While they might technically still be operating, they're certainly in a downward spiral and hard to get a hold of from all the accounts I've heard.
bebop - If you can do some more sleuthing and open the top, we can probably figure out what is wrong with it. First question would be if you had opened the access hatch yet? If the motor is fried, the burnt electronics/glue smell is often pretty obvious. Without the hatch open, you can still push both cones together at the same time and see if they move reasonably freely. You will normally feel a little friction, but they should move in and come back out maybe 1/2" without much trouble. While I wouldn't expect a problem, also check the input plate and make sure there aren't any obvious wiring issues. By chance did you change the speaker cable and not wire it back up correctly?
