Shimming the voicecoil may be a good idea, however this speaker has been used every weekend since this video was made (over 2 years ago), and still sounds great, so I'd consider my repair a success.
Thanks for sharing. I just inherited a set of vintage Fisher XP-65s speakers and the 10" woofers are in desperate need of new foam surrounds. Great tutorial.
This video convinced me to buy replacement speakers for my Baby Advents instead of trying to refoam them myself. Thanks - this saved me a lot of time and headache.
a tip I'd wish to give to the viewers of this video: Elmer's Rubber Cement is a great preventative buff to put over a weak cone/suspension. If the hole is too big, I sometimes use paper towel dipped in rubber cement to patch it up. Sure, it adds a little extra mechanical resistance to the speaker, but I can't hear a difference nor have I ever damaged a voice-coil by making it too restrictive. And like always, thanks for the great videos
I said that I consider my repair a success, which I still do because the speaker still sounds great. I never claimed this was the only way, or the best way to repair a speaker.
Niacin. Billy Sheehan. Good choice! Oh and nice video too… I’ll be replacing the surround on Velodyne UL15 (also servo-driven) and this was informative. Thanks!
He did check for centering issue after gluing. It was just fine. Doesnot have to be accurate at atomic level, just that Voice coil does not rub the metal.
@bkraz333 thank you so much. For now I have put some low quality cellotape on te back but I don't know if its a good Idea. The speaker (Peerless HDS-164PPB PPB diaphragm, 33 mm) sits inside a ported box. I am making it as a project for school.
I used an old Heathkit tone generator to keep the coil centered when I redid mine. Different vendor (My Audio Addiction), but pretty much the same kit.
i have a tip for you, when you buy a new speaker, rub baseball glove oil on the surround and it will stay soft and fresh for a long time, longer than normal
@bkraz333 thx very helpful. Btw since its old should i even bother paying $20 to fix it? The tweeters seem to be working fine. Not sure about the bass though. I don't want to fix something that can't be fixed to begin with. Or it could be like you said the surrounds are having a huge affect on the bass since its not even on the driver
My cone doesn't have a big flat lip to put glue on like yours does, but the surround I just ordered does. Any recommendations to make that connection work? Should I try to force the flat part of the surround down into the cone?
Ok stupid questions. Does the surrounds on the speaker have any effect on the sound quality? I am trying to repair an old 1991 sony ss-tl1 speaker and the surround foams on the sub woofer are gone. The bass without the surround foam is very lacking. Will it change once I add the surrounds? Or did i ruin the sub woofer when I used it without the surrounds
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 !
any tips for re-attaching a gasket? somehow the kid i bought my subs from blew them off, and he was underpowering the subs. they're alpine type e's, but i think they were just initially poorly adhesed, but i don't know
i noticed that the cone surround was blocking the mounting holes. the speaker i ordered has half of each mounting hole (four mounting holes) 50% covered by the speaker cone surround. i'm wondering what do to as the bolts can't go through the holes unless i try to cut the surround out of the holes. what did you end up doing to clear the mounting holes?
HI , I currently have a Yamaha YST - SW 80 subwoofer which I have accidently damaged the surround foam and it has a small torn bit, if i consider to change the foam do I need to match the foam rubber kit to the making of the subwoofer or any foam rubber kit would work on it? Thanks :)
Dude, now that I've found this video, you are officially my favorite subscription! I wish I could do projects like yours, like messing with arc lamps, DIY aerogel, all that good stuff. Also, I have (I don't know why) a strange passion for loud bass. The powerful thump of a massive car stereo makes just me feel really happy. Seeing you working with a subwoofer on your channel is an instant favorite! BTW, you should really look up what multi-kilowatt subwoofers can do to their car : ).
YOU are a success my man! Don't worry about those Debbie downers! When you reach a certain level of success and you will ALWAYS have critics which is how you know you've got your name out their. Great work as always. :)
@unstopable172 I found out you could use "Aileen's tacky glue" from Walmart, which is a thicker glue (than elmers). This glue is more sticky than elmers & useful for binding different fabrics, wood, or plastics.
hey i have a JL Audio 13W7 and the speaker was sitting at my garage and it got wet inside of the speaker, but with them time it dried itself. You think being that the inside being wet before will affect the speaker if i repair the rubber??
+Mark - his cone was polypropylene, which means you can use a wide variety of solvents since pp is quite hard to dissolve. If your speaker cone is any other material, i would suggest using an old style a razor blade. Sharp and really soft.

