Speaker Repair and Foam Surround Replacement for Cerwin Vega and Others 

10 years later and your video is still helping people. Congrats on a million views.

Used this exact kit to replace my MX-250 12" surrounds. Worked great. Also repaired my 6" Klipsch 4.1 ProMedia sub. Both are working great. Glad I found the site or my ProMedia replacement would've cost a decent amount of money.

what I like about all your videos sir is that all is explain in plain English thanks for doing that good video indeed Regards Juan

Perfect diy vid. This made the repair heaps easier. Thanks !

Can I use mineral spirits on the old glue? 70% alcohol isn’t cutting it and I don’t have any lacquer thinner. Thanks for the informative video!!!

Also, excellent video I just had that question.

This is seriously one of the best "how to" videos ever made.

You sir. Deserve an award for such an astonishing lesson and clear presentation

If you can't explain it simply , you don't understand it well enough.-Albert Einstein It's a refreshing to listen to someone who knows their craft this well. Thank you.

I can hear his passion and love for his work. Well done sir

This is one of the best instructional videos I have ever seen.

Just saved a pair of D2's a church was tossing. I didn't realize there was a whole market for these things! I'm restoring them myself as a project to use in my living room!

This was so simple -- I was hesitant, however after watching your tutorial video, my confidence shot through the roof! I did my first refoaming and it literally went just as easy as your video!!! Thank you very much!!!

I think someone at Pioneer used industrial strength glue on mine. Ended with a hairline crack on one of my cones I had to repair with some Elmer's glue and coffee filter strip cut out for the backside. Other than that the 910's look good again.

I bought a foam kit for two cerwin vega at15's back in 2021. It looked intimidating, so I put it off as long as I could. September 2024. I had no choice but to use the repair kit. It went quite well! Thank you very much for the excellent video and repair kit!

Great video. Going to attempt my first refoaming soon. This video gave me a bit more confidence to try it out. Thanks!

BEST Instruction on YT" Many Thanks 😃

These instructions are clear and strong in every regard. Thanks for taking the time to produce this. I regret having purchased my "kit" elsewhere. A heads up for amateurs such as myself - the glue on the cones on my set were a bit more trouble to remove than in the video. I'm not sure what I should have done differently but the alcohol proved insufficient. Perhaps it was the concentration of 70% rather than 90%. Also the foam overlapping the screw holes can get caught up in the threads and pull/twist the foam.

I was sick when I thought my Cerwin vega 15" speakers died after years of faithful service! It's the only stereo I've seen that I can play loud enough to mix with our drum set! I was even more sick when I saw the replacement costs of these speakers. Thanks to you, I am now overjoyed! I saveD my great system (with your great product and instructions) for the cost of a couple CDs!!! THANK YOU!!!

I been wanting to tackle these woofers for years, but after watching this video...It's gonna happen after 15 years....Cheerz!!!

I can't believe that I waited this long to fix my speakers. They have been bad for years and I often thought that I would love to have them thumping again but was scared to death to do it myself. This was such a great video and a great product. Thank you so much for this! To me, there is nothing like the sound of a Cerwin Vega!

Hey, thanks for the video. I ordered a set of surrounds for my D5s. The whole thing took me about four hours to do both units. Gotta tell folks that they need a bunch of paper towels when they clean the cones. That's a mess. Also, I needed to clean my knife quite a few times when I was removing the gasket. All in all I'm very happy with the results.

Damn i did not even know this was possible, i just gave up a pair of AT 15`s that i had for like 24 years because of the foam surround problem.

I was super skeptical about centering the voice coil by hand without shims or test tones, but I found the "sweet spot" exactly like you described! I kept pressing the center at the sweet spot as I glued the outer foam edge and my speakers turned out great!

making the holes in the new foam (for the screws) with a soldering iron is a nice way to finish the job...

I purchased your kit to repair my smaller Boston acoustics 350's. you guys are tremendous. I got an answer almost immediately on a Sunday afternoon during my repair. I cannot speak enough about how good of a business model your company is. Great, knowledgeable people.

It's actually easier than this video even makes it appear. Almost anybody can replace these surrounds. It's best to remove the large foam chunks off the cone with a knife before doing a final clean with alcohol.

The gasket is made of one piece of rigid plastic and could I think be used to center properly the cone when glued on top of the manual tests for verification.

In my country, it's like a century old tradition to play (loud, heavy bass) music while gluing the outer edge, that's the way we center the coil and glue it, while allowing it to glue itself without limiting excursion... but I never see this online.

