Sorry to hear of your loss.
I made a boo boo a few weeks ago. I was trying to figure out why I did not have sound after changing around some interconnects. I had left the volume open on a preamp and changed sources, bone head move. At first I wasn't sure I damaged the speakers but after listening it was apparent something it had lost its magic. It ended up being a damaged Synergystic Blue midrange fuse not the speaker. Now I turn everything off everytime. Hopefully lesson learned.
