Sub repair

Well actually you can repair it your self with geat ease i may add,,

actuall all that can go in the speaker is the coil.. Yep the coil thats all

You will need a coil for it, a dust cap and the cone.
1.) using a knife, cut the cone off
2.) ulsolder the coil from the speaker
3.) resolder the new coil
4.) firmly fit and glue the coil to the new cone
5.) glue the cone to the metal edges of the speaker
6.) glue on the dust cap..
7.) have a beer your done..

You can get the parts at any local electronisc shop, I'd recommend you cut the cone and the coil off and take it with you when buying parts.

One sub not working

Try this....the speaker that is not working, gently work the cone up and down with you fingers. Be careful not to go right thru the cone. One hand underneath(near webbing) and one hand on top over the dust cover. If you hear any kind of scratching, or noise, or it's not "breathing" freely, then the voice coil of that speaker may have overheated, or the speaker has extended above and beyond its range of movement (called excursion). And may as well be blown/dead/fried..however you want to say. I hope this is not the case for you.

How do u disassemble the jl 12w7, the cone is stuck

if the cone is stuck, it is possible because the voice coil over-heated. There is really no way to disassemble the speaker without re-coning it. The thing you can do is manipulate the cone with your fingers gently, and it might release. Be careful. hope this helps.

Dust cover came off of cone on a older JL it blows alot of air.

The dust cover does not need the flexibility needed at the outer edges of the cone. Clear nail polish often works well for dust covers.

Fixing the middle piece of the sub

Hello stoge52,

Many people do their own speaker repairs and it is many times perfectly satisfactory. The folks who do a lot of it are musicians who seem to bang their equipment around quite frequently.

The problem with your JL sounds like the dust cover and not the cone itself, so you are lucky in that respect. Repairing the cone is more involved and it's rather tricky to duplicate the thickness, rigidity, and original elasticity of the cone. It's usually best to simply replace the cone, a process called "reconing". But gluing the dust cover is perfectly acceptable and not much of a job at all. Don't try super glue. It won't work. I'm not sure about rubber cement, though, but I've never heard of anyone using it. Many pros use silicone sealant. Either black or clear looks best for speaker repair. A somewhat better product is a tennis shoe repair product called "Shoe Goo". It's a little lighter and remains more pliable than silicone sealant, making it a better choice for lighter speakers. You can usually find "Shoe Goo" at larger sporting goods stores. If you want to use something that is made especially for gluing speakers, here's a link to a product called "Prosound Loudspeaker Recone Adhesive" and is advertised as the same black adhesive as that used by many major speaker manufacturers. It's $19.99 for 8 fl oz, more expensive than silicone sealant. Is it better? I don't know. But if it were MY JL, I'd probably spring for it.

You may want to gently remove the dust cover entirely from the speaker and make sure that there are not any tears in the cone itself. If there are, you should repair them first.

Also, when you reglue the dust cover, wait a MINIMUM of 24 hours for the glue/sealant to set up and cure properly. If you start the sub thumping before the glue has fully cured, you'll have the same problem again. One other thing, use just enough glue/sealant to do the job. Don't think that more is better. A consistent thin layer on the entire surfaces being joined is best. A gob here and there will not hold for very long.

The alternative is to send it out for repair. And since it is a JL, I would not send it anywhere but JL. Be advised that is not going to be cheap. And it's going to be time consuming. Probably at least 25-50% of the cost of a new sub and probably a minimum of 3-4 weeks, sometimes longer. And don't forget, you'll pay shipping both ways.

Hope this helps.

The spider on my 12' infinity Cappa has detached from the cone. i managed to slide it back up about where it goes,but im not sure what glue or what i should use to get it to stay there

Hi tiffleiffle

I use and recommend the specialist glue for speaker repairs that you can purchase online from here. Great for refixing spider wires,dust caps, foam surrounds. Also get just about any other speaker bit or spre part you could think of. Get your speaker bits from speakerbits
