Speaker Repair

Hey all - any help would be much appreciated. I recently found a pair of 15" yamaha speakers (8 ohm, 500 watt) outside my practice space (people are constantly throwing away partially working items).

Anyway, each speaker has the same problem: The woofer is not passing signal.

Before buying a replacement woofer I tried exchanging the speaker with a woofer from a yamaha monitor I already have (8 ohm, 500 watt) to confirm the woofer was the problem.

However, replacing the woofer in the cabinet still did not allow signal to pass. The weird thing though is that I took the woofer from the broken cabinet and installed it into my monitor, and it wouldn't work.

To me this implies that both the woofer and something in the crossover are likely damaged. Would you agree with this conclusion or would you have any thoughts on how I might be able to get the speaker up and working?

You can check the coil for continuity, use the old battery test (yea, yeahhh....), but chances are good that the voice coil is fried and you need a recone. I don't know what the speakers are worth, but Orange County Audio probably has a re-cone kit for you.
