Well,
here I go...

I had a problem like this times ago.
Old loudspeaker boxes. In portuguese the faulty part is called "Divisor de Frequencia" (Frequency Filter is it?), a device that is mounted inside the speaker Box, with 1 or 2 potentiometers, that are able to equalise the sound. I supose it is called "crossover" in English.

Some of these potentiometers are wire resistors, high Current I supose. Well, one of my faulty loudspeaker box was with this potentiometer with some kind of problem; when volume (that is, Voltage AND current) come hight, sound crackled...

HTH
