Thank you for this. This is the exact fault I had on a 40 year old JVC driver from a 3-way speaker. Was expecting it to be a blown coil but cut off the dust cone and indeed there was a tiny break a few mm away from where the thin wire joins the think one coming through the cone. All soldered up now and just waiting for the glue to dry.

Welcome!

[@peterjosvai9804]

If your language were not good enough, we wouldn't be thanking you for what you have said :) anyway, what you say is very professional.... and your pieces of advice are invaluable, having saved lots of speaker lives, for sure... :) two such pieces of advice did sure save my speaker today :) thanks very much!

[@UltimateDIY]

Thank you! ✌🏼

Wow, i followed your good instruction to repair a car front door speaker. The broken wire was deeper than yours. I first checked the place where the speaker loose wires connect to the bobin/coil wires on the paper face of the cone with the multimeter but the cut was not there. To check deeper i had to cut the little cap like yours which was plastic and that mangled it up. The broken wire was where the cone attaches to the cardboard cylinder that belong to the bobin. There is solidifed black tar like material that is hard like plastic covering the wire around there that made repair very hard. Unfortunately trying to remove that tar, to access the wires i cut into the softer cardboard from te coil that physically attaches the cone. I was not familiar with the anatomy of a speaker, this was my first attempt ever to fix a speaker or i might have tried to dig out the wires from the carboard carefully while preserving most of the carboard. At that point if found electrical continuity and measured 4 ohms impedance. Unfortunately now the coil carboard is cut down to the level of the permanent magnet. To attach it to the cone i would need to glue new cardboard or paper to the cone and to the coil cylinder. You know what i am going to try. The coil slide well i can pull it out enough to provide enough surface to glue new rolled paper against it let that dry then cut the paper at the cone level and glue it there again. Just i don't know what paper and what glue. I'll use superglue. If that works i have plenty of coil wires length since you can easily pull a wire loop it should be fine. ahaha. Funny thing i already bought a replacement new speaker from the car dealer and unfortunately already opened the sealed box so they might not accept a return if i successfully fix the speaker. EDIT: i found that the gap where the coil slides inside the permanent magnet is too narrow to attach more paper to it. I can insert more paper but then it no longer slides freely. I guess that is the end of that attempt.

[@UltimateDIY]

Glad you had a go at it. At least you learned what is in a speaker and in the future you have a chance of saving others. They are quite fragile and require a lot of attention.

[@budgethometheaterandhifi]

Nice work on the repair!

[@UltimateDIY]

Thank you!

[@kpsgenius]

Excellent video, very thorough and very smart 🔥

[@UltimateDIY]

Thank you!

[@vukmartinovic5832]

Hi! I tried fixing my speaker using your technique, but when I removed the cone there were no wires from the coil on the membrane so I can't find the disconnected place. Is that a different type of speaker and do I need to remove the whole membrane just to get to the wires?

[@UltimateDIY]

Hi. Maybe the wires are run on the back of the cone.

[@jamieyeng]

Wow, this needs a pair of gentle hands… I don’t think I can do it but this is an excellent video! I learnt something new today.

[@UltimateDIY]

Glad i could help 👍🏻

Thank you!

[@aot9339]

This is a useful video. Thank you!

[@aot9339]

By the way, how would you fix a 4ohm speaker with no continuity? My plan is to add a bunch of solder in connection terminal and see if that will give continuity, if not, then I'll look for either copper or some other conductive metal plate to replace the current one.

[@UltimateDIY]

Just to be sure I would follow the steps in the video.

[@brigganthewolf1461]

That looks like an Audax WFR-12 or similar. Very nice!

[@UltimateDIY]

Seems really similar to the Audax. But as far as I know, it's a romanian made clone of a Philips model.

Hi, What is in the little cap that you are dipping the solder/iron into?

