Its so nice seeing a classic speaker breathing new life.

Back in 1982 I bought a set of Acoustical Research speakers, which I always treasured. Had to eventually refoam them. Sound great now.

I built my own speaker boxes about 37 years ago. They each have 1 12" woofer, 2 midrange speakers, and 4 tweeters. But after their old age, each woofers foam ring began to turn to pure dust. For less than $30, I repaired both woofers by replacing the foam rings, and presto bingo, they are as good as new. It's a heck of a lot cheaper than replacing the entire woofers. It took about an hours work per woofer.

I did this to a old set of cv at10s made in 1986. Stored them for almost 10 years because of rotted surrounds. Just couldn't throw them away. Then I found the refoam kits from parts express for around $30. Sound good as new.

Thanks for this. The rolled clear tape as a little handle for installing the new dust cover was a nice tip.

Thanks for this video, I thought I was going to have to replace the whole speakers after my foam failed. I will now do this, thanks again.

Best refoam video I have seen. Many people don't remove the dust cap or shim the voice coil so they get "rub" and distortion. The person who did this Cerwin Vega repair is a craftsman! Thanks

It is so worth learning to do this yourself.. Especially on Cerwin Vega's. Great speakers.

I work as a speaker repairer and the CV's are touchy. But experience has taught me to fix speakers without taking the dustcap off. It keeps the look in original condition and costs down. Repair time - 5 minutes.

You can not fix a foam surround in 5 minutes dude. Stop lying.

Yes. That's not quite true. I can't do that all the time - and not all drivers. Only in the summer - when the glues dry fast and I can use glues like sticky-tape. In the summer I can go faster. As repair companies do, we get urgent walk-ins. A pair of cabinets came in that needed 4, 8 inch surrounds replaced. I took the drivers out, did the surrounds and put the drivers back in. And it all worked fine - first time. Repair time - 15 minutes.

I'm pretty sure he meant "minus 5 minutes".

Shimming is optional, I have refoamed several speakers without shimming them, but you must pay more attention in manually aligning the coil around the magnet so that it does not touch it. Cerwin Vega and some other brands are notorious for having a very tight gap between coil and magnet so shimming makes it that much easier.

Did this with my AT-12's several years ago. They're still kicking :)

I love how there's no sound. I'm more focused on whats happening. This is filmed very clearly, great job. keep it up Tuvix72.

Thanks for the video! You save me money and a headache in trying to replace a speaker. And as for the quality of Cerwin Vega speaker, mine are over 20 years old and still bang. And will continue to bang now that I can repair them myself. Thanks again

LOVE my AT 12's.

Nice vid. Brings back memories to see the good old vega agan.

@marcvie9 In order to insert the shims between the coil and magnet, this makes sure the coil is perfectly centered around the magnet. It is an important step, specially with high performance speakers where the gap is very tight.

I used rubber drawer liner sheets for tool box’s ,you have to make your own speaker size templates out of card board into the ring pattern, use tacky glue , don’t need to remove dust cover just center the new cut out ring an start by gluing in small areas let it dry then finish gluing, make sure you clean off old foam rubber real well, this rubber foam sheets last forever an don’t compromise sound quality!!

Yes the Audio of this video may be crappy , but the instructional content is excellent imo . This video is to show you how to do this kind of speaker repair at home etc etc ... This video shows great attention to detail , and shows great quality workmanship !

after 10 years i saw this video...great tutorial how to fix speaker...thank you

I watched a few videos on this subject as I am a do it myself kinda person as well.High quality great job keep up the work...

ive had AR speakers with tweeters, woofers and subs in the bottem for 20 years and the surround and suspension are stil great

This is mind blowing! I thought Dead Woofer - was dead - forever!

I have these same speakers, and thanks to my cats I'm doing this real soon. Nice job

I always wondered how this was done. Thanks for posting.

Great work. You´re a very good teacher!

Your meticulousness is admirable.

We find it's always easier and more accurate to spin the speaker when applying the glues and epoxies, rather than running around by hand and paint brush work. Either way will work if you're diligent.

muy buenos videos instructivos los felicitó y gracias x el aporte

Speaker video with no sound. Lol

8years later Wow you did an awesome job

Foam offers larger excursion of the woofer compared to most other materials. The material is chosen based on the entire design and frequency output of each driver. Foam is good choice for boxed woofers and subs for example, while rubber and stiffer materials are perfect for open woofers such as those used in cars...

Love those Vegas!!

Very nice work, i'm impressed!

Nice work Mr. Handyman!

