Dismantling of 2441 driver on video!

[panos29]

Here is a guy dismantling a 2441 driver and replacing the plastic throat with a new bronze one. My question is the obvious, since after this operation the magnetic circuit of the alnico magnet is going to be open, my understanding is that the magnetic force is going to collapse or loose part of its strength. Am I right or this operation is normal and can be performed with no loss of magnetizing strength?

There is no "circuit", it's a permanent magnet. It's not an electro-magnet in which case the field is maintained until the circuit is broken resulting in total collapse.

I really think you are mistaken, if you search in this forum you will find in so many threads that if you break the magnetic circuit by removing the plate of the driver the alnico magnet looses a big part of its power.

Interesting, but where to find this bronze tube?

The guy posting the video is trading these on ebay.pl

100 euro per pair, not that bad, but there is the catch of magnetization strength loss, maybe it can be installed through the front?

More10 has done this upgrade ....

demag the driver , dismantle it , replace throat and remag to original spec ....

This is the obvious, what if there is no availability of mag-demag utility in a country?

Send it to me and ill help or send it to Italy or Berlin .....
