Is LF driver 122A an overhung or underhung design?

Previous owner of Horizons had a Pioneer SX-1250 back in the day.
I reckon that thing could send some current through the coils.
How likely is it the 122A magnets could be discharged?

In close terms, the 122A has about a 1/4" tall top plate, with about a 3/4" tall voice coil winding. The voice coil hangs outside the top plate about 1/4" in each direction, at rest.

As for the magnet- unless the driver has been blown up before (i.e., burned up/overloaded and then reconed) or dropped severely, then the magnet should not be significantly discharged (ie, should be near original strength).

Regards,
Gordon.
