Hi all, I'm new to these boards but have owned Klipsch for years. I have the 7.1 Synergy series and Pro Media 2.1 for my PC. My issue is one of the speakers or speaker wire has died. It started out all of the sudden with a hum and then as I removed or went to put theplug back in (on the speaker side, it's a mini jack I believe) it would spark and now doesn't make any noise or sound. Is it the speaker wire or the speaker itelf? Thanks in advance for the help!
