@@100freerandomgiveaways9 i hate you. For real.
I swear a tear came down when he was ripping apart that beautiful subwoofer omg but he's an expert does a great job thanks for the video
Yeah but there was nothing wrong with the spider or cone all he had to do was remove the dust cap and replace the voice coil
Awesome vid man. Its nice watchin step by step and not chopped and cut. Thankyou for these indepth videos
Thanks, Hope it helped.
Lol in the beginning, a part of me was just like buy a new speaker. It was looking like it just needed to go to speaker Heaven
This same knowledge carry's over to 1000.00 Subwoofers also. We need more companies who support the longterm use of their brands. Instead of throw it away.
What can cause vc leads being seperated from where they attach to coil that is not visible at the (former?)
I have several high end or hard to find subwoofers that have damage like this. The voice coils are flawless, shiny no damage, but the leads that are integrated in the suspension spider are ripped away inside and the terminals make no connection outside?? Also a majority the spider has failed, lifted, or if there is a clamping ring securing the spider it has seperated.
Extreme over power in a high tuned big port area box and overexcursion causing the ripped away type damage? Ive never had this happen to me personally but have collected many rebuildable woofers with this type failure. How do i fix this with reusing the original coil and making new lead wires up to the spider connection? Thanks for any info. Id like to replace the spiders with nice new units and reuse the coils that look new just have no connection leads. Also none have heat damage noticeable from shorting or high power or extreme clipping causing the damage to the wire, its just ripped away, the leads thru the spider are still like new with casing all the way to the speaker terminals on the baskets so its not from melting
Over excursion can pull the copper in two. At least if I'm understanding your question correction, Had this issue one some JLW0 when it first came out. Subs looked perfect all the way through the tear down, ended up being broken in two under the glue that holds the cone to the voice coil former.
@@RandomAudioGuys exactly. The little wires that come up the former thing and attach to the spiders leads are ripped apart
One thing i Love about your videos. You don't edit stuff out thank you!
Skar is the poorman's Sundown.
If you only knew. But I do try to leave alot in. Seems no one wants you to know everything no more.
Skar will go out of business eventually or become the next Boss brand at the direction the owner is taking the company. We had alot of shipments bad out of the box and they wouldnt stand behind it. Broken frames from China and after they realized they had a major issue they started putting insurance on them and trying to blame the US shipping companies for the problem. Guy is a real crook.
Random Audio Guy good incite. heard horror stories from different companies. screens purchasing decisions toward the most credible companies. another filter is count how many recone videos and times people say "that stinks". a good judge of how durable the woofer is. the usa line from DD passes this test. great video for tips and tricks.
Gettn custom hcca 15's built. Traded in my blown 18" Kove Armageddon U2's for a discount. Not a lazy audiophile so im thinkn of gettn into this part of audio. Thinkn! :) you make it look SO simple.
How did you do this, I just blew my 12" Kove Armageddon and considering rebuilding
Nice video I need my sundown rebuilt I might try it after watching you
Daniel Brown next time don’t buy the low end subs. Or don’t send 1000 wats to a 500 wat sub. Smoke weed

I gave you the 1k like! Lol. Awesome. And awesome video btw! Im wondering if you have a video on replacing a subwoofer basket? Mine is completely broken in 2 spots and im looking into fixing it. Its a sundown SA-15.
You can contact Sundown for a replacement. They were bought out and I do not know their process since the new owners but it should be purchasable. I know DD offers baskets to us dealers.
@@RandomAudioGuys thanks. I've never taken on a project like this before. I am honestly considering using some JB weld steel stik. Do you think it would hold?
Excellent. I have a pair of blown Pioneer TS-A652F to play with. This will be my first time. I have experience with repairing amplifiers. Should be simple enough. Do you have links for the glue and excelerator?
This means I can buy a refurbished sub that has replacement parts. Sounds like a good investment. Does Alpine R's have repair kits?
Thanks.
Nice! I've always wanted to rebuild a woofer. Keep up the good work
Follow me on instagram @poloqueen_always
Automatic sub and a like! Great video!
Do you still repair subs? I bought a refurbushed JL 13w7 and it has a rattle noise coming from the sub itself.. it looks like it was rebuilt properly but im thinking something with the coil is wrong.. my buddy said it sounds like a "death rattle".. im probably gonna have to get it rebuilt or do it myself huh? Doesnt look hard, but that could also be that youre good at what you do and make it look easy lol
Do you need the recone kit for the exact same speaker or can you get away with one for the same size and specs?
As long as the specs are the same , meaning the gapping of the voicecoil ect... But its not typical that these will line up with another woofers build.
