You cannot. You would need to remove the cone and voicecoil. Then strip the magnet and its polepieces from the frame. Then dismantle the polepieces to get the magnet on its own.Originally posted by legac@Jun 5 2005, 03:02 PM
I would appreciate if you could tell me how to remagnetize an 12 inches old loudspeaker without detaching the magnet from its iron frame.

It would then be possible to remagnetise it, but it's not a job for an amateur because specialised equipment is required.
Assuming you could get that done, you would need to reassemble without the voicecoil 'scuffing' the polepieces in their anular gap. I would not try.
Why do you think it needs remagnetising, anyway?
The magnets are magnetized prior to assembly. One magnet geometry can be used for different speaker geometries while requiring only one set of fixtures for the magnet type. Otherwise, more fixtures would be needed.Originally posted by legac@Jun 6 2005, 07:15 AM
I think the loudspeaker producers do not magnetize the magnet before assembling. Perhaps they do the magnetising after assembling by using a very strong electric magnet?
