Un-blowing a Speaker

[@nozmoking1]

Really glad to see you use shims all the way around the voice coil. Some believe three is enough but the more you use the better the overall alignment and consistency of the clearance through the full voice coil excursion.

[@sudhirsumongkol8972]

Back in Thailand, we use (developed) film for shims and it works quite well. You can see it all the times on the streets around "Ban Moh" area in Bangkok.

[@briandeitz8209]

Agreed, this is one of my fav parts.

[@bamper42069]

@Jay B You do realize that this is a loudspeaker not a car sub woofer, also you must not know that this is rated at 123db continuous and it is extremely unlikely you can find a replacement 10 inch capable of that for 100 dollars.

[@nightrous3026]

bamper42069 i mean... i got a rockford fosgate P2 in great and usable condition at a yardsale for only $10...

[@MisterJohnMorales]

Clearly you are a person of incredible skill as you repaired that speaker rather effortlessly, making no mistake, doing each step perfectly (please no need for modesty). What I'd love to know is how many people inspired by how you made it look so simple gave it a try and simply destroyed what they were working on, because it's more than just knowing what to do, it's knowing how to do what you are doing extremely well. Great video, regardless!

[@jeffslttn3913]

As a PRO live sound technician with roughly 40 years of experience, I have to agree with the pro audio vs car subwoofer comments. This is a PRO audio driver -- a completely different animal than a CAR subwoofer. A car audio enthusiast criticizing this speaker is like a motorcyclist criticizing a football helmet! I have no disrespect for car audio enthusiasts, bassheads, or whatever they want to be called; if you're having fun, then have at it! However, the vast majority of these "professionals" wouldn't have a CLUE what to do if they sat down behind a console and a rack of amps and processors! Quite frankly, regardless of my pro audio experience, if I wanted an efficient, powerful subwoofer in my car, I would probably get a basshead to help me build it.

I would just go back to the local audio store and buy another 12 inch JL Audio Subwoofer.

Best how to video I've seen for this topic.

[@ExStaticBass]

This is quite possibly one of the best videos I've seen on re-coning a driver so far. I have a set of Behringer VP2520 cabs that are rated for 2000 watts. In reality the drivers are rated for 250 watts RMS and are wired in parallel. Assuming the rating on the cabinet was correct I drove them at 1000 watts which has noticeably damaged the motors. I'll be doing this same thing 4 times fairly soon. Thanks for the great video. Keep up the good work.

[@northwestcustoms6663]

Funny how some ppl say they would just go buy a new one. There is some satisfaction in repairing something. That would be like buying a new car because the motor or trans blew in it. If you have some skills and knowledge why not save a few bucks. Seems like smart money to me. I repaired my Cerwin Vega subs and they work like new.

[@krombopulosmichael6445]

[@SilasHemmingway]

Can an ice cream be re-coned if needed? I accidentally dropped mine. :(

[@Dina0wnes]

the "basket" is the metal part of a speaker. The part he replaced is the cone and voice coil from a "Re-cone kit". Cheaper subs do NOT have re-cone kits for them.

[@IAmLeutrimTopalli]

[@aerialwheel3719]

its a hi fidelity speaker. you dont really see the value in parts and design. its more of an integral electrical componenent that is finely tuned by expert engineers. whenever you hear live music, its most likely through paper speakers with a cloth or paper surround.

[@sergejnadazdin2234]

everyone is talking that your speaker is piece of junk.well i say that your woofer will be GOLD for me!i only have those moor small speakers

[@AmIonArock]

Quick story and a question for you, I bought two vintage Jensen 6X9 speakers. Using a multimeter one of the speakers was fine, the other I couldn't get a reading anywhere but when I hooked it up to a small amp, there was a small delay and then miraculously sizzled back to life, but with a coil rub sound. Is it possible that if speaker was blown before might have caused a short, fooling a my multimeter?

[@sergejnadazdin2234]

Everyone talking shit about him repairing that speaker should keep their comments to themselves. Obviously you know nothing about speakers. It is a PA speaker. I don't know about the new Turbosound speakers since they were bought out, but the older ones were quite good. This is a loudspeaker, not a subwoofer. You probably don't even know what a quality subwoofer is either.

Cool video. So the dust cap is it necessary for the performance of the speaker overall? I know dust isn't good for the coil but will a speaker still work the same without the dust cover?

[@Stonesmithable]

Great video . I have a 10" Precision Power flat piston sub that is blown. That crunchy sound when pressed on is terrible. This sub is HEAVY and I know its high quality, but how different would the repair be?

[@blackbird1234100]

probably not too different

[@blackbird1234100]

[@TimpBizkit]

I'm probably going to have to do the same to an Eminence 3012lf after not using a high pass on a loud bedroom testing. Coil is probably fine as it was nowhere near its thermal limit, but voice coil is slightly dented from hitting the back and it rubs.

[@buckyflex1]

I thought the "basket" was the metal frame that holds the magnet and what u attach the surround to. Isn't what he bought a re-cone kit?

Mount it upside down under the dash on the passenger side. Or you could remove the glove compartment and place it there

[@clubcar98]

What do y'all recommend? I'm trying to fix my grey Yamaha desktop speakers ive had since 1998. Any help is much appreciated.

