If I don't need the sound system, I've even gone as far as to face the speakers into the wall, and up against the wall, so nothing can get to the delicate tweeter domes, or even the coil caps on the mid range and woofers. Re-position them only if you need them.

Thanks for resolving this! I had a brief two month stop-over with my parents when I was between houses about 14 years ago, and my mother damaged the tweeter dome on my stereo speakers by vigorously dusting them. It really doesn't just have to be children or dogs! ("Oh, for goodness' sake, the dust can't have been doing them any good either..." She really does think that dust is the biggest evil in the entire world).

Many years ago, when my children were toddlers, I owned a pair of Magnaplaners (sp?) - very high end, but somewhat fragile audiophile speakers. Maggie's don't have domes, but the speaker area is thin and frail, and no match for a toddler with a rubber tip bow and arrow. Knowing my two rambunctious boys, I lived in constant fear that sooner or later, a Tinker Toy would end up being stabbed through my beloved speakers. I confided my problem to a friend who offered to sell me his pair of BullFrog PA speakers. Now, I know that true audiophiles will gag at the suggestion of using PA speakers in place of high end stereo speakers, but to my (tin) ear, they actually sounded pretty darn good. The sale clincher was when my friend demonstrated the child proof (aka drunken dancer proof) feature consisting of steel mesh speaker grills. He actually threw a beer bottle across the room and bounced it off the steel grill. "Let's see you try that with your fancy ass Maggerplanters". Long story short, I sold the Maggie's and bought the Bullfrogs. That was 35 years ago and believe it or not, the Bullfrogs are still proudly displayed in my man cave, still sound great AND have never suffered a dented dome. Possibly a pointless story, but I thought you might be amused.

I would receive many damaged metal tweeters from JBL , INFINITY and other brands . I would use a heat gun at a distance at low setting and fan rapidly across the tweeter , and the air trapped would expand the dome back into place . Please be careful not to melt the surface ! Distance and patience, it actually works very well . A hair dryer would probably be safer to use than a heat gun.

I got a pair of B&W DM601 S2 in exchange for some work I did for a friend. The tweeter domes were dented in. I can’t prove it, but after I gently popped the dents out, the tweeters seemed to be more detailed. The remaining lines and imperfections probably don’t matter, but the larger dents seemed to affect it. I’m talking more than half of the surface area was dented in. Weirdly, this was only noticeable when driven by my dads expensive Quad amp.

I had a dented tweeter once after second hand purchase. Tweeter not clearly visible due to speaker design. I heard and felt something wrong that time. Unpleasant and peaky highs, did some freq test with MIC and found out a peak around 9khz @ 12DB!! And the overall response wasnt flat at all! Removed dust cover and found the dented tweeter! Fixed it by slowly warm It up and roll out the dent from the inside of tweeter moving your finger slowly. Measured afterwards and its flat like the other speaker again which didnt had a dent. So in my case i heard something wrong and to me a Dented Tweeter cant produce the right fequencies at right levels. It took me a while before i heard something wrong. It wasnt a damaged tweeter but a serious dent. Cheers!

patrickalphenaar small. (Shallow) dents won’t cause any problem but if a dent is deep enough so that the cone surface comes into contact with the coil centre when it actuated that can obviously cause distortion. This is less likely to happen with the woofer cone as they have more travel anyway, but with a dome tweeter a relatively small den’t could easily cause issues, especially if the dent is away from the centre of the dome.

To say it has no ill effects seems a little odd to me. A tweeter is essentially a piston that radiates sound waves in a given patter, based on its shape. Once that shape is altered, it can't radiate the way it did when it in its proper dome shape, which is often measurable off-axis. I, personally, would replace any pushed in tweeter, regardless of whether it still sounds good at the listening position.
@tvih842 жыл бұрын
Old video/comment, but... yes, technically the shape is altered, but any little leftover creases after popping it back up make any changes undetectable to human hearing, at least for us mere mortals. In my case even in its pushed-in state there was no audible difference to my ear, so why pay possibly triple-digit sums to replace a minor cosmetic flaw? Which isn't to say that it can't be worth doing for someone else, but for my money it certainly wasn't.
@BadMonkeyFinger_Audio2 жыл бұрын
@@tvih84 Well, sort of...but it's not always like that. What can and does often happen is that off-axis measurements can change significantly, which you could theoretically notice if and when walking around the room while listening. That said, you're right that if you re-shape it and it still works, the difference would most likely be undetectable (I'd STILL want to change it though... because I'm like that! lol). Cheers!

