Thank you for watching the video. please support me. Thanks you very much. love everyone.
sounds like beating on my garage door lol
That's how they made some sound effects back in the day.
All that work and it rattles like the Ghost of Christmas Past.😂
Its the workshop rattling, not the woofer
@PHUSII it's all of the components that were just thrown inside and not secured! Why use braid nails that are just going to vibrate loose and plywood? Why not use MDF, Screws, and glue where they'd be less likely to vibrate?
Because he also used wood glue and plywood is much stronger than MDF and I do believe that the guy used maple veneer plywood which when stained and waxed will make for a beautiful box.
@@martinparr193 It's not about the strength. Its worthless if it rattles like this. So what if it looks nice and is strong if it sounds horrible?
Its like building a lawnmower that's fast and looks good but doesn't cut grass good at all
@@teddysickels1857 Wood glue is not going to vibrate apart. Plywood is lighter than MDF. I wouldn't want to lift a cabinet that size made from MDF.
I did this for years.
That sub and box are solid. That isn’t what is rattling… it’s everything else in the shop that isn’t secured. Most likely the wall siding or tools on the workbench.
At 22:30 he just dropped the loose board inside and closed the thing up. That might not be what ratteling but that is janky as heck.
@@lobster8009 Agreed
@@lobster8009 🤣🤣🤣
If you did work like this for years, I hope you didn't charge...
There's an unsecured circuit board he just dropped in there that is the rattling ghost of hack jobs Present...
Руки оторвать за такую работу
Its something in the room rattling, that sub is solid 👌🏼
Yep I was thinking that because there's a tiny delay.
they threw in entire ampifier inside it would be a mirracle not rattling
The board under, or some lose part.
der Subwoofer ist Müll
@@asdfghjkl1755Yeah so it isn't just me that was wondering about that ...
Thanks for recording that! I used to recone pro audio speakers. I always loved bringing a dead blown speaker back to new condition.
Respect for the effort , how many of us who judging this man could do what he did ? For me is excellent try , if we don't try we will never know or learn . Is from mistakes we learn what's right !!
yes excellent TRY. i did my diy 12 incher. and the fact the wiring keeps getting lose after some playin no matter what i do is frustrating.
Dude this restore went completely different than what I was expecting 😂
😂😂😂
Through all those components in the back without securing them isn't the vibration just going to bounce them around
With the knowledge he has to be able to do what he just did, how could he possibly not know that the parts need to be secured?
He very likely didn't show that part because he believed the viewers were intelligent enough to figure that out.
Yes. Absolutely.
@@markchidester6239 His believe in his viewers is ill considered.
@@astheworldburns3590 Agreed. Probably 90% of the average population are fucking idiots.
I noticed that too
Electronicals will probably last 6 months. Then broken solder and other pwb problems. Interesting build though.
Пойдет. В индийских боевиках удары озвучивать само то!
Ахах))
"Дышшш" 😂
Рокки бальбоа 🤣
give the speaker restoration an A+. a bit concerned about the box. good plywood was used but no silicone to bind box to help with rattle and no insulation for circuitry. box gets a C. good job.
Working with what you had & probably on a small budget, I think you did a pretty good job. If it does the job that you built it for, then that's ok.
I doubt they are going for quality here. It just has to be loud loud loud for some concert venue. Did you see those transistors? I think they were "used" as well, lol. Gotta commend the Asians, they know how to rip off a quality design and make it cheap cheap cheap!
No isolation, the circuit boards just random lose inside the box? They shortcut at some point of the movement and rattle. Nice work, but in many ways not good enough...
I don't think they left the pcb board loose - do you?
@@jakoblindekilde5832 yes!
@@jakoblindekilde5832I’m sure he did
@jakobl，，❤😂😂😂😂😂😂😂‘’❤❤😂😂😂😂 ，🥲🥲🥲🥲❤🥲❤❤❤～❤
Attaching the board actually causes MORE vibration because it's then firmly attached to the vibrating surface of the enclosure. Either use rubber anti-vibration mounts or let it free float. Both methods are equally viable.
Would like to know where the replacement speaker cone came from?
Agree 👍👍
Just search for "replacement speaker cones" - one that size is around $22.
он там стоял новый. ютубес перед спектаклем его снял, потом обратно поставил
You know that’s going on one of those crazy tractors with huge bass!
Я видел мультфильм где медведь на пне играл, так он там почти такие же звуки извлекал.

