Background 50 or 60 Hz buzz can be radiated from nearby wiring or conducted. Grounding is important but that can also be a cause. I suggest you search accidental hum loops.

Poor or faulty power supply regulation or smoothing can inject a mains hum into audio. This would need checking with an oscilloscope which could also be used perhaps to help search for the source.
Radiated hum can be picked up and injected into high gain amplifier inputs and long leads, poor screening and impedance mismatch can make things much worse.

I haven't helped much but I hope I have given you food for thought and further research.

Little goes wrong with a speaker unless it has either been overloaded or subject to damp, extreme dust or has sustained physical damage from some sort of accident.

A rough test is to move the speaker cone gently through most of it's travel using an even pressure simultaneously on various places around the cone, I use my fingers.
It should move smoothly without any resistance and most importantly it should be completely silent through the largest or smallest movements.

If it sounds scratchy, the speech coil is either off-centre or it has suffered damp or dust and dirt has ingressed into the air gap or the chassis has become distorted.
If it is silent and electrically sound it should produce normal volume.

There was a time when loudspeaker repair, overhaul or adjustment was routine but these days it isn't economic except for the highest quality and replacement is best.

After gaining access to the interior wiring of the speaker cabinet I suggest further testing it by wiring it direct and leaving out the crossover if it has one.

Make sure all fragments of the original programme are uninstalled before installing a fresh driver.

I am currently searching for support or repair/part replacement options for this microphone for which the problem in my case is very obvious. The capsule is cradled in a rubber mount which affixes to the top of the mic body by three plastic posts. One side of the capsule has a soldered wire, and the other is comprised of a contact pad that mates against a spring pin in the center of the top end of the body. Two of the three posts broke and there is not enough tension against the spring pin (also called a "pogo-pin") to maintain a solid connection. The connection is good enough most of the time for the sound to get through, however popping noise which is fairly random occurs as well. This situation can be easily observed by unscrewing and removing the windscreen and visually inspecting the mounting system. My thoughts if unable to get a cost effective repair made or replace the parts is to drill into the plastic mount and glue stainless steel pins of the same diameter (possibly from scrapped HDD mechanism or similar) in the place of the previously existing plastic pins.
