You need full number?
For some reason I still like dbx more, as it is smaller, has dedicated box. Also, they differ in sensitivity, do not remember which one is more sensitive, but difference is substantial. Need to retune when switching.
I am in talks with local sound guys to simply compare both mics to the one they own, I think that will be some NTI, hopeful that will happen this-next week.
This is a sample of an older model:
You have the new 2024 model-

Compared to the previous electret condenser mic model, this model has slightly lower max SPL (124dB vs 128dB) and lower SNR (65dB vs 70dB).
BUT
I wonder what the calibration file looks like. Or if it's even needed? MEMS can be at flat as a pancake...

Except where they aren't. Both LF limits and HF resonances need to be addressed. The plus is that they are very similar from unit to unit. Bill Waslo showed how to electronically compensate a MEMs mike.
I shipped Dayton back to seller. And thought the story is over.... But!
I went to the good sound guys on one company, which do some measurements at live venues. To be precise - not measurements, but pro sound rent, sales, and so on. Measurements probably is not their primary task. The guy said, that requirements are totally different in preparing for concerts.
We compared my 2 microphones to NTI M4260.
NTI vs Sonarworks
NTI vs dbx should be even more difference in higher freq, up to 5. I cannot put curves one on another the same way
NTI mic is ~10-12 years old, I have no calibration file, the owners probably also do not. It is massively more sensitive. Typical curve from manufacturer:
Which to trust and use for everyday:
Old NTI without cal file?
dbx, also with general curve?
Sonarworks with calibrated file?
dbx or sonarworks but "calibrated" to NTI?
Right now I am leaning to pure dbx, because it is a little more sensitive and little less noise. Also, 1-2 db in highest 10kHz+ frequencies do not play much.

get both mics calibrated, or calibrate them yourself using a SB Acoutics SB19ST-C000-4 Tweeter which is flat from 1K to 20K + or - 1dB
As long term stability and influence of humidity is not defined, I would guess that a 10 year old M4260 would benefit from
calibration

Calibration is nice to have and gives some peace of mind.
If we get practical, mainly for speaker building,the reality is that eve the average low cost, 30-80$ electret measuring microphone, is very linear from 80-12000 Hz. Which is the most important region, for speaker DIYS.
Get a Behringer, Superlux, Dayton, mini-DSP or any other known brand and you can be quite sure to get your speaker and crossover right.
