The speaker was originally working fine and I just noticed during my set up in a new house that it was no longer producing sound. I've completely disassembled the speaker for troubleshooting and attached some photographs including the requested front/back photographs of the crossover cup. Below are some additional troubleshooting findings:
• All four drivers are within 4-8 ohm resistance. Each driver was additionally click/pop tested with 1.5 VDC
• every solder joint on the board was probed and tested for continuity and tested good
• every ceramic resistor was tested within printed tolerance.
• All four of the inductors were tested good for continuity
• I have not tested the capacitors yet because they were not bulging and I did not feel like de-soldering all of them to test them individually (yet)
• crossover cup was tested for continuity between the speaker wire posts and the internal spade connectors
One thing I did notice is the blue circuit labeled 2.0K/ 50v tested to only 4 ohms. I am not familiar with this design of circuit, is it a resistor? If so should it be testing 2k ohms, not 4? It also does not seem to have a wattage rating on it if it is in fact a resistor =[
Thank you in advance for any help you can provide!
