Is it okay to talk around your speakers?


When a system is not on, should you avoid making any noise near the speakers? I am thinking about back EMF caused by the speaker cones moving and then sending voltage backwards into the crossover and the rest of the system - could this cause damage or even minor degradation to the sound quality after a while? Do you unhook the speakers when not in use just to be on the safe side?

I put cryo-treated tin foil hats on my speakers to prevent any bad vibes from penetrating.
Wow, I thought I had heard everything, but that's a new one. I certainly don't think normal conversation of any volume would create enough movement of the drivers to cause any back EMF, especially without an electrical signal entering the cones.
I have covers made out of the same material as my argyle socks that I use when they're not on. I don't even want to look at them unless they're playing.
I never talk around my speakers. Don't even whisper. Even thinking near them can cause problems. Be careful what you have on for jeans at the time also.
I wouldn't worry about it too much.After all the world is coming to an end in a couple of years.
