Hi,
I bought some wharfedale active diamond speakers cheap ($10) because one side was not working. When I tested the driver it read open circuit. When I tested between the two blobs of solder on the actual cone it read 8 ohms. I thought, awesome, its just a dry solder joint. So I resoldered the terminals to the flexible wires that go to the cone, but it still read open circuit.
Then I touched up the joint on the cone from the flexible wire to the coil windings, but it still measured open circuit. The funny thing was, when I measured from the terminal to the wire it read zero ohms, and when I measured from the wire to the solder blob it read zero ohms. The break was in the middle of one of the flexible copper wires. Yet I could pull on the wire and it was strong. A nonconductive braided uninsulated copper wire? 😕
After I wiggled the wire around a few times it became conductive.
Has anyone had this problem?

No, not personally, but it is a really nice problem! I like things like that. And well "sussed" out too........
What I am hoping for is to pick up some LS3/5a really cheap one day. I am banking on someone throwing them out because they are "small"......
Still we can but dream.

Caleb, solder a very flexible and thin wire directly to the blobs then.
Use a high heat soldering iron, and touch the blobs for a split second to fuse the wire together. If you fail and destroy the cone...you can always salvage parts from the speaker - especially the active circuitry/amplifier. For $10, the risks are well worth it.
Enjoy~

I'm quite happy with these speakers now actually, for $10.
Working beautifully.
Active speakers are so convenient. So much less wiring, connectors etc, just plug them into anything.