Hey are those stamped steel 110 bolt pattern I need some thats pretty deep for a nice thick double stack motors
Question for you if you can. I have a 12" not great sub but good enough for me. It is a Infinity, came in a set. The sub is in the process of giving up the ghost so I disconnected it and put a 10" polk on it. That sounds fine too but I would like to reclaim my 12" sub rather than buy a new one. Think the problem is with the amplifier part and would like to take the old one out and put in a replacement. This possible?
Check with buildmyspeaker.com they may offer a repair kit for that woofer.
Thanks for that! I will check with them.
@@RandomAudioGuys but that link does not seem to be working...
I have a 10 year old NHT SW10 MK2 with, I think, a sick10" driver and am wondering if you or someone can fix it? Thanks!
Not something I would be able to repair, you might want to try fixmyspeaker.com
We’re are you located I need my 2 15’s redone like that
Hey I have an skar zvx 8 inch. I punch two holes in my foam of my speaker and I tried to fix it but not good. Well please send me some information how I can get my speaker to you for repair
What size voice coil and spider on the 12 inch u rebuilt also do u sell off brand sub parts ?
It was a 2.5 inch. All parts in the video are provided for purchase from DD Audio.
Hey may i ask what country ur in also do u do this for out of country people also does the sub cone foam on outside of basket need replacing if it just has cracks not tears
Is that the same Redline from the late 80s/early 90s? I had a set of 12s and the magnets were like 10" or so and they hit hard. So much they caused my eyelids to blink.
These ones are much better but they have released a new series and its so so. Red candy basket on them so you can tell they are the new ones, Id steer to a higher series.
Hi I'm trying to recall a 12-inch American bass XFL =1222. And it seems they do not sell recon kits for that particular woofer will they have discontinued them. I am trying to get it reconed.Can u do it or can I get the parts to attempt it myself? Thanks
I do not offer the service. I know fixmyspeaker dot com may have the parts, they carry and make things that fit many subwoofers. You might want to try them on the parts.
Will I find for some nemesis 10"?
can the audiopipe 3 or 4 stack be repaired 12 or 15 inch
Love the content(still) but again I think you'd have a high viewer content doing the how to 4th order 6th order and tline. Covering the math the prep the building and design aspects of the more complicated box's. Seems everyone is turning to the 4th orders one note wonder boxes. I think a series of these would bring in tons of views maybe making some change in your pocket on TH-cam's dime
Keep up the great vidz !
I have a set of subs they are power acoustic Gothic where can I get parts to rebuild them or can i
any advice in keeping dd 506d's from tearing up their foam surround?
If you having issue's where they keep doing it then you are over extending them. Use a subsonic filter on your amplifier to stop them from playing super low ranges. And how many are you running and what amplifier.
@@RandomAudioGuys running 4 with a dm 1500 at 2ohms
seem to have troubles locating power acoustic reconeing kits, is there another option that is compatible?
We call them throw away subs for that reason. They are meant to go until they blow then you throw them away. There is no rebuild that I know for them.
Curious my speaker works if i push down on it, would that be the voice coil, or one of them rather
how much would you charge to fix 15 inch mtx audio sub
Do you know anywhere that can repair a 12" Kove Armageddon Subwoofer
Where do I buy all these stuff
Rebuild subwoofer any good ? And break in good does it sound good as one that didn't burn ?
Yes , it is as good as a brand new woofer. Replacing all parts except the metal and the magnet.
@@RandomAudioGuys thanks brother
If I have a freshly rebuild sub I did myself it reads proper ohms and isn’t frozen, but it doesn’t bump or anything what is wrong with it? I am at a loss for what to do?
How close tight are your gap tolerances ? Did it require alot of shimming between the gap and coil ?
@@RandomAudioGuys not sure if my last message went through so, it’s a home built voicecoil, it did not need very much in terms of shimming. Once everything settled it ended up turning out that the aluminum former I used rubs slightly against the center piece in the motor that the voicecoil goes over. You can hear it every single time you actuate the sub by hand although it does not appear to increase the force needed to actuate the woofer up or down. Say the woofer were to be raised by hand it will settle back down in place just fine without any pauses and if memory serves besides the slight noise from the homemade voicecoil rubbing it appears to actuate exactly like it did before. Although I will say the original voice coil did not come apart before when this woofer and it’s sister woofer stopped working. It had some very peculiar symptoms when compared to its sister woofer whose voice coil imploded. This subs voice coil was burnt but did not come apart by any means and still actuated. I sent you the symptoms in more detail over instagram DM’s
Can you use dd coils in Skar woofers?
