The power grid where I live is very reliable, I haven't experienced a blackout for years. However, my own appartment is very small, and all electrical outlets seem to be connected to a single line. Every time the fridge compressor wakes up, I hear a pop from the PC loudspeakers. All PC components (including the loudspeakers) are plugged into a power strip with integrated surge protection.
Are these power spikes harmful for the speakers? More important, are they harmful for the PC or the monitors? Is there need to do something to prevent them, and if yes, what can I do?
