I have an issue with two 10 drivers out of an AR90. The obvious problem is a voice coil lead became disconnected from one terminal on both drivers (same speaker). It can be reconnected, but it is a bit short.
 

The potentially severe issue is the DC resistance. They never measure over 3.5 ohm. After manually moving the cone, I've seen it drop to zero, OK, .5 ohm to be precise. The voice coil is not rubbing. I checked for a short to the frame and that checked fine.

What the heck is going on and what are my options?
