So much for getting good working MW6511. They are in fact MW6511, 2 of them marked CRS+ on the backs. Upon first inspection, they seem to be in good shape. They were wrapped in a ton of bubble wrap. The box was not damaged. The way they were wrapped, it would seem impossible for them to move around at all. I have looked at the magnets...now not sure what i'm "supposed" to be looking for, but i don't see any signs that they moved. But both of them are dead. The voice coils are frozen in place..and i mean FROZEN. They don't move at ALL. I tried the 9 volt trick on them. You get a little click, but thats it. NOTHING moves at all. Now i could see if the magnets shifted, then you'd get scratchy stuff, but you could still move the voice coil. At least some.
These 2 drivers you can't move anything. To me, these drivers were far over driven, and fried in place. Little or no chance these worked at all, before they were packed up and shipped.
If anybody has any idea's on these drivers, would love to hear them. I don't see how i can fix them even if it was magnet shift. But i also don't see them completely FROZEN in place due to that either.