Well, that is a good one. But I was hoping to get a name of the author or at least the title of the song. Anyway, may the FORCE be with with you. Thank you for the comment 'gamerman'.
Not really. Ther is angled and straight attach types, but also the foam roll can be different shape, height. You can measure and find the one that is the closest to the original
The dust seal (spider) at the base of the speaker cone, where the voice coil is, keeps the cone centered. Also, gluing the surround to the cone first allows you to center the cone to the basket later.
Excellent tips putting nuts around the periphery, and newspaper under the diaphragm. Like other commentators, I am going to run audio through my speakers in the first few minutes of glue curing. Three 1990s speakers to repair this week: two NHT One (6.5” mids) and a Paradigm 10 inch sub. Thx for the ideas.
WOW!!! You needed to apply this speaker surround on a third Thursday in a month that starts with the letter A, with an ambient temperature of 75f to 83.2f while wearing corduroy pants and a thin brimmed ball cap otherwise in 17 years time it's going to reproduce a frequency of 14,000 Hz at 72 dB when it should reproduce a frequency of 13,995 Hz at 73 dB!!!!! Lord have mercy on your ears.
Your misunderstood. Your dual speaker connections are for your dual speaker coils. You have a DVC speaker and ther nothing to do with feedback. Instead it has everything to do with speaker wiring. If your speaker is a 4 ohm DVC speaker if you wire the 2 coils together in parallel then the 2 wires going to your amp is 2 ohms.
I really think youu need to center the voice coil. Remove the dust cap and use shims to center it before you replace the surrounding. Then glue a new dust cap. Edit: Just saw your comment about this.
I apologize about the spelling. I'm typing on my iPod screen keyboard. I have tons of callouses on my hands from years of construction and this glass doesn't read a strike sometimes if I hit it with a callous. Again sorry. But you;l get it . Click the link
If you change the material of the surround, the sound of the speaker will change, normally to the worse. If it used foam, replace with foam, and if it used rubber, well, use rubber.
The only reason not to use foam is because the sub is very active, like sundown where it moves an inch. If you use foam there it will tear. Foam is more mobile and you get a much richer sound. Unfortunately, it degrades much quicker
The measured specs are altered only very minor since the flexibility coefficient of most foam surrounds is similar to rubber. Fs, Q and VAS specs are mostly affected by the speaker's spider (the surround itself having less of an effect). Usually rubber surrounds are an improvement in sound particularly in the bass and especially if they are made of butyl.
@@flyurway what you do is play a 50 hz test tone on your radio I use a old 75 radio and use my cellphone with a rca jack to the aux of the radio. What I do is lay the bead of the foam glue and you start the 50 HZ test tone the volume turn it up enough where you hear the woofer hum and you can presser the foam down on the glue and if the foam is off center it will make a slight buzz so you adjust the foam to center there is actually a TH-cam of this also I think it was Springfield woofer repair that posted it.
@@floydbeard5073 Hi, thanks for the response. I also ran across another video last night where someone showed how he does it just playing music through it - he was playing Journey in this case, lol. His theory is that as long as you're playing "something" through it, current is going through the coil which is all we need. Pretty cool, I've learned something new! Thx again!
@@flyurway hey no problem. I had to do it that way on the pair of 10" rock fosgate. There are from the early 80's and I did not want to destroy the paper cone and paper dust cap. Playing the test ton worked perfect.
Nice job! And... to all the voice coil centering guys....... He put it exactly as the original was glued so alignment (if it was correct from the factory) should be right-on! This isn't rocket science....... OK!? Yes...... I build rockets.
you tell them Ben just b/c they say you have to does not mean you have to and besides if they going to say that to you what will they think when I show them scotch tape works well also soon as I figure out how to put video on here I will
I have started a video, and when music came, I insta liked video. Sick tired of life-hack-music, can't stand it anymore. Can someone tell me what glue is it? Is that like glue for wood, looks like it.
Since the speaker needed repair because of a rotting foam surround---why replace it with another foam that's just going to eventually rot? Install a RUBBER surround---yes they are available---and you will never have to replace it again.
stay away from simply speakers. They sent me elmers glue to use as a sealant on the foam surrounds they sent me that didn't even fit. And they sent me model airplane glue to use in the process. WTF!
WOW!! you needed to take the dustcap off to make sure the voice coil is centered . you will be fixing that speaker "REAL SOON!!" when you refoam it again make sure to do that when you refoam next month , if it lasts that long. it says in the instructions to remove dustcap and center the coil.. im not hating on you just letting ya know how to "properly" refoam a speaker.
Please use slightly flexible glue. Super glue is too stiff and is no good for this purpose. The foam surround is supposed to strech a little, making it stiff can wear out your surround faster
Anyone who understands this is faulty advice would remove this video. Why not remove it? Asked of the OP. Well somehow, it is making them money? Then, of course, the reason is ... caaChing.

very poor and inconsistent job never mention the glue type not tasting the glue... you are suppose to use a special turntable to apply the glue properly on the cone and firs on the surround upside down...if you have micro gaps left between surround and cone they will produce distortions...why nobody talks about type of material the surround is made from? the word "foam" is not enough because the foam can be made of very many types of plastic, polyurethane, santoprene, neoprene and even butyl rubber... soap makes foam too...hahahaha...sorry but not enough quality and expertise here...
your back ground music blew my speakers apart! now i have to replace them! well you explained how to do that.
That’s how super villains get views.

