Hi,

I have bought an used Synthesis Four FCR set.
2 of the 3 904Ti midrange drivers produce audible distortion and the moving assembly is somehow stuck in the magnetic air gap.
It doesn't sound like loose voicecoil windings. It sounds öike rust particles. A very "fine crispy" sound.
Is it possible that they used the older Neo magnet generation at that time with disassembling Chrome surface?
I am really sursprised and shocked...

Cheers,

Andreas
