Any use for a speaker with fried voice coil?

    Novice question here -

    I had a power tube let go on my Bassman and it took one of my (relatively new) Eminence Basslite 2012's with it. :bawl: I noticed some noise and the speaker failed the push test with some scratching.

    The sealed 2x12 cab is a giant PITA to get into so I just put in a new Basslite and called it a day.

    So now I have this very low time speaker in excellent condition in every aspect except the voice coil. Is there any practical use for the speaker or parts? Does one repair a voice coil? Or do I just toss it and move on?

  3. Yup - Recone, or use it as a really heavy duty refrigerator door magnet.

    Yes indeed - ignorance will get you every time.

    I didn't realize that a re-cone addressed voice coil issues as well as torn cones etc. :bag:

    Thanks for the responses. Time to look into a re-cone.

    There's also quite a chance that the other dirver is also damaged, maybe not to the point of rubbing, but if one went out, the other may be close. It wouldn't hurt to get it looked at. I would also be surprised if a tube amp took out a speaker but didn't have harm to it's own output transformer. If the speakers were wired in parallel, then the amp might have seen 2x the impedance when one driver blew. Real techs can check things out.

    There is some info on re-coning here in this TB wiki. It shows you what is changed when re-coning.

    The head went straight to the shop for new power tubes and re-biasing and inspection. No damage detected.

    Speakers are wired in parallel but this wasn't a total failure situation. The amp continued to sound normal below somewhere around A on the G string. Then the one driver got a little noisy. This was at the last Cincinnati GTG and I shut the amp down the second I heard the problem happen.

    I'm no expert, but I think that maybe the only speaker problem that can't be rebuilt is when the magnet shifts. I had one do that. My long time speaker guy in Charlotte told my there wasn't anything to do to fix it. :(
