Speaker grilles go on when nephews come to visit. Sound quality marginally worse but mental health young lives and family peace maintained:-)

I remember my grandaughter coming into the living room the first time after I had removed the grills , she went straight to the midrange dome, finger extended to poke it ... I shouted no just in time .. its amazing how they spot them and are drawn :-)

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'm a teen now and I'm actually looking this up to repair tweeters i dented when I was 4

I was working in a HiFi shop when a family came in one Saturday and a little 3yr old ran down a line of about 20 floorstanders on display popping in every tweeter in about 30sec with their finger whilst we watched it happen as if in slow motion, none of the staff could react quick enough! The family were a lovely bunch and no harm done. I spent the rest of the morning carefully popping tweeters out and ordering spares 😬

I work in a music store and run into this issue ALL THE TIME. I have found that Gaff tape works the best for this purpose. it's adhesive is just strong enough to pull out even the most collapsed tweeter domes/dustcaps with no damage or tearing.

"Whipped to DEATH" LOL! Don't do it! It's so tempting for kids to "poke" at speakers. My son is 24, but I STILL leave my grills on just in case. My M. A. Silver 300's weren't cheap! Love your videos, Paul. Thanks!

Cheers for this... i was gonna buy more speakers! I used the tape method & it worked ok.. didn’t get all the small dents out but better than nothing! 👍

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 my dented tweeter pop back out years ago, but I've been living with this terrible feeling that my tweeter is irreversebly damaged since then. Paul, what a relief after so may years of insecurity! Thank you!

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've been waiting a long time for someone to answer this question. Thank you.

Thank you thank you thank you! I dented a tweeter getting some studio monitors out of the box! I was thinking "oh god i've ruined them and i haven't even used them yet". But all sorted with some strong double-sided-stick-tape. Thank you!

Great video post Sir!!! I've been doing that very simple technique for tweeters. love your candor as well. like listening to a Dad I never had. God bless you and your family.

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!

Enjoyed your thoughts on tweeters, pets and children, always appreciate your POV. Thanks!

I knew I was going to face this problem. One of the many reasons I love my kef's. They have the cage over the coaxial array

Accidentally dented a Monacor DT-352NF during testing. Metal dome tweeter. Dent was about 10mmx10mm. This introduced 10-20% distortion spikes (measured on REW) from 6k to 18k as compared to previous measurements.

Our cat Elvis The Pelvis shredded the Emit tweeters on my old Infinity RS5000s. Cat claws are the perfect instrument to get between the slots in the metal plate on top. I bought new Emit ribbons from a NZ service agent and they were dead easy to install. Elvis was buried under our lemon tree, but some years after this indiscretion 😹

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.

I use a vaccum cleaner for dust caps. place the pipe on the dust cap, turn on vacuum, it pops out, turn the vacuum off before pulling the pipe away because it might pull the cone out too far and that's it.

I was a professionell child. I poked a pen through a 15" and a mid range. Good thing the towers were so high I couldn't reach the tweeters. Now with a repaired 15" they play in my room. I will build metal cages when that time comes around. For the kids of course, I would never block the sound.

Paul - Thanks for this video. I was able to get a silk dome tweeter pulled back out with duct tape! I'd tried some other tapes but I appreciate so much your help. All good here!

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.

I've seen accounts online that denting can matter with certain metallic materials. Creases cause stress hot spots, and the regular operation of the speaker can then induce metal fatigue to the point of failure. I've only seen this with regards to full range titanium cone speakers, however.

I had it with a KEF tweeter. The sound was still good but it looked weird. I took my vacuum cleaner and had it put in the LOWEST power setting and gently pulled it. Worked great! 👏👏👏

If the tweeter is totally pushed in, engrave Focal on it, and sell it for one thousand dollars : )

One of my kevlar dome tweeters got pushed in by my neighbor, it popped right back out and works just fine, but it is so annoying dealing with stupid people.

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

I had 2 pair of Quad ESL57's in a stack when my first kid was born. First thing I did was sell them. 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.

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.

Thanks a bunch... the tape happened to do the trick and my OCD issue is gone...

If your kids poke at your speakers, just poke them back!

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.

Solved my problem w my BW 603! Thanks! Now where’s my bullwhip! :)

And 5 years leater i just fix my new jbl 52 tweetr, Thanks Paul

Many years ago one of my DynAudio D28 tweeters got dented in. I looked at it for a few days and then decided a little negative pressure might work. I placed my mouth on the tweeters metal plate and sucked to form a vacuum, when I backed off the dent was gone and there were just a couple of wrinkle marks on the dome. Had i thought of using tape I would have tried it but my unorthodox method worked just fine.

This is Brian. I really wish you would have explained to people that on larger woofers and midrange speakers, these domes have no practical purpose except as dust covers. As a matter of fact, were you to manufacture speakers, this part is called The Dust Cover. I've seen speakers that have no dust cover, be it because the glue wore out or they were very old and the dust cover wasn't installed at all. It actually protects the windings from gathering dust.

From what i JUST heard it rattles not too bad but it can get irritating but I've been pushing it back 4 awhile maybe it's the wrinkles idk

No tape I had in the house worked but my son in law-to be was trying to pull the dent out it out with a Vacu Vin wine saver vacuum hand held pump. It did not work until we added the rubber stopper against the dent to make a better seal...voila!!!

I have be building speakers for over 50 years and in that time I have also repair quite a few. I have used a vacuum cleaner hose to suck the deformation right out. Be careful not to allow lengthy suction.

"Child has been sufficiently whipped to death" LOL That's probably the funniest thing I've heard you said in all your videos

Used scotch tape on my soft dome tweeter on tannoy reveal actives and popped right out. Gotta watch my nephew on family visits! Cheers for the tip!

