Unhappy Can I fix a blown speaker?

I just bought these speakers on E-Bay, and they were sold untested and "AS IS". Now, I just hooked them up to test them, and only seem to get sound out of the tweeters. (I don't bear the seller any ill will, it's a pure case of 'buyer beware'.)

This leads me to believe that, somehow, the midrange is gone. Is there a way to fix these, or are they essentially garbage? I looked at the connections, and they look like they wire straight into the cone, but I don't want to ruin anything by trying and making a mistake.

Little help?

Ok, I just looked at the speakers again, and there's a 50V capacitor soldered on one of the power leads... If this is blown, is this a good indication of why the sound is not getting to the midrange?

That capacitor is what filters out the lows for the tweeter, it sounds to me like the coil is cooked in the mid driver.

Ok. Would that be something that is fixable? (Many thanks, in advance, btw.)

IF its only a blown Cap, (not likely) you would have nothing going to the tweet. A damaged cap could become a short, and then you have all the lows going to the tweet, which blows the coil.

If it sounds bad, like scrathy, distorted garbage, it can't be fixed. If it doesn't work at all, use an ohm meter to measure the resistance of the coil.
Sometimes a melted tinsel lead can be replaced, but no, a coil can't be fixed.

Shouldn't we post a BIG warning on the home page of this site that says NEVER buy a USED speaker unless you see and hear it working in person?

I've sold speakers, i'll hook them up and let you listen.

I have a pair of 5-1/4, 3-way eclipse if you need them.

Any speaker can be fixed. Is it worth the money though. That is the question.

Some things you can do to try and diagnose-

As Tom.F.1 said use a multimeter.

You can also push on the cone and listen or feel for a grinding sound or feeling.

Try these two things and post your results.

If they are cheap speakers than dont bother wasting your time. It will probably be cheaper to replace them than to get them fixed.

more then likely the mids have bad solder joints where the coil leads meet the tinsel leads.....

PM me if you want me to help you out
