Tom - Thanks for the feedback, I think the crossover must be what is described as point to point.  All of the components are soldered directly together on the back of the board.  I don't see any other possibility than one of the three components has a short.  There is another path but it goes through a resistor, pair of capacitors, and coil in series.  I'm guessing it's some sort of secondary path to deal with some specific problem.  

It's really annoying.  I guess now I bust out the soldering iron, take the components off the board and measure them.  I have a hardware store multimeter that won't measure capacitance.

Jon - your pic shows PC boards which are all too easy to burn.PM sent

Here's a picture of the other side.  While it is on a PC board, there isn't really any significant tracing.  All of the components are connected via solder except one short spot on the left.  That appears to be part of a secondary path to the tweeter that I'm guessing is supposed to carry a very small signal.  It appears the importance of the printed part is mainly to help with assembly.

Forgot to mention serial number 259 and dates on backside of tweeter domes 3/06. (both the original tweeter and the one I bought a few months ago, and written by the same person.)

I see.  Small trace sounds suspect. I've exhausted my clues. I have a PP XO schematic - same drivers, if that might help. Try Rob.
