/diy/ - Do It Yourself

Hello, I'm worried I might have just done something incredibly stupid and damaged a very rare and expensive speaker. I have an electrical arc lighter that I was playing with in my room (pic very much related). When I decided to zap a metal chain sitting on my desk. When I did this all my usb attached devices disconnected from my computer and this strange visual distortion consisting flickering static and waves appeared on my monitor. At first I was worried that the current had crossed from the chain and traveled into my desktop. I experimented some and determined this wasn't the case however because the same effects were observed if I stood and held the chain while zapping it. The floor is carpeted and I was wearing socks so it would have been impossible for it to somehow travel down my arm, down my leg, through the carpet and into my monitor,mouse,keyboard, etc, plus I would have definitely felt it traveling.The chain must be producing electromagnetic waves when being zapped by the arc lighter, these waves traveled through the air and disturbed the normal functioning of devices circuits. I'm worried now because after I played with this I noticed my right speaker developed a strange quiet yet noticeable buzzing noise. That speaker no longer plays correctly at all, it sounds almost like when a speaker has been blown out or badly damaged. Bass no longer comes through the right channel at all and the treble is very faint and distorted. I'm worried the EMF waves generated by the chain somehow permanently damaged the crossover circuit inside the speaker box, maybe it damaged a capacitor somehow? Please, I feel like an idiot, I was so baffled at what I was seeing on my monitor that I kept playing with chain and arc lighter that I kept playing with it, I had no idea something like this could potentially happen. What do I do? How do I trouble shoot this issue? These speakers are incredibly rare and high quality and I've cherished them for years.
