Is there any way to create a passive low pass filter for audio using only inductors (including their cores of course), not capacitors or other devices?

All right, I have just realized that a single coil in series can cut-off higher frequencies and leave only audio. This is not sharp but the audio and MHz range of frequencies is too far appart.
Please correct me if I am wrong.
