Crackling sound from Speakers..What is the reason?

[addy]

Hi guys, I am facing a problem. I have installed a pioneer DEH-5090UB HU in my swift. I have installed JBL GTO component speakers in the front and Boston S9(3) 6X9 co-axials at the rear.

Right from the day one, I used to hear a crackling sound from my rear left speaker, the Boston. I took this up with the dealer and after a few weeks, he replaced it under warranty. The new speaker was working fine for a couple of months and suddenly I started to hear crackling noises from it. When I took it back to the dealer, the noises took a break and stopped. Again, after a couple of days, it started back. I told the dealer about this and he said he cannot do anything until he himself hears the crackling noises.

After a couple of days, the crackling noises stopped and they showed up again after a couple of months. Again, it was temporary and it disappeared. Now, after 2 years from purchase, those sounds have started again. The speaker does not have warranty and I have to get it repaired myself.:sad:

Can anybody tell me the reason for the crackling noises and if possible, please suggest a remedy.


Thanks,

Addy

Can be loose wire contacts.

Tweater can be faulty.

Check the bass settings of your HU, i used to have this problem with my pioneer if i kept the bass too high for the speakers to handle. Tone it down a little bit, if you are a bass lover go for a seperate sub woofer.

Also check the settings for the balance of output between front and rear, tweak it a little and see the results.

This could be because of dust particles. Probably what you can try is, detach the Speakers from the parcel tray, play little loud music keeping the speakers faced down for few minutes. It worked in my case.

I asked the dealer to check them and he said it was fine. Maybe I have to get them checked them at a different place.

Tweater can be faulty.

Which tweeter are you talking about? AFAIK, the tweeters come with the component speakers, right? How does it affect the rear co-axial speakers?

I have tested the speakers with no bass at all and still the crackling sound appears

I'll try this sometime. Thanks


Thanks all of you for your responses

Even I faced the same problem with my co-axials. I went one step ahead. I unscrewed the tweeter attachment and then used my vacuum cleaner to suck out all the dust particles out of the core. After, fixing the tweeter attachment back the cracking sound was gone. But, after cleaning also try to device certain permanent solution to prevent dust particles from entering the core. I used speaker grill cloth to cover the speakers.

Cheers!

crackling normally does not occur due to dust

are you using any external amp?

could be the coil... happened to my sonodyne sub...

No external amp. I just have 2 components in the front and 2 co-axials in the back.

I have tried vaccuming over the speakers and it has not helped till now. Is it easy to detach the tweeters from the speaker?

You can try unscrewing the tweeters from the woofer. There will be a screw at the back of the woofer magnet. The sound may cause because of some dust particle between the voice coil of the woofer and the core. You will have to pull the cone outwards and have to listen to any sound causing. You can feel the dust particle (if any) while moving the cone with hands only.

good for u buddy,glad that issue is sorted.speakers mounted facing upwards(on trays and such) do exhibit this crackling,particularly with accumulation of dust.has happened to me awhile before with my pioneer 6x9 in my old 800.another way used to be just play loud,bass heavy music for a while.cleared it up right away.cheers

I am having precisely the same problem - new Pioneer HU, new Pioneer speakers that crackle, but intermitently, not all the time. I checked all the newly installed wiring and connections. I replaced the new Pioneer speakers with new Kicker speakers. I tried turning down the bass. Nothing worked.

I believe the crackling only occurs on the Satellite radio, or AM. It really kicked up this morning, concidentally with today's beginning of a huge solar storm. Could I be hearing the effects of sunspots on a very high-tolerance digital stereo component?

Yes, i agree it had happened with me in one of my old 8" woofer and all i needed was to remove the dust cap and blow air to remove the dust from the coil. Its a specialized job which can be done by any speaker cone replacement shop.

It happens when the moving coil pole grates with the magnet when the dust sits in the air gap and rubs against each other.

Cheers,
Hari.

Apologies for a off the track post. This reminded me of a similar incident. I have a bridge camera which is one of my priced possessions. I take care of it much more than anything else. Once, while the zoom barrel was extended, i was 'playing' around in a sandy ground, with it and all of a sudden it stopped working. I switched it on and the only thing it did was 'Error 9, Restart the camera' (not very sure of the error number). I went to a canon camera dealer and he quoted 3k for simply checking and repairing nominal things. This seemed to me way more than the problem itself. That complete night I spent on internet research. Suggestion were from opening the chasis on your own to, your camera has gone for a toss. Numerous other creative ideas as well. Then I came across a post by a desi munda, who suggested to tap at the bottom of camera, gently for 4-5 times and then try switching it on (@ full camera battery). There was also a disclaimer that it can permanently damage the camera. Again by virtue of being a risk taker, after a very selfish 'pranam' infront of God (which otherwise does not happen quite often :lol I tapped with my complete pug....voila it worked. I have never felt so good about a desi solution, before this.

On another occasion one of my colleague's LCD had gone off. He was quoted 9k by Samsung dealer. After some internet research, I realised that most of the samsung lcds have this problem (can't generalise though) and it can be solved by changing a condensor (let not get into the technicalities). I asked him to go to a desi electronic repair guy and ask him to check if the condensors are working. Dedinately no one was aware if the condensors are the actual culprit, but whats the harm to sound 'I know it'. Guess what Rs 600 and it was done and yes the condensors were faulty.

Long story cut short - Try desi solutions as much possible @ owners risk
