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

Some new tests today 😅

I... must ... fight ... GAS ...

OMG, it's very similar 🙈🤣

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.

From your curves, it seems the BFL414 is more 414ish than the 214 which has a bigger dip in the mids and more top-end. L-Acoustics speakers are good but probably not the best ref monitors. Maybe its response curve or acoustics have a big impact on those results because the original AKG should not have those 100Hz 9KHz peaks.

You're lucky, you have a sweet collection of microphones!

Of course the peaks are really the L-acoustics signature preset curves. The low peaks probably disappear when you set monitor preset instead of FOH preset

The only way to read those result is not about frequency linearity, it's about compare différences between microphones ( not mine, it's at my job )
