Thread: What causes speakers to pop?

Not a bad idea but you don't want to repeatedly turn the fridge on and off, once is ok but give it some time before turning it back on again. It's hard on the compressor (I believe).

Problem is if it's the fridge, what can you do about it?
I guess you could try a different plugin that may not be on the same circuit as the fridge.

Unfortunately, after several months, I still haven't been able to track this issue down and I rarely use my surround sound due to the popping. I have tried unplugging all other electronic devices in the immediate vicinity and the speakers still pop. The one thing I did notice is that the popping never occurs until the system has been turned on for awhile (anywhere from 30-60 minutes) and then after that there are occasional loud pops that occur as one loud pop through all speakers. The vents are clear and the room is fairly cool, so I would be surprised if the receiver is overheating, but is there anything else that could build up after a period of usage in order to cause popping? This is a standalone home theater system (DVD player is seperate), the Panasonic SA-HT40, which I used for about a year before starting to experience this issue.