No, Unfortunetly Skar is just imported with no access to replacement parts because they want you to buy new woofers, That is part of how they sale them cheaper because people will replace them.
Hey, there was an important part that was missed. The part where you thread the coil around the cone. How do we know how much of the coil we need to wrap around?
You need to search for voicecoil repair. I dont cover that in this video as it's best to order a voicecoil
@@RandomAudioGuys Thats my fault. Im guessing that when you buy a kit from somewhere it normally comes with a new voice coil correct?
@@RandomAudioGuys what can I order my parts for my red line 500 series or could I send it to you and you repair for me and tell me how much
And thank you i didnt realize i could rebuild my subs
He's rebuilding a "build your own" sub. You can't do this with every sub unless you're a dealer and can find kits but average subs are so cheap now its not cost effective to rebuild sadly. I would like to tho but this guy makes it look like everyone can just rebuild any sub out there. Is a little more complicated than that I think
questions.....I have an older xe audio (not MA audio) sub that I loved. Still have it. But the coils are shot. Are there other manufacturers that are universal fits that I could fix this with?
Wondering if I can upgrade the thing to better quality instead of just replacing.
Try fixmyspeaker.com/ and see if they can cross reference parts for you. Most subwoofers can be rebuilt using universal parts, they just need the subwoofer information to get a kit that fits it.
Random Audio Guy thanks so much for the reply!
Jeffrey Potter no problem. Hope it helps.
Random Audio Guy I did check their site out. I will have to get some measurements and give them a try. Thanks again!
I did not see you pull out the shims! All seems very easy though.
Do you repair subs for customers
No, it's not a service I offer, I just rebuild my DD woofers
I have a DD redline 612 sub that's making a weird noise on bass notes. My question is could there be any other issues that a recone wouldn't fix? I just don't want to spend money on a recone and the problem isn't fixed.
There are a few reasons this could be happening. One of the things I do find with subwoofers is the voicecoil rub, this will ussally happen at any volume or movment of the subwoofer so even turned down low. So if it were something like that and the pole piece has not slipped then by all means it could be fixed, A subwoofer is dumb, It just moves in and our so not much to be wrong if its not an alignment issue or glue failure so it may be your fix.
@@RandomAudioGuys When I pressed down on the cone I didn't hear anything. It sounds like maybe a loose screw or maybe the plastic under the edge of the spider may be cracked. I'm not sure but I hope my 163 dollar recone will fix the issue. Thanks for the quick response.
Is it possible to jack another voice coil from a different sub to rebuild mine?
Can't really see too much during your installation process.
Any good tips would be appreciated. Thx
Trying to repair a 10" Orion H2-10.4
what do you do wi9th the old copper
We put it in our wire bin and haul it off once a year.
If i bring u a motor and basket that i have built can u get a custom recone for it
I can rebuild most subwoofers. Just depends on what your motor came from or if it was built from scratch. If it was built from scratch I would assume you have all the details needed so we could at least obtain a recone kit.
Could you send me the website to order them repair kit for 500 series dd Red line
Www.ddaudio.com
So how can I do this with say a kicker comp or something? No I don't want to buy a new one Haha I have several laying around that I bought from some one not working. I figured one day I might be able to fix them but have no clue what's wrong with them
Kicker does not offer repair cones for most of their subwoofers, they want you to buy new.
How would i go about fixing a tear in the cone of my sub? The problem is i have a JL W7 so JL wont allow other companies to sell JL parts but fixmyspeaker does make a kit. They guy i bought the sub from (a good friend) says that his buddy fixes torn cones by epoxying them and then spraying bedliner on the entire cone
Your buddies idea ain't bad in some sense, But the amount of weight that adds to the cone destroys its efficiency and changes the parameters completely. Structure wise it would work great. Not seeing the hole size I would typically think a few layers of fiberglass cloth would take care of any hole. Being in the business so long does make me wonder how big this hole is lol, ive seen some dandies over the year. Maybe send me a picture on instagram and Ill take a look and give my best recommendation. Caught you followed me this morning on there so should be able to help you out. And if I remember that rebuild kit is around 250 or so from fixmyspeaker.
How would you stop cone rubbing? I let my L7s sit up a few months, wired em up and now all of sudden I got rubbing.
Cone rub ? I assuming you mean voice coil rub. And if that is the case that usally comes from not having it shimmed right. We use a thin plastic that makes it easy to get super tight gapping.
Random Audio Guy yes you’re right coil rubbing. I’ve never rebuilt the speakers I’m talking about. I don’t know where the coil rubbing came from.
i can take a part that sub and replace the coil and use back all the parts it come with bro. still a good video👍.
