I am not familiar with microphone design (and its electronics)...since this is the first transducer that converts sound (accoustic) to an electrical signal...then recorded...why doesn't anybody make the inverse or the same design as a speaker. A speaker is a tranducer that convert electrical to accoustical output.
Are microphone diaphrams..push-pull design...any magnets....piezo...?
I also read that some antique-classic microphones are preferred over new ones. Aren't the lower mass modern design better...lower mass = faster stop/start...higher sensitivity...less coloration?
How close are electrostatic speakers design to microphones?
Ribbons? What about horns?
Why doesn't anyone make a giant microphone...but instead of receiving sound...make it make the sound!
Just a thought!
