Thanks, Shelly.
Jin, they're yours. PM me your address and I'll get them out sometime in the next week. Dan has diagnosed the problem correctly, but I'll give you a little background.
First of all, Phil Collins is to blame, so it's hard to tell what can be done. I had invited the owner of a local business in to speak to the patients and he asked to play a friggin' Phil Collins song as some motivational something or another at the start of his speaking thing. I set up the A2s for him in my group room, test everything out, and it's all working just fine with my music. I leave, go about my biz, he does his thing, and at the end someone moved the speakers back to my office. I think "how nice." I plug them in and they start thump thump thumping horridly. Mind you, they are completely turned off, but just plugging in the plug does that. I have no idea what's wrong with them, but they don't work no more.
