Refoaming an 8 inch woofer

[SpeakerFreak95]

nice video.

[justinwalter321]

i bet no one watched the whole video with out skipping anything

[redneck4lifeish]

@justinwalter321 i did

[SpadesHeart]

...what kind of glue is being used here? thinking about doing this with some old speakers to make a little extra money for school.

[MrAudioresearch]

i love the fact that there not speaking English but there is 1970's rock music in the backround

[MrAudioresearch]

that rubber looks rotten its not supposed to peel away with ease

[Jakester100]

or you could just buy a better sub

[Jx1x3]

use pot people!

[newsmanbluesman]

oes anyone center cones with shims anymore? even in frigging holland - about the most hi tech place i can think of

[alterna6]

Marillion! Good music at least!

[djlau1]

wouw netjes!! goed gedaan

[rockhound694u]

THE KEY IS THE POT.

[blackfeetballer1]

r u chewin gum or sumthin. fuckin spit tht shit people dont wanna hear tht shit

[iintro79]

where can i get some of these little woofers?

[InvaderLive]

sounds like hes jacking off

[jjfranky123]

isn't duct tape easyer? lol

[vantageIIx]

@jjfranky123 Sure, but it's also easier to replace a cracked windshield with a piece of plywood, or to find a refrigerator box instead of buying a house. :p

[rockhound694u]

@jjfranky123 ONLY IF YOU ARE A REDNECK SO GOOD LUCK WITH THAT

[jjfranky123]

@rockhound694u as a mater of fact i am a redneck but im also an audiophile, i meant use hi-fi duct-tape

[dmtmas]

does it matter what kind of glue you use? what's best?

[gomlChapfizzle]

i am refoaming a cerwin-vega d9 15" sub soon your video helped alot thanks

[lxshomeproductions]

i opened up my subs box today to find my foan ring completely gone

[miragef19]

but the question is will it blend ?

[hahaOSAMAhaha]

i love my bass :D

[09hibbs]

can anyone else here and the beat goes on it the background?

[sodie77]

Thanks for posting this video. I'm going to be fixing one of my car speaker foam rings soon. The only other choice was going over to the jeep dealer and paying $170+ for a new speaker because it has a stupid amp attached to it.

[bassinaterXD321]

i got a pair from my grampa hooked em up pput them on half voll and the foam came off in chunks lol

[234nikz]

they didn`t take off the gasket wich is cind of stuped from them

[dragossh]

what excactly is that foam? where and how do i find it?

[polyphonium]

@dragossh Google "refoam speaker kit" There are several sellers online, and the kits are not very expensive. (A 12 inch woofer kit costs about $12-$16 US per speaker.)

[trident3b]

humm.. how did they check that the voice coil was not close to the magnet, I mean I saw no specific centering goin g on here. I'm looking for a video to ensure centering. My LX1000 bass uint only need a minor touch on one side (the foam has almost gone by itself, and one immediately notices the contact of coil to magnet which I want to avoid by perfect centering if I try to refoan (with rubber this time!!!) myself.Anyone guidance would be appreciated.

[ABLACKX]

@trident3b Good point ! in my opinion -or as i would do- i'll just make the spider do the centering and leave the (cone and foam gluing to the end ) but i don't think it would work !! i'll think about it

[PojeMetal]

i thought you were destroying it at first xD, 

[thebestofall007]

rubbing alcohol helps a lot when removing the old surround/gasket material. it softens it up and also cleans the surface so the glue sticks better. just make sure the alcohol dries before applying the glue.

[truerene]

no mames wey!!!!, que pesimo trabajo hiciste, en primera nisikiera limpiaste bien el cono ni el esqueleto del woofer, en segunda no quitaste el cubrepolvo del cono y al no hacerlo se descentro la bobina.

un consejo wey!, "las cosas hay que hacerlas bien y a la primera"

[dkrasniak]

Please put a note on your video to never use the chisel in that manner where you point it toward your own hand. Always point the chisel away from your hand while using it!

[Udamasta]

@dkrasniak i was thinking the same thing like if he slipped it would have been bloody.

[Udamasta]

@dkrasniak i was thinking the same thing like if he slipped they're would have been blood.