This is an excellent tutorial for Cerwin-Vega owners for how to fix your woofers, if attacked by foam rot! Any regular glue should work for this.. (School-type seems to be the best pick) Cerwin-Vega is a good quality brand, so think about a better solution than replacing the woofers if attacked by foam rot.. This video proves it! eBay should have repair kits for Cerwin-Vega.. Anyway, the Internet is fairly huge, so it would be easy to find such kits tho ;) Good luck!

The rubber surrounds on the subwoofers is there for strength and is not likely used to tune the resonant frequency of the cone. The light weight foam surrounds are likely used on the higher end drivers to maintain cone mass.

Came back to make sure I do it right today, doing some D2 refoaming.

i am so mad i threw away my speakers, they were just like the ones you fixed here. cool vid

Nice tutorial!

how important is it to remove the dustcap? mine has no visible damage, and my kit didn't include a replacement

Great. you are a real professional. Thx

Cool video and Nice work!! Good luck oute Therese!!

the thing i like most about cerwin vega is the foam :3 and quality ofcoarse

Ottimo lavoro 👍👍👍

Wow that's sweet I didn't know you could buy new foam I tossed many nice speaker's because of bad foam.

Nice work man

very nice work

Amigo, el cubre polvo no es necesario removerlo, pues no afecta a la reparación del Foam e incluso te ahorras material y tiempo.

eBay or Amazon have a good selection

No, but it's the only way to assure precise centering of the coil around the magnet, you can do it without it, just make sure the movement is free before the glue sets.

You could use vacuum cleaner to suck off any possible dust particles from the coil area...

Who ever knew in 9 days would be the WORST DAY in America after this video was uploaded..

You are a master. Thanks.

great video. I read I can use Elmer's wood glue. Is that correct? If not what glue do you recommend?

@BassPounderX It's normal with age, it's called "foam rot". Best thing to happen to good old speakers, they sell cheap on the used market and you can repair them for little money :-)

Found a pair of CV e-312 sitting on the curb. Near mint except for the foam.

nicely done.

Hi, what type of glue are you using? Excellent vid, thank you

Speaker exchange out of Florida. If you haven't purchased already. They are knowledgeable and reasonable.

Nice video. Thanks.

@tuvix72 you should be using plasticized(spelling?) ca glue for surround and dustcap. you can use regular ca glue for the spider assembly.

Looks good

Ottimo video, mostra passo-passo, la giusta tecnica per riparare un woofer, (sostituzione della sospensione) Magari utilizzando dei collanti specifici ( x foam / metallo / carta) Gli adesivi vinilici in genere vanno bene per il cono in carta, non si utilizzano per "tutto", sul metello in genere vengono utilizzati adesivi epossidici B componente, o adesivi elastici contenenti acetone/acetato di etile, a seconda del tipo di sospensione. Complimenti per il video.

non era necessario assolutamente rimuovere il parapolvere!! Poi , il foam non è originale (quello originale è rosso all'esterno e grigio all'interno). Non ha pulito bene il cono con l'alcool. PESSIMO LAVORO!!!! NON SEGUITE QUESTO VIDEO

@costantinomeloni3353

Quando si ricona un woofer, o viene scollata la sospensione o il centratore/ri , è necessario togliere il para polvere, e spessorare la bobina mobile, in modo calibrato, perchè altrimenti nei woofer sopratutto quelli a lunga escursione, può succedere che a bassi livelli vada tutto ok, mentre ad alti livelli, con la dilatazione termica la bobina o il supporto vadano a raschiare contro il traferro se la bobina non è allineata in modo perfetto. Esistono altri metodi per centrare la bobina, ma il più usato e sicuro è questo. A volte le stesse case produttrici forniscono ricambi ORIGINALI che per ragioni di aggiornamento delle produzioni, possano cambiare colore, ma non differiscono dalle originali a livello di caratteristiche tecniche (anzi). Il cono si, in effetti poteva assere pulito meglio. Tutto sommato, rimango della stessa opinione

i wish u had sound but good vid btw

hey great vid man! I got a older and heavily used JL system from a friend of mine for free when he sold his old car, besides one foam ring being cracked and falling apart, the outside rings around the subs are all shredded and falling apart, so i was wondering if you could tell me what that ring is called so i can buy a new set for my system.

Nice job. I would have touch up the cone a little bit with some Peavy black paint. It would make the look a little cleaner, but really good job there.

at least you can use a black glue to keep the same color of the cone ..... over all ... good job dude

Perfect work. What kind of glue you use?

