Large format alnico driver.

[John]

Hi Can anyone explain in detail how a large format JBL driver such as the 2440-2441 is disassembled??? I have a cut-away picture of one and figure they are press-fitted and then regaused, but would like to know the procedure used to break it down to the parts that make up the driver.

[Mr. Widget]

They are held together by the sheer power of the alnico magnet. They are not user serviceable, other than replacing a diaphragm.

So if i was to deguass the drivers would they fall apart??? Is the top plate not a press-fit?
I should mention i picked up a pair of 2440,s plus a ti.dia. in Tulsa the other day for $20.00 US. ,they have broken throats and a little bit of corrosion,and i thought if i could take them apart and clean up the castings and then maybe drop them off at orange county they could re-assemble them. At the price i paid i got nothing to lose,in fact maybe i could get them sliced in half for display,hey Don if i go this route i will give you a slice Any one else want a slice?

How would you handle a neodymium driver?

The word neodymium scares me.
In fact, it sounds downright spooky!
I would wear this and use a long screwdriver so I could keep my distance...
