A bit of initial data: bass resistance some 2.5 Ohm, mid some 7 Ohm
and piezo some 3.3 Ohm.

It's not a piezo, or there's something wrong with your measurement.

Or they put a parallel resistor inside it. More data coming up, from the
frequency response it idt definititely is a pieZo.

Bulb resistance around 1 Ohm.

[ccrap connection to bulb]

I'd just replace the bulb with a soldered in polyswitch,

Have you ever heard the instant pedagogic effects of such a contraption?

or at least
solder the bulb instead of a socket.

Nah, it either stays as it is or gets replaced by a piece of wire.
