"haircut"="hairline fracture"

Thanks David and other,

We have a laser welding machine in our factory.
Let see how it works.
The Le 10 A`s are not for a new project now.
May be later. Just want to refoame both.

Gee ,,,

Real Nice Work, Eckhard !

Any chance of it rebreaking if you over-torque a screw/bolt into the hole ?

or is it quite strong ? ( I have a broken le10 basket, just like yours was )

Thanks boys,

I´m very happy about. Good work from our man on the lasermachine.
Earl, it`s quite strong. Hard work to get the old foam off.

Nifty repair job, Eckhard.

If you don´t know, you can`t see that the basket was broken.
The broken part is on top right of the last pic.
How is the magnet motor fixed to the basket ?

Lets rock !!

How is the magnet motor fixed to the basket ?

From that generation of transducers; usually lightly glued and screwed/bolted into a tapped/threaded top-plate.

Since the late 90(s) , this method might have been altered. I had a 2012HPL start to lose/shed it's magnet about 15 months ago. The problem is weight related. The 2012 magnet is about 7 lbs heavier than the 2123 predecessor. The basket/frame is identical. This heavier magnet was glued and only riveted ( aluminum ) to the top plate receptacle/bore-holes ( a bad concept from the get-go to count on aluminum rivets to hold all that "cantilevered" magnet weight ). These little speakers ride around in "foamed" cases.
