If I wasn't standing in the room, heard the giant crash, smelled the electrical fire smell, and seen the smoke leaving my B&K 7 channel receiver, I would never believe it! But it happened. Unit turned off, using a monster power reference power center and all. My amp is obviously fried, my center B&W Nautilus HTM1's woofers are welded in one spot. Obvious total loss on those. Good news, I have replacement value insurance and all is covered. My question, for the other 4 B&w speakers, how can I tell if they've been damaged? I heard the crackling from each of them for 15 seconds after the strike. I'd like to take a loss on all for insurance purposes because I'm afraid of the long term issues or other problems that may not be immediately present. What steps would you take and how would you proceed forward? B&W nautilus 805 mains with DS3 rears. I'm open to all suggestions and comments.
