Removing bums on woofer or replacing parts?

[ragwo]

This defect cant be fixed.
Only replaced.

i hope i will find cheap parts and let an expert do this. 350-550 euro is just too expansive for a plastic part.

It's not plastic, it's aluminium. The only way to find parts is to buy another faulty Phantom and use those parts. Devialet doesn't provide parts, nor does anybody else. If you try with vacuum, be careful not to rip the dust cap off, it's glued in place. I would not try to fix the dent just below the dust cap, you might damage the voice coil. If the voice coil gets uneven the woofer is ready for recycling. As I wrote earlier, I would leave it like it is. If you need detailed pictures and instructions on how to dismantle and reassemble a Phantom I, please see the link in my signature.
