You have no way unless you de-magnetize it!

I had Speaker Pro’s do exactly that on a 2440 with a broken throat for me, this month. $55.00 USD plus shipping.
They did a very good job.

The guys that came from Orange County Speaker Repair in CA.
A note of small consequence, I supplied the throat. They don’t have those.

I recall a thread here where a member turned some new throats, maybe that thread can shed some light Charles...
*edit* found it!

Once you break the circuit of a Alnico magnet it will loose half it's magnetism. When put back together the driver will be about 6db down from normal.

Yup. No doubt is must be re-magged once re-assembled.