Being excellent parents ( :D ) it was not our children I needed to worry about but a friends mischievous (yet likable) young man of 4 or 5 years old who one day came running into our lounge and (I must say oddly) made a direct beeline for the closest speaker & as he stared at me with a huge gargoyle-esque like grin defiantly jabbed his finger into the pristine shiney dome of a tweeter before I could even think let alone "whisper" ;) the word "NO!!!" Fortunately it wasn't difficult back then, some 15+ years ago, to purchase a replacement locally (I live on an Island in the UK so it was quite unusual to have niche items to hand so I made sure to make the most of it (Sadly the shop has long since closed and a Domino's pizza is in its place...) so I replaced it as it was a metal dome and he did an excellent job of ramming the B&W tweeter near flat & no amount of tape, blu tac or other could restore its position. Anyway a week or so later our friend visited with her mischievous little man & without hesitation he attempted to repeat the act vandalism with equal glee but this time being "practiced" he didn't even take an aiming glance at the tweeter he simply wished to see the pain on my face for the second time, it didn't occur. He lunged his hand forward with outstretched finger expecting a satisfactory "ping/squish" but instead he instantly realised his finger was not pushing anything at all but well & truly stuck firmly up to the 1st knuckle in a metal grill I had purposefully velcroed over both tweeter and woofer. I can't lie, I had a grin very similar to the one he first had, if not identical. :D With a little soap & mummies hugs he was freed, *unharmed, oddly to never attempt such a dastardly deed again. *It was a quality grill bought for the exact purpose of preventing him & other younguns damaging the speakers further & although I had not planned for him to get stuck I was fully conscious of assuring there were no sharp edges, anywhere.

you can absolutely crack metallic tweeter domes when you pop them back out. Ive done it to a set of JBL nd310 floor standers. You can also burn the tweeters out very easily through friction if you dont repair or replace them, and even take crossover components out when they do if you even have a tiny bit of high register clipping coming from an overworked reciever or something.

I had a set of JBL nd310 floorstanding speakers. They had a 3/4" titanium dome tweeter. My ex's kid stuck a finger or pencil eraser end, or something in one of them and dented it. It still functioned fine, but accuracy of imaging on that side of the sound stage suffered a little bit (right channel). Wasn't much at all, and at my current age, i dont know if id notice anything, but the lines of separation were most definitely blurred a little on that channel from then on so to speak. I could detect it with them flipped around as well. I was very accustomed to the sound of that 1 set of speakers, center of image vocals almost felt smeared backwards and up, very subtle and hard to describe even at the time. Once a set of the tweeters popped up on ebay and i replaced them, the "blurred lines" went away. But not before trying to undent yet again and cracking the dome. This tweeter eventually went on to burn out from high frequency clipping way before it should have, taking some crossover components with it (in a half-assed project in some white van special boxes anyway) Funny tid-bit: The way the center image was affected was almost perfectly in line with the tweeter damage. The dent was on the upper right section of the dome only on the speaker i used for the right channel, and the right side of center image felt smeared and blurred subtly "backwards and to the top right" was how i described it at the time. The dent was absurd how small yet deep it was without cracking the dome, and the kid never came clean on how he did it either. It can definitely have an effect if left dented, but even then, it's not very significant (at least on a set of low end jbl towers lol). They still sounded fine for what they were. Those were a surprisingly detailed, and overall pleasing set of speakers being a lower end JBL deal though (I paid like 100 used for the set, were like $500 new or something like that, was my first set of "woah, ive been missing soooo much!" speakers), at the time i was surprised by them to say the least

Even though they have pretty sturdy metal grills in the front and the back, I just could not live with the idea of my kids poking something metal in there. For the ones who don't know the ESL57's, these are electrostatic speakers which carry around 6000V of tension on the panels. Now my daughters are 8 and 10 and a couple of years ago I was able to start all over again with highenderitis. The stack is back, with Gradient subs and 4 Quad II tube amps. My kids know very well how expensive the setup is and treat it with the utmost respect.
@bryede5 жыл бұрын
Although I agree that you probably won't hear the difference, you can measure the altered dispersion of a damaged tweeter. All speakers are designed to act as a piston, but actually flex and "break up" to some degree in a predictable way. If the dome's shape no longer provides this rigidity then flexing will occur where there are creases. So, it becomes a matter of how much it matters to you to restore the speaker's original performance.