[MrAudioresearch]

@dkrasniak its only a chisel not a knife its not going to kill you

[EdmDude]

6 people blew their replacement woofers.

[89grand]

Boooo! The dust cap should have been removed as you need to shim the voice coil to make sure the voice coil is centered. Otherwise it's a total crap shoot as to whether is will have voice coil rubbing or not. Otherwise, it was a pretty good video.

[MrEinstain]

@89grand What are you talking about? The only way to achieve what you say is to play a REALLY low freq,high power signal in the woofer while the glue is still drying.

[89grand]

@MrEinstain What? When you refoam a speaker, after you remove the old surround, you also remove the dust cap, then before you glue the new surround on you put 4 shims between the voice coil and pole piece to keep the cone centered while you glue the surround on. Not doing it, like this video, results in hit or miss results. It's a lot of work to refoam a speaker just to find out the voice coil rubs afterwards because you didn't do it properly and skipped a step.

[GanjaStuPipesUp]

@89grand Mate, of what do you speak? I'm right in the middle or re-foaming me speakers & I thought it was a piece of piss to do. Have I missed a step then?

[89grand]

@GanjaStuPipesUp Well, I don't know. Some people prefer to use shims between the voice coil and pole piece and some people use low frequency test tones. If the particular speaker has a tight gap, you want to use one of the methods.

[SaucyBegger25]

classic tune by the way

[nini073210]

lol 0:43 is basically what my woofer looks like(:

[trymesucker]

@nini073210 mine 2 :D I played bass i love you.. and it was like blloooooowaawawwa wawalwoolawoalw. I made it tho, with a 30 year old speaker...

[PatandUli]

good idea with the pot !

and the cable

[PatandUli]

good idea with the pot !

[Haskeo]

i have a pair of sony apm-33w speakers that have square woofer drivers i can't seem to find any square foam anywhere can some one help me?

[mazda2284]

@Haskeo they are like impossible to find foam for , i have the APM 270's , i have videos of em , but ya they are rare to find.. how bad are they?

[Haskeo]

@mazda2284 the foam is completely rotten off i managed to find a new pair of apm drivers but they are 1inch smaller than the original so they don't fit in the box perfectly but atleast i can get music from them...i uploaded onto my profile on youtube take a look.

[salazam]

ik vindt dat nederlanders het meest geduldige van mensen zijn.

[action571]

where do you buy the foam repair kits

[WooferRepair]

@action571

at speakerrepairshop

[GanjaStuPipesUp]

The only speakers I really love are Mission speakers from the 80's, so natureally the rubber is pretty-far gone on them by the time I get my hands on a pair. After about 6 months I've been throwing them away because the rubber has rotted! Aaaargggghh! I can't believe it never occured to me to repair my speakers before.

[WooferRepair]

@GanjaStuPipesUp

Never throw your woofers away, in 99% there's a second life possible!

[stereoguy63]

Appreciate the effort, but that is an accident waiting to happen with that chisel....pushing it into your hand. Don't ask how I know that :). You HAVE to remove the dust cap and shim it. How on earth can you center it that way? Shims would eliminate the need to empty your laundry basket too. Oh well.

[WooferRepair]

@stereoguy63

Of course you can do it this way, BUT: some woofers, like Dynaudio, have a non-removeable dustcap. They need a refoam this way!

[GladiatorGage]

how much does the ring cost?and where could i get one at?

[gluemanred]

@GladiatorGage Look around on google. I found 2 for $28 and free shipping at an online store for my old kenwood speakers

[libertyqueen]

Very good video. Excellent repair work by the woman and excellent video by the man.

[Shitsahoooio]

you done this be for :)

[DillonBerkley]

How would I replace a foam ring for a 10" 2000 kicker comp vr? The ring was sewn on.

[PeI2PeTuaLMoTioN]

@DillonBerkley well, you could just re-cone it.

[DillonBerkley]

@PeI2PeTuaLMoTioN I actually did a good deal of asking around and figured out the kicker has a subwoofer upgrade program for 72 bucks a sub. Considering Ive had the subs for 10 years and that is a $60 price cut ill take it.

[jarederajarederaj]

How much of a sound difference would it make from it playing when its defoamed and when its replaced???

