Did someone poke in the center of your speaker? CNET's Donald Bell shows you how to take the dents out of a damaged speaker dust cap.
I needed this video about 15 years ago!!
Yes.
nah bruh i need this rn
I'm drunk, got keen on restoring 2 speakers myself and my housemate own , the vacuum worked a treat, it's a good method even a drunk can use
Good luck kings and queens
It is not very wise advising people to poke a hole on their expensive speaker using any kind of pin or worst is the paper clip. Never poke any hole on your speaker since sound does travel with such force and eventually it will tear out the hole.
PLEASE FOR PETE'S sake, use a piece of duct tape or any kind of sticky tape. Layover the dented area, use your thumb to gently push the tape to make sure it cover the whole entire dented area. Don't worry if you use a little bit of force since the cone was dented inward already anyway. Now use your both hand lift both ends of the tape at the same time. Voila! The stubborn cone should be back to its normal condition. (There might be some very-hard-to-notice- line marks if the cone was left dented for so long).
IF NOT, REPLACE ANOTHER PIECE OF TAPE MAKE SURE YOU DON't fingerprint it on the sticky side.
And PLEASE DO THIS FOR THE SAKE OF YOUR BEAUTIFUL SPEAKER.
NOTE: In case there might be some glue or adhesive left on the cone surface, you may use warm water or finger nail polish remover gently remove it with a Qtip.
Worked perfectly, thanks man.
+Tịnh Như Không THANK YOU THANK YOU THANK YOU!!!
lol I was thinking the same for certain methods... I just created the hands down best way to fix this if you look in my channel you will see it I don't want to spam with links.
Thanks, saved my speaker!
does it work on a plastic one?
Brill video, you inspired an idea in me which fixed it. I found a 3ft tall 600w speaker on beach (believe it or not lol) - it was completely concave but works ace. Had it months and months and just wandered if I could make it convex again so found your vid, after watching I tried using my home dentistry kit (long utensil with little curved hooks on. Piereced centre and it worked perfectly. Thanks for inspiration, hope our ideas helps someone :)
Was beginning to wonder if there was any value to watching videos all day, every day...then BANG! This tip is like winning the lottery.
I just did the vacuum trick, but I made the OK sign with my hand and held the hose up to the hand. This way I was able to reduce contact with the speaker cone and spread my digits to reduce suction. It worked perfectly and nothing but my hand touched the cone. Either way, great video...many thanks. Now I can let my kids live another day (evil minions who feel the need to destroy my stereo, car, motorcycle, or anything that I covet...lucky for them they're cute).
Alex M Alex M when he first pulled out the paper towel tube i was thinking along those lines of having something to easily manipulate the suction with. I was thinking something shorter like a toilet paper roll or cutting down the paper towel (probably less grosss) but I think your finger idea is much better! Great idea! 👌
sounds a little racist
@@stephen32frazier huh? I don't get your comment
Haha darn straight! Evolution knew it had to make em cute to survive 🤣
Had it been my kids, I'd have dropped them off at the orphanage.
Thank you for your help you save my life from being a living nightmare. I accidentally damaged someone's speakers in their house and they left me alone for a few hours. No I don't need a falling out with somebody over damaged speakers.
"I'll let you use your imagination on that one" LOL XD
Use Electrical Tape - Pops right out!
God bless you 🙏😇 just did it and it pops up
How is electrical tape sticky enough ?
@@jc1608 Duct tape is better by far.
Duct tape is the way to go!
I'm about to try it with gaff tape
I have some old but great looking pioneer speakers that I popped in when I was like 5, now I'm 18 trying to fix them LOL
just tried the vacuum cleaner method on a car speaker... worked like magic... THANK YOU !
Thank you sooooo much!!! My 7yr dented mine in. Was going to use speakers for his online schooling. Thanks!!
Thank you,
"Q tip" method worked flawlessly, after trying all others.
Thanks a lot! I used the vacuum method and it worked perfectly!
Thanks a tonne! The vacuum cleaner worked like a charm!
the hoover worked for me, thanx a lot.
I would recommend you do the vacuum method first and use something like a bottle to make the suction better. the qtip is only good for correcting a single dent, so also recommend gluing as many as you have dents and correcting in one go rather than repeating the process separately.
This was a great video! Thanks for the idea. Only instead of the super glue, I used hot glue, and it worked better, and came off easily.
Thank you,
THANK you,
THANK YOU!
You made me so very happy.
Thankyou!! I have an vintage akai stereo system made in Japan, all original. My brothers friend pushed them in nearly 20 years ago and I have been meaning to fix them for years 😅
First tip worked for my KRK Rokit6 using a Dyson vacuum! Many thanks!
Great! The hoover technique saved my life today! ;)
Man you are a life saver.. my friend told me use pin but my problem was damageing small holes.
Tx for last tip.
if you use a fine sharp bent needle, the holes will be tiny and easy to plug with dots of cheap white paper glue, which will dry transparent. Just take your time and be a little careful with the entry
Thank you! Never thought I'll find an answer to my question, right here, waiting for me 8 years after, internet have all the answers 😆
I just used the giant straw method, it WORKS !!!
