RE20 qui grésille > Trop de pression acoustique ?

Moi j'avais acheter une petite malette d'embout tournevis et clé mac alister chez casto et nickel , le mien je lai acheter d'occasion aux USA g remplacer la capsule moi mm car le micro était dans un état..... lol

My PL20 sounds fine on lower volume sources, but on a bass cab it distorts like a flappy speaker...
The foam looks OK *except* it's not positioned quite like the pictures from the original post here. The foam that surrounds the capsule comes out about 1/2" from the mic body, to the very edge of the capsule itself:

can anyone confirm that this foam is supposed to only come to the edge of the body, as opposed to the edge of the capsule?
I did order new foam to replace, so I might just trim this foam to find out.
I hope it's not a bad capsule...

Hmm. nope! removed the excess foam and still get a muffled distorted bass sound with the mic when I turn up the amp (still only on '3' of the amp's volume knob).

On to taking it apart.
Anyone else had a similar problem with louder low end signals? Any solutions?

Well. Put all new foam in and I'm hearing the same buzzing when I record in front of a bass cab. I've compared it to an SM57 on the same signal path, which sounded as it should, no buzzing.

I took a good look at the capsule and diaphragm, it did not appear to have any problems.. Doesn't move or wiggle freely, is positioned as it should be, etc. The resonator disk does have this fine mesh glued on, which is slightly loose in places and itself might be making the buzzing noise, but I kind of doubt the light mesh would vibrate and create that noise.

Bummer! might have to send it along to EV.

I own three RE20 microphones and one of them gets a distorted sound when using it as a bass drum resonant head microphone, the other two sound great. I did send this microphone away for a foam transplant about five years ago and when it came back, I just tested it on my voice and it sounded very nice, I didn't test it on the bass drum until I tried using it about two years ago. So I know what you're talking about but I don't want to spend tons of money getting it corrected as long as I can still you it on spoken word. The microphone was never mishandled and looks almost like new.

I found what makes the buzzing and baby rattle noise. There is a phase plug under the diaphragm. Apparently EV needs to go back to school when it comes to glues and foam. The only repair is to replace the the entire cartridge. The diaphragm could be removed but you must take incredible care. You can probably use a razor blade or X-acto knife to remove it but 1st it has to be de- soldered . Use the smallest soldering iron tip you can find, sometimes audiologist have them for working on hearing aids, most soldering tips are too big and burn the wire. Once done center the phase plug and use a drop of super glue. The problem is what to use on the diaphragm. I default to rubber cement, but I don't know it's effect on the material of the diaphragm. In other words unless you have way too much time on your hands , it's time for a new mic.