Is that still true? Have you refoamed it since then?
Thanks for sharing. I just inherited a set of vintage Fisher XP-65s speakers and the 10" woofers are in desperate need of new foam surrounds. Great tutorial.
This video convinced me to buy replacement speakers for my Baby Advents instead of trying to refoam them myself. Thanks - this saved me a lot of time and headache.
a tip I'd wish to give to the viewers of this video:
Elmer's Rubber Cement is a great preventative buff to put over a weak cone/suspension.
If the hole is too big, I sometimes use paper towel dipped in rubber cement to patch it up.
Sure, it adds a little extra mechanical resistance to the speaker, but I can't hear a difference nor have I ever damaged a voice-coil by making it too restrictive.
And like always, thanks for the great videos
Wow! Great soundtrack. You've come a long way in 12 years
Nice Tutorial - i also have done that to replace my foam - the speaker works good like new again - thanks a lot
I said that I consider my repair a success, which I still do because the speaker still sounds great. I never claimed this was the only way, or the best way to repair a speaker.
Niacin. Billy Sheehan. Good choice! Oh and nice video too… I’ll be replacing the surround on Velodyne UL15 (also servo-driven) and this was informative. Thanks!
Cool vid. Going to be doing this myself in a few. Didn't think about using a brush. Looks like it made the adhesive process neater than expected.
He did check for centering issue after gluing. It was just fine. Doesnot have to be accurate at atomic level, just that Voice coil does not rub the metal.
I just have a small separating area in the sub. Do i have to take all the foam out still?

Well yeah, it's just feeble foam, once you've got it glued down it's not going to move, just shove the bolts through or cut it.

what is that liquid did you use to clean/rub the old foam off the speaker?
@unstopable172
I found out you could use "Aileen's tacky glue" from Walmart, which is a thicker glue (than elmers). This glue is more sticky than elmers & useful for binding different fabrics, wood, or plastics.
does the size of the foam matters?? i want to replace the foam of my subwoofers 12" but there are different diameters
hey i have a JL Audio 13W7 and the speaker was sitting at my garage and it got wet inside of the speaker, but with them time it dried itself. You think being that the inside being wet before will affect the speaker if i repair the rubber??
Glad to see and hear that you got LUCKY......
If you play speakers with a broken surround you will damage the coil. That's why you need to tend to it before more damage is sustained.
Would you say a hour of music is bad?
Played only to test my amp which i also repaired but only one hour
probably going to try this, local shop quoted me $75 for each sub to get re-foamed .
What did you use to clean the foam off the cone, and did that come with the kit? I tried a spot with alcohol and found my cone melting.
+Mark - his cone was polypropylene, which means you can use a wide variety of solvents since pp is quite hard to dissolve. If your speaker cone is any other material, i would suggest using an old style a razor blade. Sharp and really soft.

Sounds pretty good..
Mitch Lalovie porno music
Well, that is a good one. But I was hoping to get a name of the author or at least the title of the song.
Anyway, may the FORCE be with with you.
Thank you for the comment 'gamerman'.
Mitch Lalovie the composers name is Jonny stayhard. The song was featured in a clip featuring Ron Jeremy in a porn called Fur Trap 3
Yes Im very familiar with this movie and the music completely reminded me of it!
Is speaker foam universal?
Not really. Ther is angled and straight attach types, but also the foam roll can be different shape, height. You can measure and find the one that is the closest to the original
Hey, is it the same thing to "re-foam" Cerwin Vega D 3-E? Thanks! :)
Helpful video, will give it a go!
Pretty well done video. I was wondering how you were getting around shimming the VC.
@bkraz333 what happens if you do hear scratching? or its rough
How do you know if it's centered stuffing it with paper like that.
The dust seal (spider) at the base of the speaker cone, where the voice coil is, keeps the cone centered. Also, gluing the surround to the cone first allows you to center the cone to the basket later.
Very useful video, the music playing 6db louder than the dialogue was a bit annoying though.
Forget the unnecessary music. What liquid did you use to clean the old surround off with?
can we get Jamo 606 8inch foam replacement from Speakerworks.com?
What band do you have playing during the fast forward segments? They sound awesome.
Shaun McMillan lmfao

Bad idea. The driver needs to be relaxed.
I wondered about that too but I think as long as it's relaxed when he does the final seam (outside edge in this case) it'll work out just as well.

Why not remove it? Asked of the OP.
Well somehow, it is making them money?
Then, of course, the reason is ... caaChing.
Shimming, or running an audio signal through the voice coil during the gluing process is an accepted method for centering the voice coil.

Any other method is based on luck, not science.
OK, this speaker renovation lucked out, granted.
But, this hap-hazard method, as presented, is not based on better, now common methods.

You can fix anything with duct tape. What kind of tape did you use?
