Speaker s500 speaker only works when you push cone slightly into magnet

Car speaker crackles because of dust or loose metal debris getting into the magnet structure. Just try pushing the cone of the speaker down with your finger if you hear scraping sound you have magnetic debris in your voice coil gap. Is is very difficult to get this out because your speaker magnet is very powerful. But all the same try blowing air with a vacuum cleaner , might dislodge the particle if you are lucky.

I just want to confirm that the solution on another page from francis 8 works perfectly ( http://www.fixya.com/support/t3709832-speakers_stopped_working_cannot ). We have two sets of Creatures in our offices, one had been shelved (by someone less persevering than me) due to this problem years ago and my set started this trouble a few days ago. Troubleshot everything, every cable, setting, combination, spare speakers etc - nothing worked. Opening the offending speaker and pulling back the metal weight behind the speaker cone was the solution for BOTH of our units.
Big smiles all around :-)
Note - When you've opened the plastic shell and loosened the speaker from its mounting, the the big round metal piece/magnet sits within the actual speaker 'cage', slightly behind the speaker cone. It's tight but movable and can be pulled all the way back as far as it can go inside it's housing, away from the speaker cone.
Not sure why it gets pulled forward, but it isn't fixed in position and so could clearly get bumped by dropping the speaker or a reasonable impact of some sort. Once bumped forward it would severely limit cone movement and therefore volume.

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.

Bad news! It sounds like the coil is rubbing inside the magnet of the speaker! There's no cure, when the cone is warped it it knackers it up. Had the same problem some years ago with a Wharfedale speaker. Someone told me you can hit it on the part where the cone joins the magnet -with a hammer!
Anyway it didn't make a bit of difference! And the speaker was chucked.

I fixed a similar problem I was having. It requires a little work.

Take out the four screws from under the broken speaker. Carefully remove the cover, separating the speaker from the base. The two are wired together so don't pull them apart with force. Then remove the single screw, which is much larger the the previous four, and separate the speaker from the top cover.

If you chose you can remove the wires from the speaker, they just snap on, but its not required.

What I found is the speaker issue is not with the wire or the power, but the speaker it's self. On the back there is a big round metal piece. On my speaker that piece was pushed towards the front of the speaker. When I looked at the good speaker, that big piece was all the way back. So I simply pulled it back and presto, instant fix!

I hope this works for you.

If the speaker has been overdriven, it may have damaged the cone surround or damaged the speaker coil, causing it to 'rub' inside the magnet. To check for rubbing, you need to move the speaker cone backwards and forwards by hand and listen where the speaker coil/cone goes into the magnet. It should be silent if ok. If you can heara rubbing or grating noise, then the speaker is damaged. If the output driver on the amp is damaged it can give a distorted sound, which could easily happen if it tries to provide too much current.

Halving the impedance will draw twice the current. You could technically get a 3 Db more power since the peak voltage will remain the same. BUT if the magnet structure is not intended to use that cone design, the magnet difference MAY not give you 2 ohms.

In fact, if the designed magnetic flux were smaller, you could wind up with a 1 ohm speaker.

trying to get that much power is really kind of silly as even 50 watts with efficient speakers will exceed safe levels of sound that will not cause damage to your ears.

As you push an amp up in power, usually distortion will increase as well.

flip the speaker upside down n it should b a hole thats where the screw is a woffer is nothig but a cone n a magnet

Contact MMats Pro Audio at 561-842-0600. They can re-cone it for you, or sell you the re-cone kit. If that does not work for you, contact MWA Speaker Parts in Tuscon - 520-647-7193. They can sell you a re-cone kit, or they can direct you to a speaker repair center near you. A third option would be to contact Sundown Audio in Troutman, NC. They may be able to re-cone it for you.

is the cone damaged..you cannot seperate the cone from the magent without damaging the speaker..what do you mean by stabilize the speaker cone ?