Звук. Это что доски перекидывают с места на место? 😂
И никого не волнует почему короб скрипит и трещит весь, наверное потому что такие вещи так не собираються,это ж не колонка для пк с мощностью 30ватт,и для 21 дюймов динамика, очень слабый усилитель, показать людям что такое возможно собрать дома это хорошо,но качество должно ж присутствовать хоть чуточку
The B roll of the rain was great storytelling.
Did you see the brick wall? Everything done there is done fast and cheap.
22:32 плату не закрепили, сместится и будет короткое замыкание.

Looking at the replacement of the bottom coil support wondering why. By the time the amp wiring had started I understood. Way more than the title suggests. 😊
There's 5 minutes of my life I'll never get back!!
If the worker has on flip flops you know it's gonna be done right 😂
I would give them a +5 for the speaker restoration but they get a -5 for the cabinet and circuitry so that give them 0 out of 10. Thanks for playing!
Another -10 for the final sound

I think it's the 3,5M views that plays well...
Homemade table saw you done a fine job with that
Not something I need to watch, but something I enjoyed to watch nonetheless. Thanks for the upload. Pretty cool stuff.
If only I knew those center cones could be replaced separately back in the 90’s. I purchased a lot of JL Audio subs with collapsed cones for cheap. An eyesore, but worked to spec otherwise.
Столько усилий для дребезга))))
В 86г 10ас-403 перематывал тк сгорел усилок а за ним и катушка, сам удивляюсь как шестикласник(я :)) смог это сделать но потом не мог по звуку отличить колонку от заводской (одна сгорела) . Главное в конце покак клей не до конца застыл отцентрировать катушку чтобы не касалась магнита, смотрится невозможно но навеяло
@@ilgizenikeev4114покак
@@ilgizenikeev4114 to center the coil use thin plastic of 1 to 1.5 cm wide and approximately 5cm long you can use old xray to cut the plastic and use it to hold like this 2:57
It's the shed rattling. Brains are for using, try it sometime!
Umm...am I the only one who noticed it didn't work?
😂😂
I see the same.
They used the membrane of wrong depth or wrong density.
So, the magnet is striking the bottom of the coil cup.
Did you guys listen to this on a loud stereo system? I'm sure the metal noises you guys heard were objects nearby getting rattled. I think it's a bad idea for people to try to demonstrate subs on TH-cam, though. There's just too many variables on the viewer's side to really hear what they are hearing.
@@666kuzya666no thats everything in the shop rattling
@666kuzya666 What membrane are you talking about?
Honestly, first "dude repairs a thing" video that I liked and wasn't a pit bike painted black and rustoleum. Cool to see this being done. Good work, man. 👍
Every subwoofer company out there: buys same basket made in china. Puts same voice coils, suspension, and surround in it. Puts on a different cone and logo. "our sub is the best one out there"
Lol that’s every company these days
@MrElectricity @0:09 - What is the fluid you used in the beginning????
I built a home theayer sub with a car subwoofer and amplifier once . Used a hefty 12 volt power supply and capacitors . Sounded great .
What product do you use to remove the glue?
Probably high % rubbing alcohol.
Acetone or 99% isopropil alcohol.
Where do you get replacement parts for speakers?
Good video, I never seen cone restoration. I like that at certain point he is wearing a winter jacket, yet he still wears flip flops :D
Great woodwork. Where’s the damping material?? How was the size of the baffle determined??
Non existent. Undersized.
Still a massive woofer though. When it gets loud enough maybe it drowns out the rattle.
❤😊 hello Mr Electricity. If only I was as talented as you are. I would repair my speakers and receiver. Have a good day.
My bullet teeters got more bass 😂 lol.
Amazing woodworking & solid build tho. 👍🏾
Мы в автосервисе рваный диффузор от сабвуфера зашпаклевали стекловолокном😁
Сабу пофиг, он только бас и гул выдаёт, вообще незаметно из багажника будет, хоть в три слоя поверху стекловолокном заклей, там подвесы в них такие тугие и длинозодние 😅😅😅👍👍👍
I don't think I've ever heard a sub clip like that before.
It's nice. You built a very nice subwoofer box for that. If someone reads this I want to say the best 18" Pro Audio PA subwoofers for the price are Rockville Audio and Dayton audio and a few others. I have had an 18" $175 CT Sounds Tropo and did some TH-cam vids in my bedroom of it on a Hifonics BRX2000.1D amplifier and it also sounds amazing.