[@UltimateDIY]

Hi. It's solid flux: www.google.com/search?q=solid+flux&client=ms-android-vf-ro-revc&prmd=isvxn&source=lnms&tbm=isch&sa=X&sqi=2&ved=2ahUKEwjoiKG829nzAhVWQvEDHWuFBXAQ_AUoAXoECAIQAQ&biw=424&bih=786&dpr=2.55#imgrc=JbKSDlOfbUGIYM

@@UltimateDIY Thanks for letting me know. :)

[@WalterDavidRiffmon]

Looks easy.... but not for me haha.. The driver is not available anywhere; out of production. But your video gives me hope that it can be fixed! Maybe I can send it off to have a shop fix it?

[@UltimateDIY]

You can try to send it to a specialised shop.

[@WalterDavidRiffmon]

@@UltimateDIY Thanks. That will be my next coarse of action! I own a set of Panasonic SB-400's which are otherwise perfect!

[@UltimateDIY]

Hope you manage to fix them :)

[@isilder]

I had continuity from thick to thin wire. the thick wire had the break between terminal and cone. The thick wire looked good, but it didnt conduct electricity ???? I soldered a wire to replace the thick wire around the dead bit.

[@UltimateDIY]

Perfect 👍🏻 Yes, speakers are weird like that sometimes. All looks ok, but there is no continuity 🤦🏻‍♂️

[@creekandseminole]

I just recently changed from raw to banana plugs and one speaker works great but the other now doesn't work properly. The audio is barely audible. I switched back to raw for that speaker and now it does the same thing. Before I used banana plugs I was raw for both speakers. The speaker that doesn't work properly right now was always sorta lower audio than the other but now it's almost completely gone. I don't know if it's the speaker itself or my Yamaha CRX-E300.

[@UltimateDIY]

You need to test the speaker on another amp.

[@red2965]

Or just switch speakers outputs to see if it's the amp on the receiver.

[@starmc26]

Check your wiring, switch speakers, and get inside your speaker if all else fails.

[@MyPinkFloydian]

Helped me fix my speaker! Thank you!

[@red2965]

Even your broken English you give good instructions. Thank you very much for your help. Although mine is a newer one so not sure how to do it. Maybe a bit of solder flux make it more better

[@UltimateDIY]

Hope you manage to fix it!

[@kingjer125]

Hi, Thank you I was able to fix and have continuity so the speaker makes sound now but, it is very quiet and when I turn up the volume I get a lot of static noise but no raise in volume. Is this another problem or is it because I have not replaced dust cover yet?

[@UltimateDIY]

Hi. Is the membrane moving freely? It could be stuck.

[@kingjer125]

I pressed the membrane down and it does not feel stuck it is moving, I am getting a bit of rub but thats it@@UltimateDIY

[@UltimateDIY]

Really hard for me to guess without seing myself. I don't like that rubbing tho. If you test a nother speaker it works normally? I want to eliminate wire or amp problems.

[@BTS-fs7bt]

Is it the same procedure for speaker destroyed by loud sound

[@UltimateDIY]

No, sadly in that case it's required to change the voice coil, so basically a speaker rebuild. Your only chance would be the case that the flexible wire broke, then it would be an easier fix replacing that.

[@patrickhall1961]

How do you repair a tear in the speaker

[@ahasiikuyu8001]

I got broken speakers all I did was to make a new aux cable and put it into my pc, but the sound is very low how can I make the sound better

[@UltimateDIY]

Sorry, but it's impossible to guess without seing the setup in person.

[@FriedPawnsForDinner]

I have Bose home speaker connected to my pc via Bluetooth and on my pc it says that its working fine but I don't hear anything from it

[@UltimateDIY]

This requires further troubleshooting.

[@FriedPawnsForDinner]

@@UltimateDIY I trobble shooted and its finally working, thank you =D

[@UltimateDIY]

Glad you got it fixed 👍🏻

[@jrmyzero]

and this is why I like youtube. the fix I did is pretty ghetto, but it did fix the speaker and it sounds fine, so I'm calling it a win, even if there is a half pea sized glob of solder connecting the speaker cone wire to the flexible one; continuity is continuity right? haha

[@UltimateDIY]

Indeed! 😄
