Hi solderdude ! I would like to know if it would be possible to make a passive filter for the Sennheiser HD 599, something like this: That is the EQ that I'm using and I would like to know if it would be possible to replicate it with a filter. Thanks in advance. Regards.

That is not possible alas. It would require a impractically huge inductor and capacitor values.
Instead you should modify the driver by adding some extra damping to the rear. That will achieve exactly that.

solderdude Thanks for the response, I imagined that it would be something very complicated. I have another question. Do you think it could be possible to replicate the following EQ for the HD 560S?

I will have a look but suspect the Q at 9kHz is too high and the 2 filter sections are too close together.

It's important to me to reduce the 9kHz peak, as I find it very sharp and annoying after a while of listening (and quite fatiguing). I 've tried to reduce this peak using some toilet paper and even some foam material, but the peak doesn't go away at all and I'm also cutting off a lot of air. That is why I'm interested in reducing it with a filter, since that way it would not affect the rest of the frequencies that are correct for me. I might look at lowering the value of Q to 6 if that would be easier for you. Regards

I can make it. A potential problem is tuning it in practice to that exact frequency due to components having a tolerance. Might take me more time to EQ it exactly. It will have 2 filter sections in a cable so minimal length will be around 45cm.
For more details perhaps use PM or e-mail or the contact form on the website.