Dayton drivers are quite nice.

that clear plastic you put on the back of those transistors are really good at blocking electricity and heat. you should have isolated the back of the board if you were worried about shorts.
That's likely mica insulators as the back plane of the transistor is at the collector/drain's voltage/potential and must be isolated from the heat sink.
Looks like something you'd buy out of the back of a sketchy looking van in a Walmart parking lot.....👏
Yes but how many ppl did this? I did as a kid
maybe they like the vibration? so much asmr to just give up in the end...truly well done, maybe securing and insulation etc come next and they just wanted to see if it works.
Fantastic and beautiful thank 😊👍👏👏
Sounds like he left a pie pan inside 😂
I'm confused, was the coil centered to the top plate and i just didn't see it?
Amazing job. I just love it when you can recycle things like that. Many things could be restored and sold cheaper for people that can't afford more expensive things. I noticed lots of waste here at the recycling centers.
i watched the video till the end.neat and precise great job
За исключением нескольких манипуляций с электроинструментом, показано всё, чего делать не следует или надо делать по другому.
First time I’ve seen anyone else actually repair a speaker. back in my teens and early 20s. I used to get a lot of 6 x 9“ car speakers, and a few home speakers that didn’t work. Usually the car speakers had cones that were split all along the outer edge which made them rattle. One trick I would use is to simply cut out the damaged part, Take a vinyl tablecloth with the cotton/fuzz backing. Cut a donut out and glue it to the speaker cone/frame with model glue. I had one set that had been sitting in a vehicle in a salvage yard for years and after I repaired them, they were perfectly fine for several more years. The other thing was where the wires for the coil come out in attached to the cone. The black epoxy glue would become brittle and crack, snapping the wire in two. Those were usually fun to try to repair.
i had the same speaker back then, its not a subwoofer but a huge woofer that goes in monitors for outdoor shows or nightclubs, i used to crack the wall of my room with that and an old marrantz amp
Фанера тонкая для такого динамика. Нужна фанера 20мм минимум.
так столько по виду и есть
Very nice job
LMAO that table saw! xD
I am impressed by the minimal tear-out in cutting and routing the plywood. Pity about the raw edges and glue smears.
Nails and plywood? Next time, use screws & remove them after the glue sets and use MDF. Also, make sure to secure all interior components.
he did secure all the interior he just didn't show it. while i agree mdf is a better airtight box that plywood works well enough to not be a major issue.
plywood is acoustically better than MDF board
Plywood is layers of wood held together with glue. There are imperfections in the wood & in the gluing process that cause distortions in the sound. Those imperfections are not present in MDF.
@@CnJForge We are not talking about the lowest quality plywood with manufacturing defects, but about the real material which is many times more expensive than MDF board.
There will always be imperfections when using real wood...always. It will crack & splinter. MDF or HDF does not do either.
Are the plates loose inside the box?
What liquid compound do you use to release the glue
There must be a part 2 where they pad the inside of the box with proper sound deadening material.
can hear the plywood box
What is the chemical you used in removing rubber adhesives. Thank you for your reply.
IPA for sure ( Isopropyl alcohol )
I wish we could still buy M.E.K. The real stuff, not the m.e.k. substitute crap everyone sells now.@@ZAPATTUBE
I couldn’t stop watching!!!!! 🤷🏻♂️
For the laymen like who is looking to restore a couple of subs. Would you mind sharing the various glues and liquids and their purpose? Thank You. Also I saw where you restoring a JBL subwoofers electrical components, where did you get the electrical components from and that soldering tool? Thanks again.
Nice work but give more details of what kinds of materials you are using. Solvents, glue, etc.
А музыку он может играть? Или только звуки перфоратора?😅
yes, but most of us don't have access to that wee bottle of yak piss which must be magic
A lot of my repairs are like this. It's the easiest way to go about it when only the cone is damaged. Solvent doesn't have to be used and is faster with right tools and technique. But well executed.
started so good, but ended bad. janky AF just throwing in those circuit boards. No isolation and nothing, just rattle rattle 😂
Hi my name is Joe just have a question where do buy the parts to restore any speaker thanks so much