Thanks !
thanx. vacuum cleaner worked perfect! now I can go on listening to my HiFi speakers on sansui g6000 :)
thanks so much! Paper towel move worked perfect for me.
Just fished out an empty paper towel holder from the bin and fixed the cover within five minutes of the dent happening, great tip!
vacuum worked great! Used a roll of masking tape as a outer frame and covered it with my hand and the hose.. Thanks!
YOU ARE A GENIUS LOL THE Q TIP WORKED VERY WELL
The vacuum truck worked, thank you so so much!! 😊
very, very carefully use the vacuum. set to lowest power.
Worked for me.
I have m-audio bx8's and the tweeters are small and soft ones so I just went to the bathroom and got a toilet paper roll and worked wonders!
Thx used the Q tip method worked a treat
Just tried the vacuume hose one it worked perfectly great
these 'how to do it' videos are really helpful 9y)
Thanks man I tried both of the the last two methods on two of my speaker domes but on the one with the hole a size of a needle everyone noticed it;D
I have recently acquired some speakers with a 16" (? exact) woofer and a 5" or 6 " midrange. (The're on a high shelf now and I forgot the exact size.) On one of them the woofer and the midrange were dented. The woofer responded immediately to my shopvac with no marks or dents afterward. The midrange was stubborn. I tried the q-tip, it kept pulling off. The paper clip worked. A little super glue sealed the hole. They are working great now.
Yeah, I don't like the q-tip trick much. This guy doesn't explain the fact that there are thousands of Speaker makers who use different materials. Some of those materials do not react well to the chemicals in super glue. In the future, those holes can be plugged with cheap paper glue that dries transparent. Just use the tip of the sharp needle or toothpick as the applicator.
just use a piece of sticky tape, lay it over the cone and gentle pull... then repeat as required! I did this today and it worked like a charm on one of my old celestion speakers :)
yes because they sound amazing and have excellent soundstage
Thanks man I used that poking thing and it worked
Thanks I used the vacuum it worked after a few try’s
Tried a car vac and electrical tape. No luck. Brought out the duct tape and it popped out on the first attempt. Thanks!
Used a suction cup made for removing mobile screens. Worked great for 8" speakers with "plastic" type cones
There is a fifth way: you can use masking tape and tape the dent center leaving several inches of extra tape at both ends. Then lift both ends of the tape And the dent may come out. Last time I did this was about 50 years ago. Duct tape did not exist at that time but I bet it would work even better.
just did this with gaffer's tape and it worked perfectly. sticks well and removes perfectly clean. duct tape would probably work just as well but might carry some small risk of damage or residue
Duct Tape dates back to WW2 or poss earlier
adding a new cheap dustcap over the old dustcap is very simple
Any idea on how to remove the slightest bit superglue off spearker now ? Also it worked flawlessly just got a tiny bit of glue left on it
What should I use I have a small peel were the rubber part meets the plastic cone of a midrange is very small but I don't want to get worst I don't know maby some silicon?
The Q-tip method worked very nicely! Thanks!
Worked👌🏼 thanks
Does it matter if it's pushed in? Besides looks, Dose its effect the sound?
The vacuum worked great for me!
DUCT TAPE WORK FOR ME
If you use the "superglue/Q-Tip" method, 2-3 drops of nail polish remover (the acetone kind - not the other citrus-based kind) on the Q-Tip will release the superglue and is a much better option than the twist-'n-pull method of Q-Tip removal.
I used my vacuum cleaner with the funnel from a new small plastic petrol can on the end of it, works like a charm... just need to keep little fingers out the studio now. ✌
A vacuum is not a bad choice. If the cap comes off, reshape it and use some paper white glue around the rim and drop it back in. Make sure to put a tiny weight on top of the cap when gluing. A couple stacked quarters does the trick. However, some dust caps are designed breathe and that can make it difficult to use a vacuum. The bent needle is usually the best trick. Dont worry about holes. You can plug the hole later with a dot of white paper glue applied by needle tip or toothpick, which mostly dries transparent. The problem with the q-tip/crazy glue trick is that some speakers have glossy tops dust caps or some kind of finish on the top. Basically, surface that doesn't react well to the chemicals in your crazy glue.
THANKYOU DONALD BELL!
very useful friend thanks!
I still have a dent in my subwoofer cone... any other tips?
Try heating the cone with a hairdryer for a minute or so to soften it before doing the vacuum trick. Worked on the cone of my krk rockit 6. Its a better option then poking a hole in it or applying super glue.
That's actually not a good idea. Not all cones react well to heat and warping your cone is a great way of introducing buzzes and distortion. If it's a very old paper cone, it might already be pretty dry and near time for a refreshing. If you can't use a vacuum, then the bent sharp needle is the best trick. You can plug the holes later with dots of cheap white paper glue that dries transparent.
Great video! Thanks!