Would agree with the minimal effect a dent in a soft dome tweeter has. Duct tape has much better adhesive strength than Tesa or Scotch household tape, the strongest tape I know is for thatching roofs, or rather isolating them, Swiss Siga Sicrall or Rissan, but that might be overkill... as in *kill*. Some amature products available in hardwarestores for the same purpose might just hit the sweet spot in adhesiveness. Maybe try cutting off small ribbons to place in a loop on the rounded end of a srewdriver to get just the little dents, not a large area of the dome. Also, some guy here on KZfaq recommends placing the cardboard tube of a toilet roll around the whole thing to make the dents come out again, using suction with his mouth, never a vacuum.

I've had good luck with the tape method for pushed in dust caps. For really stubborn dust caps, you may have to get more extreme.....I've had some luck with a needle with the tip bent near 90 degrees - pierce a small hole, insert the needle tip and pull the dent out....then apply a small dab of color matched silicone caulk to cover the hole. Metal domes are tougher. The best I've managed to do with a metal dome tweeter is to remove the diaphragm from the magnet and gently push the dome back out from the inside....a pencil eraser can help smooth out the wrinkles, but it's never gonna look like new again, though it can still perform well.

The absolute best way i found to fix collapsed domes is a vacuum cleaner. It works wonderfully. Just carefully put the end tube on the dome and the suction force will pull it back to shape. Works on all sizes (smaller ones even better), I even pulled back huge domes on bass drivers with ease. Careful though not to damage anything else while doing this, also be prepared to do a quick turn of on the vacuum cleaner, if it has sufficient force, not to accidentally rip the dome.

Use Gorilla Tape. I've also used an attachment from a vacuum cleaner but you must keep the suction some distance from the tweeter and approach it very slowly -- it is easy to damage the tweeter with a vacuum. I think significantly dented tweeters do affect sound dispersion and the hardest of these to fix seems to be the Polk trilaminate tweeters. I often see used Polk speakers for sale with dented trilaminate dome tweeters and I believe those tweeters should be replaced.

What also worked for me on woofers is getting the hose of your vacuum cleaner and if you can turn down the power of the vacuum and just suck the dented part of the dustcap out.

I disagree, especially with metal dome tweeters. Once the dome is deformed the voice coil is no longer 100% circular. The tweeter dome is now unbalanced and subject to overheating and rubbing the walls of the speaker magnet. I witness this firsthand with B&W loudspeakers that blew a tweeter shortly after aluminum cone was deformed. Upon magnified inspection of the wire voice coil you could see visible contact points where wire coating was rubbed off from contact with inner magnet. I’m not sure if this is the case with soft dome tweeters though.

Thanks. The tape trick worked on my KRK tweeter.👍
@jeffreywaite22714 жыл бұрын
This is probably not true for most dome tweeters, but my B&W tweeters twist out of their horn mount as an assembly, then you can just unplug the wires, remove the piece that mounts the dome and very gently press the dome back into shape from behind. It may still have some imperfections, but almost as good as new.

I was given a series of speakers by one particular family who wouldn't listen. I even built covers for the last pair and that didn't work. If you have little people don't leave your speakers on the floor without covers. I have a beautiful pair of vintage Pioneer they gave me. Huge. The kids destroyed the Woofers. I've only ever seen a dog do that much damage. 😊 Even if you just have visiting kids PLEASE cover them or put them out of harms way/in a locked room 🔊

I prefer the vacuum cleaner method. Turn on the vacuum and slowly approach the dome with the hose. You may need to keep VERY positive control over the hose to keep it from jamming itself into the tweeter. But eventually, the suction should pull the dome out with minimal damage.

I’ve had at least 50 pair of speakers over the past 30 years and I can say that I have never had a dented tweeter or any other driver for that matter. I have two sons and I taught them from the time they were toddlers to never touch the drivers. I have an indoor cat and he knows to stay away from my speakers. He’s never tried to claw my grills. Messing with my speakers is a good way to get hurt.

Make a cardboard tube using a tube from paper towel. Cut and then tape it air tight so it's the same diameter as your tweeter and suck the dent out. That is how we fix them.

for the really stubborn dome dents, I use a toothpick, dental floss, Exacto razor knife a little Scotch tape and Elmers glue. I take the toothpick and dip it in a small dab of Elmer's glue and make a small dot of glue just off center of the deepest part of the dent and two more micro dabs of glue roughly 120 degrees apart from the first dab. I put these dabs of glue about 1/3 the way down the dip. Then cut 3 pieces of dental floss ~ 1 foot along and with the same toothpick put a small amount of glue on one end of the floss pieces. Then push one end of the floss into the glue and force it into the center of the glue spot. I use a small piece of Scotch tape to hold each piece of the floss on the cabinet of the speaker and NOT on the form. Let it dry overnight and then remove the Scotch tape and start pulling on the floss attached to the deepest part of the dent. As you do, look at where the other two threads are attached and pull on them as you see that particular part of the dent flex. Take your time but usually within 20 seconds, the dent will pop out. Now, take the Exacto Razor knife blade and gently lift the small glue spots off. This usually does NOT take off any of the dome material and works perfectly most of the time. DO NOT put large blobs of glue on the dome; just very small micro dots. Once finished, your dome should look factory fresh with no damage at all, If the dome is cut up initially as if a something was poked through it, you are looking at replacing the dome and that is doable but beyond my simple fix listed here. Good luck

