one of my speakers started cutting out at any volume and seemingly randomly. I discovered that by tapping the woofer cone it would come back on and work perfectly until it didn't. I was told that one of the leads to voice coil was detached. I thought I could fix it.

I cut the dust cap off (carefully) and found that, of course I couldn't even find the wires so I decided to get replacement drivers. Confident I was on the right track.

I replaced the drive and surprise! - same problem.

Can anyone tell me what the heck is going on and how can I fix it?

If the whole speaker goes silent, failing contact in the safety (thermo-) relay.
Give it a blast of contact cleaner and excersize it a couple dozen times.

Do you mean the built-in protection circuit cut off switch on the front of the speaker?  (I was wondering about that...)

Thanks,

No.
The small thermo relay has a yellow reset button sticking out the front near the "Overload" printing.

Sorry for all the questions----  OK I'll give it a try. Do you think I need to open the speaker and take the reset button out to work on it or can I just spray into the reset button from the front? Sparingly of course...

Thank you sir!

Well, I did what Martin suggested and it work beautifully. For several days. Now same old problem.

Can I just bypass that?  My days of cranking it up that high are long gone.
