    The glass fuses may actually be lamps. I have seen some crossovers (MB Quart) where they use a lamp in series with the tweeter for protection by dissipating excess power.

    The resistor appears to be a little toasted.

    Joemex makes circuit breakers and polyswitches. I think you are looking at a 1A-50V polyswitch. That resistor or (inductor) is indeed overheated. Those glass tubes are lamps. The coil is an air core inductor. Perhaps you could get a value off the other speker's XO for that over heated part.

    Is this the speaker? http://www.sanfranciscoaudio.com/PageMill_Images/Buddhist-Marin/MVC-068F.JPG
