I don't have calibration microphone, so I can't really give precise answer about that. No idea what's happening on yours.

Superlux ECM VS ECM

My reference mics are cheap, but at least they are constents in a large range 😂😅🤷

 

[damien]

oh yeah, definitely not a problem of reference mic in your case

What’s the source / method ?
Interesting ! For some reason I would have thought that all of these mics would have more extended freq resp under 60hz and over 10Khz, no matter if original or copy or whatever.
Thanks for posting this !

The source is processed L-acoustics X12 speaker (59Hz-20kHz, that's why nothing appear in the low range), pink noise Smaart generator, Channel 1 microphone / Channel 2 ref . Simple Scarlett 2i2 as audio interface.