This was a fantastic video. I recently sent my Cerwin Vega speakers to the Hi-Fi shop to send out to replace the foam. When I reinstalled them into the cabinets the emblem was tilted to approx 20' off center, just like you demonstrated in this video. I thought it would be a big deal to rotate into the proper position but now I can remove the gasket and rotate to the proper position easy-peasy! My question, is there a recommended adhesive to use in place of what you sell that is available at the local hardware store to re-glue the gaskets? Looking forward to hearing from you. Thx.

Just moved and noticed the foam was shot on my vintage CV's. This helps tremendously! Straight forward and quite simple, really.

Scored a pair of AT8s got ten bucks. Hopefully my repair goes as smooth as this one 🙃

Never worked on a speaker in my life. Purchased this kit for my 12” cerwin vega’s and put new foam on with ease. Great vid! Great company! Great product! Thank you

Thanks so much for offering such a concise and well-explained video on this subject. I have purchased my glue from you guys, and planning on doing a re-foam on some older Infinity speakers that I just picked up. Your video will certainly give me the pointers that I need for a successful job! Thanks again!!

Thanks so much, a truly excellent video, helped me restore a cherished pair of Speakerlab DAS-7 woofers.

Excelente buenisimo gracias por compartir 😉🇻🇪👍

Ordered the kit online, watched alone with the video, & could not have gone any smoother. Thank you so much.

thanks for the video and greetings from Berlin Germany i replaced with a kit from you the 8 inch subs from my Infinity refernce 50 and it worked very well.

Simply Speakers- Where to find 4 ohm replacement speakers 12 inch for original Cerwin-Vega AT-12? Surrounds shot but also destroyed cone in one cabinet- Ones with equivalent magnet, power handling, and frequency response. No low-pass filter on these woofers- direct input from main line in parallel with high-pass and band-pass filters in crossover board- any suggestion/post would be appreciated

What a excellent video I have the 1993 cerwin dx9 3ways cabinets speakers they are amazing I'm the original owner bought 1993. I want to replace my gaskets too. What a incredible detailed video. Thank you! I'm hoping I can order these parts from you. The video looks about 9 years ago?

mine took FOREVER to scrape off. I also accidentally pulled on a layer of the paper so it didn't look as good as on the video. I painted the cone black (originally gray as shown on the video) and it looks awesome

Ordered a foam kit for my Cerwin Vega AT-8's, followed the video here, and couldn't be happier. I'd forgotten how good those little speakers I bought back in college in the early 90's sounded.

I used this guide and the kit from your website to replace damaged old foam on a pair of '94 CV VS-100 woofers. Using the method here, I had absolutely no problems removing the old foam and installing the new foam and the voice coil is dead center without shimming--there is no rubbing at all. I also reused both gaskets no problem. This is my first time doing any speaker repair, so I was very hesitant to do this work myself. Even with your explanation I thought that the voice coil couldn't possibly be centered considering that pretty much everybody else says that removing the dust cap and shimming the voice coil is necessary. However, they were all wrong and you were right! Now my VS-100's look and sound excellent! I just wanted to comment here to thank you for the guide and also to convince anybody else looking to try this method that it does work. It took me about 4 hours start to finish with all the drying time as well. I used rubbing alcohol but did not put any on the cone itself, i just used an x-acto knife and my fingernail to remove the foam from the edge of the cone and used rubbing alcohol, a knife, and my fingernail to remove the foam from the edge of the speaker frame. The gasket just lifted straight off with a bit of even pressure. Thank you Simply Speakers! And I strongly encourage anybody who just need to replace foam to use this method, it's very easy if you take your time to be neat and follow the directions above.

Wow! The kit worked perfectly. My AT-12s look like factory new. Thanks for a great product, and informative how-to video. I could not be more pleased with the results.

Getting ready to pick up some AT-15's tomorrow for cheap with the refoam kit included..This vid is tremendously helpful.TYVM 🍺

What a fantastic step by step video. Where are you guys located ? I'd like to get my D7 speakers refoamed .

I refoamed the 12" bass speakers in my Cerwin Vega DX-7s. I was nervous that I'd ruin it by having it rub after I attached the speaker to the frame, but it's easier than you fear. All set! GREAT video, good pace, reassuring all the way through.

Thanks so much! Just replaced the foam on my first pair of Cerwin Vega’s. I’ve never heard a pair, just waiting for the glue to dry on the surround trim gasket. Thanks for selling the kits and sharing this video, I feel like I really nailed the refoam, it’s not a hard task, but it was very rewarding.

Watched many instruction videos, this one is the proper and clear. Thank you so much!

This was such a big help. I agree, this is one of the best instructional videos I've seen on youtube. Thanks so much. Hope your business is going strong. I really appreciate it.