The purist might argue that the shape of the dome is designed to help spread the sound waves evenly across the studio. The sound distribution of a dented cone might not be exactly following that mandate ... I once saw someone carefully cutting egg shells to the right dimensions and glueing them over the "somewhat undented" original domes and painting them, so they could look and perform somewhat like the original - can't quite match the optical effect of pure chromium domes, though, I suppose. Other question: Does anyone have a way to fix the foam rubber rim around the speaker cone? I had a pair of great Lansings once, but after a few years the foam rubber disintegrated and the bass frequencies just short circuited around the edge rather than going through the bass reflex pipe. At first I rushed to the rescue with a big tube of contact glue, fixing the first small tears, but I couldn't quite replace the whole thing with that ...

Years ago I had a pair of DynAudio stand mounted speakers that had silk dome speakers. One of my friends inadvertently pushed one of those domes in collapsing the top of the dome inwards (this was after we both had more than our share of bourbon0. I let it be for the rest of the evening but nothing amiss while we continued to listen to records, The next day I looked at it and on a whim I managed to suck the dent out of the dome by just using my mouth, it just took a second and those speakers sounded just fine for the next dozen years. As to corporal punishment of young children I find the best results can be had by grabbing them by the hell and flailing them against a nearby wall - safely away from any speakers or turntable.

An empty pill bottle with the inside coated in alcohol. Place is over the dome and tilt it enough to light the alcohol then shove it on the dome. It will pull the dome out every time, even if it's one of those made out of aluminum sheet metal which is otherwise impossible to pop back out. That trick can also be used to suck gravel out of wounds if you ever find yourself in such a situation :)

I've actually repaired them with a canister vacuum cleaner. You have to be careful. Don't turn on the vacuum and put the hose end on the tweeter. It will do a lot of damage. What you have to do, is place the hose nozzle against the perimeter of the dome, being careful not to touch the surround. be super careful not to apply any force. then, turn the vacuum on, allowing the suction to vacuum reform the spherical shape of the dome, then, turn the vacuum off, and hold absolutely still, until the motor of the vacuum comes to a stop. Then, pull the nozzle away. It's critical that you keep the nozzle absolutely still, while the vacuum is on, so the voice coil and surround are not damaged. There is no spider like there is in a woofer. If the surround is damaged, and the coil starts to rub, the tweeter could be lost. I was afraid of using adhesive, because the dome was stiff, compared to the very compliant surround. I was successful, but it's a last ditch effort to save the tweeter. the sound quality seemed fine.

I took them to professionals who work on JBL all the time to have them repaired. The service people were unable to acquire original dustcaps, and used convex caps instead. I am unable to hear a difference.

Every speaker you ever see in a retail store has a dented dome. When my wife and I took her parents into our home we also took their Altec Voice of the Theater Speakers with them. These were subjected to a harmful life in a swamp cooled environment. Even during the winter my father in law insisted is running a humidifier in his heater ducts. The result, everything made of wood or paper disintegrated. So by the time my youngest son came along and His Autistic behaviors came with his condition and kicked in the speaker grills, I ended up with the same problem ten times over. I now need to replace both tweeter drivers, as the horns are ok, and the woofers with something that has similar efficiency with the tweeters. And that doesn't look like it's happening anytime soon. Horn drivers are typically rTed in the 100+ db range while thei woofers that are used with them are rated at around 97 db. There's a huge gap in efficiency there. So now I'm thinking about replacing the horn tweeters with a pair of 5 1/4" a ribbon tweeter mounted above a 15" woofer that is as efficient as the other drivers in the system, with the mids and tweeter in a MTM arrangement mounted where the old tweeters horn used to be just above the woofer. Then filling the cabinet with damping material and the walls with damping film to do something to prevent the boxes from booming. I'm aiming for an efficiency of about 90 db accross the board with as flat a response as possible, and then mounting some kind of metal, electrically charged grill to protect the drivers for ever. When the kid try's to kick them in hell learn. Or if the cat try's to make its territory, well.... let's just hope I'm around to capture that on video!
