In this video, we show you how to replace the foam surround on a Cerwin Vega woofer. We use a 12″ woofer in the video, but all speakers are similar in their design and the way they are repaired. You can use this video as a guide to refoam most speakers.

Very good video I liked that you showed us just enough and then went on to the next step no need to see the complete repair plus you gave us tips. Thank you I will be ordering a kit for my Boston Acoustics A60’s. I haven’t heard then in years and they are great sounding bookshelf speakers 🔊. I subscribed 🔔
No need to be intimidated about re-foaming your speakers. This is a very easy task. You can do it. I repaired the DX-3's my wife bought me 30 years ago. I'm proud to say, both the marriage and the Cerwin Vega's are still going strong.
This I found interesting. I have a pair of big Pioneer 3-ways with 15" woofers that are worth saving, a pair of Infinity Studio Monitors SM120s with 12" woofers, Advent Legacys, (10") and Baby Advents, (6.5") among others that I'd love to do this.
Although, I must say, I have many speakers, both old and new, and any that either have, or ever had foam surrounds all rotted over time. Any speaker drivers using butyl rubber surrounds all seem to remain intact for years, with never any problems. Probably one good reason many manufacturers switched to rubber in most speakers.
I would have reservations about refoaming any speakers, in knowledge they will likely fail again, given enough time, and thought the idea might be more attractive, and I'd be much less reluctant if I could obtain rubber surround kits, instead of the the inferior foam which deteriorates.
Do they make butyl rubber kits re-doing speakers in all these sizes?
I have a pair or cervin vega D7 15". I was not the one that took them a part. They have a 4 part gasket and a solid ring. The ring has old foam on it so I am guessing that it goes against the foam ring. Where does the 4 part paper gasket go. Does it go against the metal basket or on the outside of the solid ring. Please help me get this figured out. I got my kit from you hoping it would show me. Help me please!!!
Is there any reason why you couldn't combine the final two adhesive steps (foam to edge and gasket to foam) to save time? Meaning, get the cone centered and adhesive applied, then go ahead and put your adhesive on top of the foam, set the gasket on and turn the whole thing over? Then you're waiting one hour instead of two. Any issue with doing this?
SO helpful. Many thanks.
Just ordered the kit to fix my set of L100T that I have had since 1989
I purchased the kit for my Advents in 2009. This video gave me the instructions and courage to try this. The speakers sound great. Thanks for your video!
About half way through I thought you were Otis from Devil's Rejects.
Do you do polydome midranges on Infinity Kappa 7s?
Bought a kit for my 6.5" Infinity bookshelf speakers and followed the instructions in this video and successfully replaced the foam surrounds and they sound great. Thanks for everything!
I've got a pair of Advent speakers that are angled like this, and resemble these more than your other two Advent videos. Ordered your FSK-8 kit, and this video helped me immensely. I was pretty worried about getting ripples when trying to fit a flat surface to a conical section while I'm racing against glue drying, but it looks like it's no issue at all. Thanks!
Getting ready to pick up some AT-15's tomorrow for cheap with the refoam kit included..This vid is tremendously helpful.TYVM 🍺
Little help!? I have a set of e712 vegas. Instead of buying used half melted crossovers online or expensive one's from gibson i upgraded. I got emb cx10 crossovers 1200 watts and a tx10 terminal. I've gotten as far as i can now. I need the original switching jacks in my e712 to work. I'm clueless and no aptitude. Ps i replaced my surrounds both sets already. L9 book case one's the 2nd set.
I been wanting to tackle these woofers for years, but after watching this video…It's gonna happen after 15 years….Cheerz!!!
Perefect tutorial. You are a maestro. Thank you
Great video I bought the cerwin Vega surrounds from you guys Do you by any chance sell refoams for pioneer CS-88A Tweeters
Hello, As an auto mechanic i did my fair share of tire patching, basically similar gel and rubber, but must be perfectly adhered to work, so i used my screen tool roller used for inserting the rib when doing screens and "stitched" this rubber like a tire patch and it worked well. I'm saying this because I laid on a little too much glue and wanted to make sure I didn't have any lumping of the glue.
Thanks for such a detailed video.just ordered my kit today.
Great job thanks ❤️👍👍👍
It's because people put stuff in storage units for years
So glad I found this. Just today I popped the grills off my MX-400s and the foam is coming apart! I'll be ordering a 15" foam kit.
Thank you… Luis
so it wont affect the impedance on the speaker it will still as a hole as an 8 Ohm speaker
Thank you very much, that was very kind, Luis
Thank you very much I am very appreciated, may be I expressed wrong, I apologize for the inconvenience, what I mean is that if the Drivers are 6 and 4 Ohms, the tweeter and the midrange, can I replace these with 8 Ohms drivers or can affect the crossover? Thank you again much appreciated, Luis
Hi, I need your expertise if you can advise me, I will be very appreciated, I had bought four Cerwin Vega Ls-12 and on two of them the drivers blew up, I wanted please to ask you if I can put the same drivers that the SL-12 have? There are 8 ohms, can do any damage? the ones that it has are 6 ohms, each, I am not sure why now the all speaker is 8 ohms, impedance… I will be please very appreciated if you can answer me, Thank you Luis
Awesome video
I would like to thank you for this excellent instructional video. I have a pair of CV DX-3 towers that I kept when my Mom went into the nursing home. Of course the surrounds were shot. I was just going to buy some new drivers when I found this. I ordered a kit from your Amazon store front. I wouldn't have tried this without this vid. The first one took a little while, but the second one was a "piece of cake". Thanks!!!
Imagine doing this and you puncture the new surround while installing the speaker
The best instruction I have ever seen on youtube, please keep up the great work, much appreciated!!
Finally got around to replacing the surrounds on several woofers.
Thanks to this video it was super easy, barely an inconvenience.
So far the only video/channel to ACTUALLY show the application of the glue to the outer(& inner) gasket mounting point.
Thank you.
The need for shimming the voice coil is when you replace the coil, spider, or a cone.
The spider keeps the cone centered.
You DO have to do the push down to check centering because you can move the cone off center and glue it down off center causing rubbing.
You just want the outer gasket edge glued down so its centered and not causing rubbing due to off-center pulling.