Когда то я перематывал 10-ГД30, больно они горели у нас в общаге, от перегрузки,😂😂😂
transistor will operate in high temprature without any ventilation ,at high levels which leads to distortion and destruction also affects transformers secondary winding.....
The speaker isn't making that noise, it's something in the garage. Nice job!
Sounds like someone off camera banging on a piece of sheet metal with their fist.
I think it's the entire garage 😄
Loving that table saw setup.
Nice work on the speaker repair.
Maybe add some silicone at the joints to seal the cabinet better
Great re cone video of a big ass speaker
Весело смотреть на эту дичь)) особенно проОРАЛ с усилителя АВ класса на ватт 400-500 на вид. засунутого в закрытый бокс без вентиляции))) а еще с трансформатора на 2кВт номинала... хотя тут бы хватило 500Вт трансформатора. усь уних сгорит от перегрева через 10 минут работы этого саба...
TEMU factory refurbished.
It would be easier to head the depth of the bass by using foam lining in the box. I did it to my truck as a kid and it helped out tremendously using Dyno Mating
I built simple particle board boxes once... This box is elaborate in its own way
How NOT to install boards inside a speaker... just drop them inside the cabinet and let them rattle around inside and distort the speaker! ALSO that cabinet needs insulation inside!

@@KellyMurphy Did you NOT hear that loud vibration? That noise was the plastic boards vibrating against the cabinet... Oh and I worked for Klipsch for 22 years, so yea I can build a speaker!
it's not subwoofer. it's a woofer.
Yeah you are right
No its a PA subwoofer usually PA subwoofers like this one have woofer edge in it
Exactly
It’s a bass bin woofer… definitely not for sub bass, deep but not low, minimal woofer excursion

Не реставрация,а просто замена на новый диффузора динамика ! 🙂
У них если даже четыре винтика открутил и снял крышку и задул краской из балончика это называется уже у них называется реставрация 🤣🤣🤣👍👍👍
Might have less rattle if you fasten the components you just set inside
Fake af... 🤣
Now repair the huge woofer that Marty McFly blew out in Doc Browns garage. 😅😅😅

Hello there!
Awesome video!
I was wondering if you have repaired 6x9 speakers?
I have two of these speakers but finding repair kits are very scarce.
The rubber gasket on both speakers are damaged beyond repair.
I wonder if you know how much the full repair kit would cost?
Were would U get a new sub skin from to re-furbish one
Great job. Any idea what the free air resonance is of the driver? Thanks. Jeffrey Z. in SC
I'd like to see the mechanism used to place the voice coil at the mid range of the mechanical travel.
Where can I buy parts for the speaker ? The round black foamy material. Please give me a link.
Hi, what did you use to remove the glue? I'm talking about the chemical in the little white bottle. thanks

What kind of glue was that that you put on the outside edge does that come with the replacement kit