Thanks for the tip. It worked beautifully on my psb.

I once got a dented dust cap on a cardboard subwoofer cone, obviously doesn’t affect the sound but it’s a lot more difficult to pop back out. If this happens to you, you can use a sewing needle to pull it back into shape.

My friend used to work at a Hi Fi store, and they had a tool for getting dents out of domes. It was a long time ago, and I can't remember exactly what it was, but it was repurposed from something used in the electronics industry, and worked by suction (it was not a solder sucker). Anyway, it was someone's job at the end of the day to go around and suck all the domes back out after they had all been pushed in by kids throughout the day. He said Saturdays were the worst - every single dome in the store would be dented without fail.

this helped, the cotton swap technique.. thankyou so much

What a pleasant person! :-) And a hopeful answer! Thank you

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.

Audio, Automotive, music, metallurgy, firearms have always been high on my list of things of interest. I've always regretted not being able to build speakers. To Be able to understand how they work along with being able to build them. Because time and money never permitted.

I liked this just because you said "whip you children to death" , lol. No please don't do this to your children it's meant tongue in cheek!

1999, 21 years old, I was still living at home. I had just purchased a brand new pair of B&W 601-2 👍. The day I bought them, happened to be the same day my mother was taking care of my 7 year old cousin. The speakers had been set up for approx 2 hours. I made the fatal error of leaving the grills off. I had to pop out. I shut my bedroom door. Came home, door wide open 🤔 to my shock and anger, one of the metal dome tweeters was not a dome anymore 😡 I was furious, my mothers response to it, "it's only a speaker, she didnt mean it" my response WHAT!!!!! Had to take speaker back to the shop same afternoon. Now the naughty bit. Money abit tight back then, already spent my budget buying the speakers. I managed to convince the shop owner they came to me damaged 🤥 he excepted my story and repaired them for free. I still feel guilty to this day. And yep, I still own the speakers.

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.

That tip worked a treat!

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.

I got a 2" softdome midrange that was dented when delivered. I just carefully sucked it out without getting it wet. Immediately after I could see 5 slight indentations in the semi gloss finish. In a couple of days I couldn't see a trace. I couldn't measure distortion from it and was the same as the other 3 undented and perfect domes I got.

Thanks Paul for the good suggestions about the remedy and reaction on the kids which are in fact exactly what I have been doing!

This helped! Thank you! 👍🏻😊👍🏻

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.👍

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.

The tape trick worked for me, both of my Rega R9's had dented tweeter's (the ones in the center) and rolling tape over both drivers popped em back out.

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 🔊

Double sided tape.... Works great. 90% of my highs were gone, both tweeters. Until this idea hit me. Pushed firm, pulled very slowly popped em' both out. Sounds like before.

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.

It's not too difficult to find some cardboard tube just the right size, attach your vacuum cleaner, and VERY gently start it at its lowest setting. I've fixed quite a few this way.

Excellent Thanks

I got the B&W CM s2 speakers..unlike the 1st series they covered the tweeter with a metal mesh grill so no more problems. Best part is that for those who don't have this issue..the grill can be screwed off.

dust-cap on woofer can sometimes be pulled out with a vacuum cleaner (preferably one you can adjust the power on)

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.

Please can anyone enlighten me as to what tower speakers those are in the video? The midbass/bass drivers look identical to the ones on my Sansui speakers.

What if its torm

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

I came for dent fix info, I stayed for the life lessons.

my buddy and I would practice juggling ( harder than tennis balls ) and other such - I ran guitar string wires across the front of all the speakers from the attachment screws. speakers saved.

I have repaired varios light dented dustcap with suction. I worked before with a different tweeters (cheap Chinese Twitters ) with metal "titanium" diaphragm. those with metal chassis and phaseplug, the diaphragm are almost re formed by hand and a popsicle wooden stick, And some modifications after, i achieved the right sound.

Also for collaped dustcaps, use the vacuum extension tool, suck it back out.

What happens to b&w diamond tweeter if handled hard ?

The metal dome tweeters on my Kef speakers got dented and it made them sound as though the singer was singing with their nose pinched. Never mind kids, I lived with 2 women approaching middle age then and "it definately wasn't them who had done it"

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 ...

I tried the tape method and i worked great. Thank you for the idea

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.

Thank you! This little trick saved my vintage KLH tweeters!

I’ve got a pair of Alesis monitor ones that are 4x older than my toddler. It’s easy enough to take apart the driver and pop it back from the inside. Annoying but it works fine.

Pull it out with a shop vac? Doh!

My recommend trick is getting a toilet roll tube, put it over the caved in tweeter and suck on the other end . It should be enough to pull it back into shape. DON'T USE THE VACUUM CLEANER!

I was one of those victims when I was 8 😂 totally regret it now

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.

That seems like a genuine dude!

I've lost count of the subwoofer domes I've used a vacuum to undent ;)

I have JBL 2121 10" midrange drivers in my loudspeakers. These drivers come with a concave dustcap. After decades of use, the surrounds had to be replaced. 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!

The sound was slightly muffled. My ears heard the difference before my eyes discovered the dented tweeter. And... I used the suction from my vacuum cleaner with a small vacuum cleaner attachment to undent my dented tweeter.

I’m an aspiring audiophile, but it’s so satisfying to press those little domes in! Please help!

Would there be a difference in sound of the woofer if the dust cap is broken? Or maybe without a dust cap?

I have used a vacuum cleaner with some tape around the edge of the end of the hose to great success on several occasions.

I did this a few weeks ago. A total eureka moment! Paul. love the videos they're insanely interesting. If you're ever in Ireland! The Guinness is on me!