[1JasonMraz]

@jarederajarederaj your question makes absolutely no sense

[jarederajarederaj]

@jarederajarederaj ok... im saying play the speaker without the foam and then play it with the foam after you are done refoaming... does it sound any difference???

That hard to understand?

[ExpertOfSound]

@jarederajarederaj

Yes, it will sound very bad.

It won't hold the air in the enclosure, and it won't align the voice coil correctly, causing it to rub on the inside metal and magnet area.

[WooferRepair]

@jarederajarederaj

No difference if you use the right ring. Right in terms of shape, size and thickness.

[MrRobban1234]

it's called a surround not a ring!

[Lordgeek4]

Is that 80's german pop music in the Background?

[Lordgeek4]

@Lordgeek4  Scratch that, I mean Dutch?

[kykareky]

@Lordgeek4

this is Marillion,

googl it

[vm756]

非常にいい仕事は、かわいい声を笑私は愛のビデオがある

[CyberNetTV]

may sound like a dumb question but why???

[graffie]

my mama always told me: cut away from you.

i think that goes for chisel as well.

[DjJonnyR]

lol buy more glue xD :D

[kevin10r]

i never seen a subs surround come out that easy

[snachicat]

@kevin10r you've never seen a really old sub's surround, then :P

[unitedtote]

hey this video is not aloud here

[kibidk]

Bad technique. You need to use shims in the voice-coil gap to ensure perfect alignment. If the speaker worked properly after this, it is pure luck.

[david96888]

@kibidk dude... he isn't reconing it. He's just replacing the surround. He can't align it with shims unless he takes the dust cap out. Besides, it's not like he took the spider out

[kibidk]

@david96888 That may be....dude. But as you can see I'm not the only one who thinks this isn´t the best way to do it. The spider alone and this "kitchen-pot and clothpin technique" is not enough to ensure perfect alignment of the voicecoil. So yes, a correct refoaming includes removal of the dustcap.

[munkymania]

@kibidk just run 6 to 9 volts of dc thru the speaker when your ready to align the coil in the gap...saves removing the dustcap and using shims on the former..just an old school tip for those who wanna know

[WooferRepair]

@kibidk

For your information, in the factory, where they put the woofers together, they son't shim at all....

[8671Dave]

And to handle any driver like that!!! basically ruins it anyway......Sorry

[8671Dave]

Why bother wit 8" sub? you better off with bigger cone driver for sub?

[kuza261]

none of yoll have shit on me, my speakers dominate for there price!!! only paid 12 bucks for em!!

[pokerface3699]

i always wondered why those foam surrounds were so fragile

[jonnyheroes]

What kind of glue do you use?

[tyler238]

hey i was gonna buy some memphis mojos 12'' from this guy because his dog chewed the foam off.. um do you know where i can find the foam kit for 12 inch memphis mojo subs? pleassse let me know thanks

[pressrolls]

good technique.

[yambo59]

By the way, nice video, good attention to detail and a nice clean job. This is tedious, dont think just anybody would have the patience.

[toretto667]

@yambo59 yeah men

[masterwolf1212]

@yambo59 not as tedious as a recone :P

[00015265]

bedankt ik weet dat jullie nederlands zijn maar bedankt zonder jullie kan ik mijn wofer wegooien

[bendover871]

LMAO wcchalo

[parkinsonc05]

good job.... i just did a 12 inch car audio sub and had to change the coil flex ring and could not believe i pulled it off..

[wcchalo]

how much does it cost for the foam??

[cichlidkeeper89]

it depends.

i refoamed my 2 15" for about $35

[hitachi654]

what i want to know is how ppl break the foam cuas if you use it right this wou;d not happen

[wcchalo]

i have a pair of JBL's from the 70's and the foam just like started falling off

[yambo59]

The foam gets old and dry rots, just kind of falls apart-- thats why I like the surrounds on my old Pioneer HPM100's, thier pleated cloth with a rubber coating, theyre tough and will never rot. I do love my cerwin vegas though, one of the best speakers out there. -

[Powerfrickel]

7:38 LOOOOOOL

[wesiem1993]

thx, ik zal zo snel mogelijk een bestelling maken xD

[MSNIMSM]

I first did this on a pair of large Advent speakers I trash picked and it took me about 3 days, but in the end, was soo worth it.

