Dynamic mics - why so difficult to reproduce?

[soapfoot]

The NS10 driver works especially well for that purpose due to its F(s) of (IIRC) 58 Hz

When it’s excited, it basically resonates at that frequency, which some people find flattering for kick drum in certain applications

It’s not neutrally “capturing” the acoustic drum so much as supplementing it with a largely-undamped low frequency resonance

A different speaker will resonate at a different frequency (its own), which may or may not be as helpful

You’d have to look up that particular driver’s T/S parameters to know what’s actually going on

I worked for a company that wanted to make a dynamic microphone for the mass market
we bought dozens and dozens of dynamic capsules on the shelf to get closer to an SM7, and it was a huge fail, impossible to have a good capsule in China! if you don't put 150k€ of research and development for the design and build your own winding machine and membrane manufacturing it's over you will never have quality,
in my opinion it is 10x complicated to manufacture than a K67 static capacitor capsule!

Sylvia Massy (sic) "American record producer, mixer, and engineer" (says Wikipedia) sometimes/often uses a big speaker (as in guitar amp speaker) as a bass microphone to pick up guitar amp speakers, as described in a video interview last year with 'SoundOnSound' magazine.

This is both true and old news. Legend has it the first use of a subkick was for “rain” by the Beatles.
