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.
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?