Which is great, But as a shop we have to have quick turn around and these kits allow for that. But it is great to see a community that has people who are good in each area.
Hi
I am from india
I need a DD 8 comparable to my SQ hds2108.
The 608 would be most comparable to that woofer.
Where do you get your glue from?
DD sales it.
Awesome. Thanks.
so that voice coil has markings for the placement of the spider or did i miss something
How come you didn't remove the dust cap and just replace the voice coil
DD provides the spider preattached to the voicecoil so it's not an option on their repair kits.
@@RandomAudioGuys thank you random audio guy. I did not know that. Now I feel like a blank. I did not intend to slam you I was just wondering. I just discovered your Channel, and I'm looking forward to getting home tonight to watch more. I've got two JBL 18s and a 18 sound 18 that I had reconed but the voice coil became dislodged instantly by sending way too much power to them unintentionally. The cone spider and everything is good. So much Excursion online The Voice coil. I'm hoping to find a way to replace just that.
Sit on the other side of the table so you don't block the view with your arm
Ive watched several recone videos and I see different opinions or methods when comes to adhesives, I've seen to use rubberized glue on parts to frame and CA glue to and coil joints, It looks like you use the same rubberized glue on the entire build. I'm assuming that's what DD specifies. I've also seen people use regular hardware store locktight brand 2 part epoxy on coil joints. I was going to recone my NVX VCW15 the drop in was $80 but I couldn't get through to them (covid issue I think) , PSI quoted $150 but it was upgraded parts they claimed an increase from the factory 1000w rating to 1300/1500w, the down side with psi was if I was to get a 2nd sub I couldn't without buying one and instantly reconeing it with psi and we'll that would be end up $350+! No thanks. I ended up buying 2 AB XR15s and I bought parts from Lord of base to convert that nvx to a stout 10", I didn't know of them when I originally wanted to fix the NVX. NVX killer sub with great soft parts tough coil BUT half assed glue job had 2 that detached the triple joints but coils were immaculate, so if someone could find a blown one cheap buy a drop in recone and glue it proper and you would have a great sub on the cheap.
Dd offers a rubberized glue for when we do the bigger dustcaps but other than that I'm able to use dd ca glue through oit the entire process and no failures so I stick to what works for me.
I tired a rubberized fix in a jlw7 once and it didnt last a few days so I switched it to dd adhesive and it's still banging a few months later.
How to take out subwoofer in put in new ones
Its a massive hippo xl motor with 10mm spacer and 12 inch basket
Try fixmyspeaker.com/ if I am correct the hippo XL should have soft parts available, have you tried contacting them ?
was thinking about rebuilding these blown ass boss phantom 10s i just bought and got shit out of.. but after all that work.. it's probably just better to spend $130 bucks for 2 new ones
missin your vids....are you ok bro?
Hey I am glad you ask. Im fine thanks. I have a issue with winter and its always been that way and I stepped back from the channel to focus on what worked and what didnt. I am focusing on better quality videos and videos made specifically for the channel rather than trying to shoot work I do for consumers. The fiberglass box did very well that I posted and it was one I made for the channel.
Don't be surprised if you wake up over the next month or 2 and see new videos. Time change and the weather is breaking so I get out alot more and thats when Ill be doing the new videos. You should also see a huge video quality difference.
Again thanks for the check on me and stick with us, youll see the format will be much better and even more detailed.
New sub, dual voice but changed song on high volume, rookie mistake. Have scratching in sub. Brandless build..stuck on repair. I would push these subs... thanks. I'll order, but I use skar amps..they work well, bigdwiz TH-cam dynos, amps.
You should have had a glove, we all know how sharp the coil thread can be
DD specs are half of what they can actually handle.
Epic😂🤣😂🤣easyability
I see you know what your talking about but you can barely see anything your doing If I was a beginner at repairs I wouldn't know how to do half the things you did because I can't see what your doing
Lol I’ll just buy a new one - F all that
This also works with 1500.00 subs where irs more value to rebuild
Roadhouse😂😂
What you're doing is the equivalent of replacing an engine that only has a bad sensor, like a voice coil, instead of replacing what's damaged.
Am I hearing you right? Just replace the burnt voicecoil and save the other parts?
You didnt see us having to dig out the voice coil.
Is it possible to rebuild an eclipse audio subwoofer.
I have an aluminum eclipse that was originally a 4 ohm dvc and was rebuilt to a svc but cant find any recone kits for it.
The sub is sentimental to me and is a really good sub but idk if its a lost cause...
Any info would be great, thanks and awesome video!