Which glue can i use for refoam the surround ??? please

Great video

What glue is that and what glue should I use on my speaker

Nice Speaker

Wow, what a small world. The renters we had evicted left a pair of JBL LX500 three way spkrs outside of the unit next to us. I moved them into my workshop room when I found them. He never returned and I have ordered the refoaming kit from a seller on ebay. I will post the vid when I finish.

Would it be better if you use a super glue instead?

good job man

Very good !

1. Fixing things instead of throwing them in the landfill feels good. 2. The foam kit is like $25. I just used it to fix a $400 center speaker.

where did you buy the new organ foam? What about the dust cap? Could you provide website information? Also, excuse my ignorance, but when do you generaly want to do this? When the speaks sound "loose" right? Some of my boombox speakers have a hiss (especially at higher volumes). Not sure what the cause is? Awesome work by the way. Very helpful. I'm into vintage boomboxes and caught between restoring originals or buying speakers that will work that are better quality.

+Mike T A "loose" sounding speaker could mean anything to anyone, it's not a question necessarily of what kind of sound it's making, but where the damage is. A hiss I doubt is coming from the need for a refoam, does the hiss happen all the time when the power is on or when playing certain notes or just when playing/playing loudly? Usually a hiss comes from something electrical, unrelated to the drivers. A refoam is necessary when there is actual damage to the speaker surround, which can be made of hardened cloth, rubber, or foam, and you can buy re"faom"ing kits for all of these, though some sizes are harder to find than others. Another possible explanation for a "hiss" like sound only when playing or playing loudly is if the voice coil is rubbing on the motor assembly, and in theory a recone or refoam could help this but only if the rubbing is because the voice coil is hanging to one side and shimming while reassembling would help realign it, though usually if the voice coil is rubbing the sound isn't described as a "hiss". If you have any other questions feel free to ask.

It´s necesary to keep cut out dust cap , ???? Thank you!.... beatifull hands!!!!♥

I wish there was sound in the video but good video, awesome.

Music? no sound?

Very good video

Awesome video, great help! ... saved me money, better for the environment... take something old and fix it... and actually learn how to do something.

WOW!! very good.

this is just fun to watch

Just bought a pair of Duntech tower speakers from Australia yesterday. They were 10 Gs when the came out in the 80s,I got them for 1,300 . Anyhow after playing a few records very loud the surrounds went,all 4 of them. Im just wondering if I should do this myself or get an experienced repair person to do them. I cant even find a place in town that sells the surrounds,and Im wondering how important it is to get the original brand for them. Any advice is much appreciated !

The exact dimension of the surround isn't rocket science, get as close as you can, probably a bit larger OD or smaller ID if you can't find an exact replacement size. Doing them yourself will be the same as any brand speaker, take your time, be sure you get the VC centered before letting the glue set on the last step. If you can push in & out at the center of the cone and not hear any light scrunching noise (of the VC hitting anything) of any kind, you're good. That's why they cut off the cap and use the shims as it's pretty foolproof. Others leave the cap on and just adjust the centering as needed until sure the VC isn't hitting anything.

The dust cap keeps dust and crap from getting between the voice coil and the walls of the magnet, which causes scraping and stuff.

oigan pero poruqe le abrio en el centro y lo sello otra vez... que yo alla visto ¡no le hizo algun cambio mas que en las orillas?

The kit is about $35 on eBay

Cerwin Vega very nice taste.

those speakers kick.

Couple of questions to the poster: First, do you prefer this kind of glue over the more clear cement type? Secondly, I always wondered... is there any material, paint or anything that can be used to re-blacken old stained paper cones that won't affect the quality of the sound in any way?

You did a very good job. Appreciated!!!!

porque rompes el guardapolvo? el guardapolvo se puede quitar y poner sin problemas si utilizas otra técnica. Saludos! !!

Cual es la otra técnica amigo

I like the red surround.

I really enjoy Klipsch home audio. What's your take on them?

Shim the coil with THREE shims/spacers 120* apart.. You'll get better centering, and use enough thickness to lock the MMs in it's home position while doing this. Use an air compressor to keep everything completely clean. Cleanliness is next to Godliness when doing loudspeaker work. Hope this helps-Good video tho- Jason/PMR

I blew up both my kicker comps fried em i'd like to know where to buy new cones for cheap

Is it necessary to replace the dust cap if it is not broken?

If you're handy and dealing with good speakers, this is far cheaper and only takes an afternoon to complete.

Hello bro..how i can get the rubber and the dust cap??

Ever since I replaced the foam on my AT-12's the speakers no longer flex, even at high volumes. Is this just because of the new material used in making the foam?
