I was pushing my LSi's pretty hard today and after about 20 minutes worth of Aerosmith, I started to get this wierd melted wire smell from both towers. My Sunfire Cinema 425/5 is still fairly cool to the touch and both speakers were sounding just fine, but I shut everything off just to be safe. I pulled the crossover out of one of them and it looks fine, but hot to the touch. Did I pull the plug in time? Any ideas on this one before I plug them back in?
