A way to control bass response on the AKG D130

At your own risk.


The beautiful metal mesh can be unscrewed carefully.


The capsule detached gently from it and from the mic case.


Then attached gently to the mic case.


Then the metal mesh screwed back but half way.


Singing voice was found to be more natural at 4in at this point.


More screwing increases bass until normal mic spec when all the way tight.


This adjustable bass cut seems to nicely compensate for the voice effort effect.


When we speak softly the spectrum of our voice increases much more on bass and treble frequencies relative to mid ones.


Then if we reproduce at higher levels it sounds unnatural to out brain.


The Fletcher Munson curves make it even worse. Our voice reproduced by then sounds too bass heavy and unnatural.


In pop music in many instances we reproduce voice much louder than when it was recorded as the singer might like to sing effortlessly and the listener might like to listen relatively loud.


This little hack makes a variable bass cut without modifying this amazing microphone in any way.
