I have some used ones if you can't find a new one ...but new or used their life span is not the best and varies ..probably due to humidity levels of its environment ..bc im sure the piece of paper or what ever it is inside for the speaker inside ...was not made for longevity LOL
The major problem with them is the foam spacer in the speaker/transducer deteriorates and collapses causing the metal plate to contact the electromagnet. This keeps the metal plate from vibrating so you get very little or no sound out of it.
I can't remember if it was you mikestertwo but I had asked how to test them ... on the thread NOKA72 started that was lost .. so here are pics of the wires going to one ... appreciate if anyone knows which ones I need for hot and ground .. thx
They are repairable, CzyKats44 posted a thread on how to repair them. I had saved the thread, but not knowing that the pictures were hosted on photobomb they didn't save. And can no longer get to them.
Note that it did have to do with the foam deteriorating.