Thanks for the last great tip.
Thanks the cue tip worked
awesome!!! it really works
I tried the Q-Tip superglue trick on the much smaller dome of a four inch speaker and it wasn't worth it. It didn't work. Out of frustration, I used a pin that I reshaped into a curve. With the pin inserted, I was able to repair the dome into its original shape without any problem. The pinhole it created wasn't a problem either. Since I already had the superglue on hand, I used that to cover the hole, and while I was at it, gave the dome a thin coat of superglue to help the dome keep its shape. The coat of superglue did not have any effect on the sound of the speaker, whatsoever.
will this work on a jbl aluminum cone?
Pardon my ignorance on speaker basics - would like a tiny direction for my problem. I bought a 8inch 50 watt woofer (not sub woofer) about 15 years back, used it for few hours and it sounded good. I opened it today and connected it to my amplifier and it outputs too little volume. I gently pushed the cone and spider up, and the volume goes up and it vibrates well. How can I fix it? The spider feels hard... the soft rubber on the outer edge of the cone is soft/flexible...
One possibility is a leadwire issue. Another issue could be coil alignment. If the sound has some crackles while playing, it's probably a lead wire issue.
Vacum did it for me! :-D Thanx
One way to reduce the chance of excessive suction pulling the dust cap off with a vacuum, is to place the vacuum nozzle as close to the cone as possible before turning on the vacuum.
When the cone pops out to normal position, don't pull the vacuum way while it's still on. Turn off the vacuum, then pull the nozzle away.
scrolled down the comments after i commented and same solution that works great.
The speaker cap is for protection only. It is not the speaker. Having a pin hole in the cap will not change the sound... nor does a dent. Fixing a dented cap is for cosmetic purposes. If you keep your grills on, you don't need to do this. If you decide to sell the speaker you might do this because appearance will effect selling price.
That depends on the speaker. For most Woofers, yes. However, some woofers are not ported which means the designer intends on the cap to aid in providing back pressure against the coil/cone assembly movement.
Don't make hole on dust cap because it will start some noises while playing. Use vacuum or tape or something adhesive like chewing gum.
True.. i didnt read this comment before attempting to do it... Now i have a hole in my speakers.. i fixed it uaing duct tape colored black
Making small holes are fine. The vacuum and bent needle trick is how we pro-reconers fix your dented dust caps, or we remove the cap, reshape it and glue it back down. We don't really use the super glue trick as some manufacturers use materials that don't react well to the chemicals in Super glue. Tape is good but also can be a problem with the materials of certain caps. Small holes can be filled with cheap white paper glue. Just make sure you flip the speaker cab on its back so the driver faces up and gravity is working in your favor. Use the tip of the needle or a toothpick as the applicator, and simply fine dot the holes. When the white glue dries, it will be transparent. The hole is filled.
Worked a treat
For Better Results. Use 3M Double Sided Tape (Use 3M not any Brand since its more sticky)
you have to stick 1 to your finger and the other to the speaker cap thing. if the Sticky part wears out. get another one. do it over and over again until its fixed
Nail Polish remover works well to remove super glue.
its works for me thanks
match stick works better than a Q-tip but it may take more tries although there is less risk of ripping the cone or leaving behind residue
How do you get the tape to stick? You can't press it into the dome.
Thank you very much
We all break it open, what a genius on this stick-and-pull idea.
I tried scotch/electrical tape on my tweeter, did the job.
Sorry no poking holes in caps ! a shop vac will generally do the job on larger caps. With small plastic tweeter caps I use Gorilla tape folded over a pencil eraser. gently push it on the cap with a quick pull it will pop out. Gorilla tape has a stronger adhesive than masking tape. the key is not to touch the tape on the area being used on the cap, oil from your fingers makes the adhesive less sticky.
Thank you so much 😊
They still make paper dome dust caps?
1:33 Five to ten minutes? The only super glue i've ever seen dries in five seconds.
This video saved me $400 for another ATMOS speaker pair. Thanks! Kid put a toy elephant into the speaker cone, then put the dust cover over it and crushed the cone center, now its all good! Woohoo!
vacuum cleaner wins! fast, no hole. Thank You.
Bro life saver
Love inverted dust caps or no caps at all.
Good Idea. Thankyou +
I had some heavy duty JBL K110's that had been abused beyond belief but I used a glue gun and glued a glue stick to the center like 10 times to get out but it still had lots of wrinkles but better than before.
vacuum only did the trick for me just be careful with it, don't go full power on your first attempt
thanks so much
Glue stick. Heat the end with a lighter. Stick and hold. Pull gently. Twist and follow up with isopropyl alcohol to clean residue if necessary.
the paper towel method worked. I was afraid to try the vacuum since I thought it might tear the cone
Thank you
So um like, i have a small little plasma speaker with a dented dome and the dome is only about 2 centimeters... help?
Thank you 🙏
What if the top two speaker in the tower have a metal look to them?
Thanks
If its a silver dome you cold also use Sellotape.