[masterwolf1212]

And for proof, because I am a type of person who backs up himself to prove myself correct, I have an 8" woofer that has no surround, but a 100% in tact perfect spider, and it moves side to side when you push it. A fly could move it! It was made of the material spiders are made of, and it was a perfect, non-crappy woofer. Like I said, I know this, the spider alone cannot hold it!

[masterwolf1212]

Yeah, negative two because an audio professional that knows how to do this says the right thing, mature people.

cumesoftware, your wrong. Yes, the spider centers it, but the main job of the spider is to keep the voice coil from popping out of the magnet gap and not popping back in. Without the surround, the cones weight can move the spider from side to side. The spider cannot hold it in center alone. And with the press of a finger while pushing down the surround, it will move it.

[WooferRepair]

@masterwolf1212

Our guess is that with a good spider, 80% of the centering is done by the spider. The rest by the ring. The main function of the ring is to make movement possible and close the speaker, not centering!

[masterwolf1212]

@WooferRepair Thanks, but I do know how speakers work, I buld enclosures, repair speakers, and have built my own, winding the voice coil aswell. Now for one, it doesn't sound so good on your part calling the surround the ring, its just not what its called. Secondly, it depends on the spider. If you have a multiple layer spider, maybe, but not a single spider, unless a rugged one. And what do you mean by saying close to the speaker? The surround doesn't move the woofer. And the coil is centered..

[masterwolf1212]

Wrong, this is worth a quarter star! All wrong. You need to take the dust cap of (the bump in the center) and insert shims between the coil and magnet gap!!!! Without the voice coil, the coil is free to move side to side! So now you probably put the surround on, and the subwoofer is a bit off its axis, and now you cannot push it as hard because it will rub against the pole. Don't follow this person

[WooferRepair]

@masterwolf1212

And again, there's more then one way to do it. Please don't flame our way unless you tried it. And again: how will you refoam a Dynaudio 24Wxxx woofers where the cone and the dust-cap are one piece? Please tell all the people who were interested in this small tip your way.

[banksstinger]

i did my own version of a "refoam" using a pair of 10" MCS woofers. I made a mock foam ring with painters tape, and used black silicone to cover it over and attach tape to basket. works like new, took about 40 minutes, and only cost about $2 in supplies:-)

[lorenzoruchtie]

Cool! Nederlanders :)

[EdmDude]

I'm gonna try and emulate this person!

I got an old unused 10 Radio Shack woofer to test!

[zvuchniak]

This should be called a tutorial how NOT TO DO IT. Basket and membrane must be perfectly clear of all old glue an polyuretane. That is done by chemicals, not by fingers. If you whant to center it properly, you must remove the dust cap. This woman is an amater. Please do not try refoaming woofers this way.

[masterwolf1212]

Lol. This is not a cell in science class. I beleive you are referring to the VOICE COIL not the speaker membrane. Lol.

[speakers11223]

i have raditotehnika s30a

and the surround is awesome

rubber surround and its not going to broke

[vampiregt600]

s30 =D nice. Its old like may grandma bro. And quality is shity.

[bastec666]

I want to re-cone a 6inch woofer with something really strong to handle abuse and then really nice rubber rings.....

[mafia8819]

hi:) im from norway;) do you know som place where i can bay the ring from? and what glue do you juse?:P

[bluesbreaker1]

Thank you!..so cool!

all my best!

Benjamin

[cobra8811]

Ah So You Can REFOAM.Can't Wait To Tell My Dad xD

[SaucyBegger25]

thats love for you lol. ide do the same i love all speakers, good video and back music marillion, oh yeah!

[wooferfreak]

lol BOSE?

[WooferRepair]

Nope, Dynaudio.

[Sweetness293]

cool, thanks. i have these old speakers that still are in very good shape, the only thing was the foam surround around it, it was torn and disinegrated when you touched it... I just bought new surrounds for it and need to put them on. thanks for the video, it helped me understand a little bit better the whole concept of refoaming my speakers.

[courtneymccaw]

u got steady hands my friend.

[stevenewman01]

Good job! I need to do this on my old speakers. I ordered the refoaming kit already, but I was a little reluctant to tackle the job lest I ruin the speakers, so this video is very helpful. It doesn't look that hard, or at least you make it look easy.

Thanks
