Hello my name is jeroen and since today i am a new proud owner of a pair of these beautifull speakers.
I had them before so i know how then can look.

I got them tday and when i removed the grill there came also the problem, they are really dark yellow, from nicotine ..... this was some serious smoking .
I do not know if there is a protective layer over the white/beige conus or is it only paper ? this seems inportant to know so i know how to clean them.
And offcoures this is the next question , does anyone have experience with this cleaning proces ? did it work ? , hope someone can help me kind regards jeroen
