexpensive 34mm capsule currently. Which is what a lot of people were after for years, complaining about overly bright k67s.
So Rode did it, and this is probably why they compared it to u47 in the video. Not to say they are alike, just that their latest model is not overly bright.
Additionally, new production technology helps with consistency, and it's a dead quiet mic. For the price i think it's a great mic, and i'm just looking at ways to improve it if possible.
