I'd tend to wonder if the workers rerouted any power wires near the
panel, speaker, or any interconnecting wiring, and if that power wire
runs something that draws a lot of power.

Try to figure out if the pop coincides with the switching on or off of
any appliances, such as the fridge, or an electric (baseboard) heater -
anything that could produce a voltage spike when toggling power.  It
doesn't even necessarily have to be something located near the affected
components; all it needs is for the power feed to that device passing
too close to the alarm components or wiring.
