@takato14, got some pictures of your mods?
Sure. They're really crude, but whatever.
I eyeballed the shape of the inner earcup, sans mesh.
The idea is that, when this is dynamat and not felt, there will be no bare, hard plastic exposed for sound waves to reflect off of. This should in theory reduce ringing and make things more coherent sounding.
However, I'm worried about the metal mesh, which is exceptionally dense and probably highly reflective. I'm probably going to have a secondary damping material in the cups to go over top of the mesh. I'd like to try replacing the mesh itself with something more open, but not only will that likely kill the bass response but the mesh is actually molded into the plastic, making it literally impossible to put anything else in its place.
I also intend to put filter paper directly over the driver. Hopefully this will be enough to kill the 6kHz peak.
As for getting the upper midrange dip to GTFO, I'll have to experiment with the capsule damping more. I suspect the outer ports are the key.
