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!
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.
nicely done sir, maybe you should check it.
@bkraz333 what happens if you do hear scratching? or its rough
That was a proper re-foam. Some speakers have strong Spyders, so there’s no
need to take the cap off. They will center themselves when the surround is
put into place. If you have a defective surround then it will go bad.
what is that liquid did you use to clean/rub the old foam off the speaker?
does the size of the foam matters?? i want to replace the foam of my
subwoofers 12″ but there are different diameters
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
You should work for the RIAA judging by your irrelevant analogy skills.
If you look closely, you’ll see the dust cap is off center, but the cone is
strait.
Just did my first re-foam. Cerwin Vega D-3’s. The trick is to TAKE YOU’RE
TIME AND DON’T RUSH! Can you tell me who the background music is from?
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. 🙂
Great work. We want to hear that bass bump
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.
But you don’t stop the car and start walking if you see a school zone.
Congrats!
Not a poor video, but I’m sorry, I have to dislike. Why are there people
creating videos about doing speaker repares and other things with no
experience? Everybody has to start somewhere, but there are experts who do
this kind of stuff everyday and can actually answer peoples questions. I
mean I’ve gotten my hands dirty working on cars, but I’m not about to start
making videos about vehicle maintanence. And to say f u to those that try
to correct your mistakes is ignorant. i.e. mojosico.
I need a large caliper in my garage :/
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
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.
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.
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
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.
Not all re-foams need to be shimmed, especially if it has a stiff spyder.
nice video. thanks bkraz333 can you please tell me if i can use any repair
kit to fix the cuts on my subs ? please let me know. Thanks
@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.
With all due respect you missed the MOST IMPORTANT step of surround repair.
I have been refoaming for over 20 years and trust me you MUST pop the dust
cap and shim the voice before you add the surround. The foam part is the
easy part but will not work on its own. I get 5-10 pairs of speakers
brought to me each month by someone did a “do it yourself (DIY)” foam
repair and need them “fixed”. 90% of the DIY speakers have voice coil rub
because they did not shim the voice coil.
Dont Sound To Excited.
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??
@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
You don’t have to take the dust cap off if the speaker can properly center
itself. It’s not hard to do. If the speaker’s spyder is weak then you would
have to take the dust cap off.
What band do you have playing during the fast forward segments? They sound
awesome.
Wow
Its a dual voice coil…
i love the idea at 4:26
Nice Tutorial – i also have done that to replace my foam – the speaker
works good like new again – thanks a lot
old speakers are da bomb
Taineasy, where’s your video?
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 🙂
Dickhead.
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.
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.
rubber surround changes the specifications and sound characteristics of the
speaker. if it’s just going to be some subwoofer used in the car and you
don’t care about the sound, a rubber surround is better. then again MOST
car subs don’t last years as people mostly ABUSE them.
nice, weed scale.
to let any dumb ass know the only reason you would need to o this is if you
mis treatt you speakesr if you take care of them they shoudl last a long
ass time and never have to do this unless they are liek 30 years old and
foam surround in that case just replace anyways becuase years from then you
will just have to anyways and it coudl cause damage to the coil as it
becomes worn
what is the white liquid called that u put to glue the foam cuz i need some
for my speakers thankx
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
the best way to repair the speakers is removing the dust cap so that it is
centered perfect. you take the dust cap and put shims in the middle so that
it centers right. if it is off a little the coil will rub and this will
result in damaging the speaker and it will no longer work. i highly
recommened this for higher end speakers, such as the jl audio w6v1 which is
what i did.
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.
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.
