Morel MDT-44 Voice Coil

PDude · 21st February 2008, 06:34 AM

Trying to replace the voice coils after an overzealous 25 yr old used the car.

I need a ferrofluid 101 primer. I assume that is the black/gray stuff is on top of the magnet. How does this stuff stay out of the voice coil gap, or does it matter?? The little white felt circle just rests on the top of the magnet, with nothing holding it on? Is the ferrofluid all it's cracked up be?

Should I just stick on the replacement assembly and wire it up?

Ok, had a little time to do some checking.

The ferrofluid is supposed to be in the gap, I thought it would drag or slow down the coil. So does the fluid on top of the magnet need to go back in the gap, and how.

The felt piece should glued back onto the magnet?