[@Scioneer]

I'm laughing at all these "car woofer heads" calling that a crap speaker because it has a lower XMAX than a comparable car woofer. This speaker is designed for midbass in a high volume setting with a very large enclosure possibly with some kind of horn loading involved. Car woofers are designed for smaller enclosures and use higher wattage amplifiers to make up for the lack of acoustics said smaller enclosures have. This speaker would own a car woofer in an efficiency rating test, accuracy test, and longevity test. This is a professional audio woofer, not some overpriced toy designed to advertise to all the thugs in the area to bust out your vehicle's glass and steal your system for a quick buck.

[@charliearroyo4809]

Scioneer where did I say car woofer? Those two words never mentioned by me until now. Now it being a PA speaker then it is only good for voices nothing else. I have quality sound in my home and car. No has taken anything from either place.

[@A_Goat]

"No has taken"? ^

[@alwaysopen7970]

Only good for what? Little do you know of PA systems.

[@LordNorfick]

I have a question, so I bought some kmd se15-150 speakers 8ohms/150w and I have a pa system Sr - 6100 mixer amp I checked the fuse it's not blood but on the speakers sometimes the subwoofers won't make a sound but sound comes from the top part but not the bass part of it, so are they bad is there a bad connection they worked fine earlier but now that aren't. Unless I shake them lol then the sound lasts until I move them again I checked the cables swinging them around and the sound stays the same so I think the cables are good I also tried multiple different ones same situation I just need some help figuring this out.

[@Bluesr0cker]

you don't unblow the speaker, you just threw it away, you kept the "bracket" and installed a new speaker -_-

You keep the basket and the motor structure. It is called reconing a speaker. not unbolwing. For the speaker that he reconed it probably wasn't worth it. I have a $400 15" and the recone cost $190.

[@AXOU2203]

Very nice work ! Except for the choice of music. But instructive. What are those shime (? time) here to do ?

[@ronplucksstrings7112]

OK video, BUT...using steel wool (to clean glue residue off) around that strong magnet is way baaaad, and NOT recommended...if ANY even tiny particles get sucked up and into the voice-coil area, they will be difficult, if not impossible to remove, and all of your work is for nothing when they make contact with the voice-coil. I'd also vacuum out debris from voice-coil area, not just blow it around (but sticky paper was a good idea!)

[@sellsubz]

Ronplucksstrings You know your stuff Ron. Steel Wool would be about the last thing you want around that magnet structure. Undoubtedly some fibers will make their way into the VC slot and near impossible to remove and certainly no fun. Vacuuming as well should be done in the cleaning process. In the end the woofer was re-coned and seemingly working properly. With more practice some of the sloppiness will probably improve.

[@ppdan]

1:24 This is big reconing mistake when gluing the spider. You should only press down on the glue area to avoid putting some lateral tension that could de-center the coil once you remove the shims. When gluing the dust cap put a weight (coffee mug or glass) before pouring the glue around. This will prevent glue from running past the dust cap onto your voice coil. After reconing a LF woofer an extensive speaker burn-in might be welcome. Nice job ;)

[@johnnycee5179]

The basket, magnet and caps were all that was left. That's not unblowing, it's rebuilding. I personally found it very interesting to see this done. There was wait time for the glue to dry too. That was a 15"? This rebuild was worth the work done because I think 12 and 15" speakers aren't being built anymore or close to it, from what I have read. I just had 2 dust covers replaced on my Pioneers and new caps installed on one of them and they are 12" woofers, buying an active 1000 watt sub to accompany them will help them, so I did and that is a 12" as well, lol, wall shakers.

[@skydyverjym]

Rebuilding is the definition of unblowing. That is an 18 inch sub

[@johnnycee5179]

@@skydyverjym 18 inch! That's huge. Unblowing same as rebuilding, never heard that before

[@skydyverjym]

@@johnnycee5179 granted, I'm not as experienced as the vast majority, but once a speaker is blown, it's trash. Or you can rebuild it like here. Somebody correct me me if I'm wrong. If the cone is shot but the coil is still good it can be rigged, repaired kinda, repaired, or repurposed altogether into a vibration exciter or a bass shaker and I don't know what else. KZbin dml or flat panel speaker and bass shaker diy if you haven't already, they're awesome. But he said and demonstrated here the coil was very very shot. Only way to fix that that I know of is re-cone it like he did here

[@jeffslttn3913]

Virtually all high-end pro audio subs have a removable magnet for maintenance/reconing. Remove the magnet, THEN clean the gap. It's a hell of a lot more thorough. If you miss just one tiny crumb of copper, piece of steel wool, or melted enamel, then it's just a matter of time before it gets wedged into the gap and destroys the voice coil...

[@CassetteMaster]

Very nice job and funny to see all the high speed with the normal-pitch audio. Especially when it's extra fast and I hear your voice, but it is so fast it is unintelligible.

Frequency response is a much more costly engineering science than SPL (decibel). For many reasons, pro audio is a superior technology. One recording studio can cost MILLIONS!!!

I'd just done a recone on my Sundown Audio SA8v2 sub and I can tell you that is was a pain in the butt to recone. It's not a hard job, but being a little 8in sub with a heavy ass magnet and the way the basket/frame is made. It leave you with little room to do the reconing. But overall, reconing a sub is a fairly easy task to do and is cheaper than buying a new sub. You just need proper tools.

[@HarmonicaMustang]

If you have the time and it comes out properly cheaper (I'm not talking about saving $5) then it's cool. Nothing gives the satisfaction quite like having something work that you have built/fixed.