Excellent tutorial! I just ordered a kit for my Cerwin Vega AT-12's and looking forward to my 1st reforming thanks to your video!!!

These guys (simply speaker ) are the ONLY way to go when your doing speaker repair. I deviated ONE TIME on a set of reforms for some Bose 301s that I got from another distributor cheaper. And boy was they CHEAPER..they didn't fit properly, the glue was a dam joke. Simply speaker all the way.

The Cerwin Vega is giving me flashbacks of the early 80's woofer wars. I remember seeing them being advertised with like 3 20" woofers for $150. lol....Great tutorial nonetheless! Thanks!

great video! i recently bought some kits from you guys and this was stellar

I own a pair we bought in 1988 and the foam and gasket is bad. Excuse my ignorance but is that why they sound bad. I assumed it was something internal or electronic. I have had in storage for 10+ years but just bought a turntable and want to have a decent setup.

Thanks for this! I'll be working on my old speaker as soon as the foam arrives, and I'll watch this again too!!!!

Hey, i order these from you on Ebay.... To Finland =) Few days ago..Nice

My HPM-100s have greased cloth . 46 yo and still perfect.

Thank You for this video it is outstanding. i just ordered foam surrounds for my 1960's AR 2 x speakers. Thanks Tom

I just replaced the surrounds on a pair of Marantz 15" speakers. One was a piece of cake, but I had problems getting the other centered on the "sweet spot". No matter what I did, I kept getting scraping on one side or another. I ended up peeling it back off of the frame and cleaning it up (naphtha works very well). On the next try, I installed it dry (it was a little bit tacky after being cleaned-up) and carefully centered it on the sweet spot, which left it visibly out of center on the frame. I then put a single drop of adhesive at the spot where it was puled over the farthest, then again 90 degrees to each side, and finally one directly across from the first. After letting it set-up a few minutes, and confirming I was still centered, I peeled back the surround between each of the glue spots and glued it down. It worked like a charm.

Excellent instructions. Very helpful. You convinced me that I can do it myself

Excellent video! Even for old timers, the thought of refoaming can be a little intimidating, but your training video is very thorough and I'm pretty sure anyone can replicate this process, which is both practical and effective. I really appreciate the effort touching on possible missteps and sharing the techniques you've learned over the decades to mitigate the possibility of a botched job. Now... I just need to get my butt in gear and get started on my Sound Dynamics 12S foam surround replacement! Thanks again. 🎉

10:45. Good tip. Work smart, not hard.

One thing I did with my last refoam project was after you feel the foam is attached in a good position is to hook the speaker up to an amplifier and just play music lightly at a very low volume to check for voice coil rubbing sounds.

Thank you! My CV’s will live and rock another 40 years!

Instead of slowly attaching the surround to the cone, I've picked up some assorted lunch plates and bowls from resale shops (Goodwill, etc) that are just the right sizes to sit upsidedown over the inner lip of the surround. Don't leave it in place long enough for the glue to harden. Just long enough for the surrounds to stay attached without babying them. May take a few trips to find just the right size, but for $.50 or $1 per plate that you can use again and again, it's well worth the time to find a few of them. It might take a little trial and error to find what size you need for any one foam but in general the same dish can be used for most any foam for the same sized speaker. Might be hard with larger (15"??) speakers, but I have them for 6.5" (bowls), 8", 10", and even 12" foams.

no one read this it's just a reminder for myself 6:19

This video is amazing. I just ordered surrounds for my Sony SS-U542AV speakers that the foam surrounds just fell out of. I'm looking forward to having these speakers live again!

I got a rare XL-12S laying which got a terrible foam. I gotta replace it since it looks so easy.

This was a very informative video, my speakers didn't come out as neat as these but I was able to do the job!

Did anyone else hear Jeff Goldblum the whole time as he is working on the speaker? lol I did.

Brilliant video! Great thorough and easy to understand instructions. It is clear that you have a lot of experience. Unfortunately I live in Europe and we do have more limited selection of refoam and recone kits and buying from the US gets expensive, due to shipping and customs. I managed to find a refoam kit for my B&O Beovox MC120.2 locally and refoamed the woofers following your instruction video. The speakers now play like new. I can only positively recommend others to try refoaming their speakers as well. Great way to save money and better for the enviroment, than always throwing out and buying new. Next step for me would be reconing. I've also watched your video on this, so I think it should be possible for me to do. Thank you very much for making these videos!

Very good video. My only real critique is that I always cut the surround for the screw holes. It takes almost zero time and minimal risk of accidents. It also makes for an easier installation to not have to push through the surround with the screw.

You guys rock. The kit I got from you guys couldn't have been easier and brought my 30 year old Cerwin-Vega D-3 towers back to life! Check 'em out: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-S-_qrvu0Iqs.html Thanks again Simply Speakers!

FINALLY someone on the internet selling something that JUST LIKE IT SAYS IT IS! Thank you for the surround kit and the video.. was a snap..

I need adhesive do you have it on ebay or Amazon for sale?

Excellent tutorial!! My 26 year old At-12's are back to life. They never died, just looked like they did. Here i thought they still sounded good, but after this fix I realized what I've been missing. They sound brand new again

Absolutely love this service for all my old stuff. AND ANOTHER FLORIDA BUSINESS!!! Keep it up guys. They don't make speakers like they used to... Cheers to all of you.

OK I'm ready to refoam my vintage JBL speakers

I re-foamed my Cerwin Vega AT-15's using this kit. To clean the cone, I found it worked much better to lightly scrape the old orange foam off cone without the alcohol. Then I used the alcohol to remove the remaining black foam. Great kit, great instructional video and great customer service!!! Highly recommend this kit

Thank you so much. Your video is excellent. Easy to follow. So happy I found you guys and this repair kit. It appears that Boston Acoustics may be out of business which is sad. I have a set of Sub Sat 6 that are probably 25 years old and they still sound excellent. I boight the 4” kit to repair my mids. Sounds like new! Now excuse me while I go turn up my stereo 😊

This video was so helpful. I repaired a pair of Cerwin Vega VS-100's,with the common refoam problem. Sean even took his time out of his busy day to answer a question on the phone (unmistakable voice ) Very pleased! Thank You so much! Matt M. Pitt Pa.

Best "How To" video for restoring Speakers. I just bought some Cerwin Vega Model 26's from the early 70's. Hopefully the drivers are original. The edge of the speaker cone is flat. Funny, I bought at an Estate Sale and was carrying them to the car and someone offered me $300 for the pair on the spot. I probably should have sold them. Anyway, I ordered the foam kit from Simple Speakers. Waiting for the kit to arrive.

Awesome video! From a auto mechanic and an office building builder, you have my utmost respect to the details and presentation. I will def buy from you with confidence. Have a great day!!

I just ordered a FSK-12JL-1 repair kit for my fourteen-year-old PDR 12. I'll re-watch this video before I get to work on it. I've never done a speaker repair. Wish me luck!

Excellent and very informative video! Thanks so much! :)

Perfect!! Thanks for the video. I didn't know you could refoam speakers. Waiting for the glue to dry, CAN'T WAIT!! :)

I pulled out my 30 year old Sony speakers to connect them to brand new wiring in a new room with built-in surround wiring. Unfortunately, the two mains were starting to rattle because of the foam surrounds. I did a web search with those speaker model numbers expecting to buy entirely new speakers to put in the cabinets. But info for simply speakers came up - and a kit specifically fitting my speakers. I said heck, why not - $10 per speaker!? It took a few hours over a couple of days to scrape, glue, reattach it all - but they look brand new and sound brand new. Totally amazed and told all my "friends" on facebook about it. Very cool product, and mine actually went on easier than the video. My original foam surrounds were connected to the back of the driver cone, so I didn't have to scrape anything off! :)

Who thumbs this down? People who want to mess with voice coil shims??? This makes it easy.

Just finished my 10" vegas. Like having brand new speakers! Thank you for sharing the repair video. Best $30 spent this year...

awesome tutorial. Ordered a kit for my Cerwin Vega 12" speakers, and one 10" for my Infinity home sub. They work perfectly! Thanks Simply Speakers! Seriously, just awesome!

I almost sold my AT10 speakers because the foam was disintegrated. Had no idea the foam was replaceable. Thx for sharing. I love my AT-10’s and cant wait to hear them again after many years. My wife wont be happy about it but thats ok 😂.

awesome product! my cerwin vega 15" HEDs never looked or sounded better. video was a great help. very clear concise tutorial. Thanks!

Thank You! I thought my 4410 woofer was shot. I just need to replace the foam and you all sell a 4410 foam kit :)

when my cat saw you pick up the knife he leapt off my computer desk and ran

Commenting tonight on March 1, 2024, this video was an invaluable guiding resource while performing my first re-foam. I've long had a pair of Cerwin Vega AT-10's that are still working fine. I recently inherited a free pair of D-3 speakers with deteriorated foam surrounds. I just finished the job and they came out really well. I'm now confident I can repair my AT-10's should the need arise. Solid A-Z instructional. 👍

The glue comes with the Kit ? Or is it an specific one ?

Great tutorial! So much common sense, which ain't too common :)

Jeff Goldblum teaches you how to refoam.
