Speaker Problem

[convoy hunter]

Hello,
I 've found an old pioneer hifi in the attic recently but it has a problem.
I start playing music but after five minutes the right speaker starts making weird noises while the left is still playing normally. What is the problem.
If it is something simple like wire contacts or so then what should I do?
Thanks

ThanksProbably some loose contacts. Can you open it easily? If so, check if all wires are still connected.

Also, what kind of noise is it? White noise? A beep?

I have opened it up I will post a pic later but it seems all right.
As for the sound its like its been playing music underwater.

I can't see any loose contacts or anything on the pics you posted, but it might be much further into the device, these pics are just of the speaker itself but there's much more inside the thing than just these two and a half wires and a coil;) Besides, it's not always easy to see. Just to be sure it isn't a loose contact, softly pull on all wires and see if they still stick to wherever they're attached to.

As for the sound its like its been playing music underwater."Like underwater" is a bit vague. Does something happen to the frequencies, is there any noise added etc. etc.

[sharkbit]

Are the speaker wires hooked up with the correct polarity?
There should be some +'s on one of the speaker wires. Make sure it is hooked up to the + on the speaker.
:)

[sharkbit]

Also-
Did you try hooking the speaker up to the other channel to make sure it is in the speaker and not in the receiver?

I glanced over the title of this topic and I thought it said 'Sneaker problem'
As in which sneaker to put on first? The left or the right? (Which made me think of 'Friday'; gotta decide which seat to take) :har:

Forgive my ramblings :DL
Anyway, this 'underwater sound' kind a sounds familiar. Like there's a blanket over the speaker or something? I had this with a speaker years ago, and I can't remember what it was. THough I don't think it's loose contacts, then you'd probably just get crackling noises.
I'm going with DarkFish's view on this; the problem could be inside the speaker. I'd also try hooking it up to the other channel as Sharkbit said, but I think it's inside the speaker itself, maybe the coil is damaged?

I ran Sound Systems for many Bands over the years.

If it is not a channel problem
(You'll know by switching the speakers from left to right)
It's a bad speaker.
They heat up a bit and can cause all kinds of weirdness.
If the switch still shows bad on the right side?
It's internal to the system.

It's internal to the system. It was a quick solution to the 'problem' :yep:

[Sledgehammer427]

playing music underwater...like, kinda has this burbly noise to it?
the noise I'm talking about, just say it out loud over and over, is that the sound you are describing? :O:

but, having run sound for a couple bands for myself, I have to agree with privateer. your connections look okay, just make sure they are connected right to the speaker, positive to positive and negative to negative and so on.

good luck! hope you don't have to break out the soldering iron!

I will try that and repost here.

well I changed sides and found out that it is the amplifier which has the problem.
Now what should I do?

[Gerald]

Now what should I do? Did you locate what is broken or not working in the right way,there may be something simple, not need to be any opaque

I am going to open it up soon.
Can it be dust the problem?

[Gerald]

I am going to open it up soon.
Can it be dust the problem? Could be .. but sounds a bit far-fetched unless it has clogged the cooling element in the amplifier, I had on my Nad amp, a problem, and I blew out the system by playing loud about 150 watts, the amp is 300 watts and it helped in fact if the neighbor who lives 700 yards away was not so happy to hear RnB music .. so close in to ;)

[convoy hunter]

mine problem started suddently.
when I first started playing music with it it was all fine then the next day it just broke down

[Gerald]

[Jimbuna]

Send em to Vendor...he's a real expert...he'll 'fix em' one way or another :O:

[DarkFish]

I'd say check for loose connections inside the thing. (remember, slightly touching is often the same as loose) Sometimes a good ole smack can help as well. If it doesn't, well, what's broke already can't break again, can it?:hmmm:
If you can find none, as Vendor says, do you have any instruments at your disposal? An oscilloscope would be a huge help to determine where it goes wrong.

[convoy hunter]

I opened it up and ...... no loose contacts, no dust everything was fine
and now neither the left speaker is playing.

[Gerald]

What happens when you turn on and off, and how many other devices are connected to your amp, :hmmm:

[convoy hunter]

What happens when you turn on and off, and how many other devices are connected to your amp, :hmmm:
playing for a couple of seconds-minutes and then stop.
Only my mp3 player is connected to it.

[convoy hunter]

could it be the mp3 connection to the amplifier?

[Gerald]

could it be the mp3 connection to the amplifier?Hard to say, but I guess you have a converted input to the amplifier, try to pull it out, and if you have anything else running it instead...

[convoy hunter]

it has an on board radio I will start it up.

[Gerald]

it has an on board radio I will start it up. Yes,good!

[DarkFish]

could it be the mp3 connection to the amplifier?could be, but not likely. The fact that it works normally for the first few minutes makes me think it's got something to do with heating.

Are you absolutely positive it isn't a loose connection? loose connections don't have to look like a loose connection, quite often they actually do make contact (at least with bare eyes it seems like it). Also, "wire" doesn't necessarily have to mean a wire in the traditional sense of the word. It can also mean any other conducting connection between components.

yes yes I am sure.
I am uploading two files now so that you can hear.

[Gerald]

Excellent!

left speaker only http://www.zshare.net/audio/89704157a42869b5/ 2nd file
left to right speaker http://www.zshare.net/audio/897041953e4cbccb/ 1st file

[Gerald]

It's sounds ... definitely a little muffled, you may need to max out the amp a bit, adjust your preferences

Best advice to save you effort and money ? Throw it in the trash. :O:

and time of course

niet, no, όχι, nichts

[Gerald]

niet, no, όχι, nichts But you may have the wrong "type" of music that is played in these two files, put on some weight and volume, of course, highly :O:

[convoy hunter]

But you may have the wrong "type" of music that is played in these two files, put on some weight and volume, of course, highly :O:
then what time of music should I use and what do you mean by weight?:06:

[Gerald]

then what time of music should I use and what do you mean by weight?:06: Like this,many different sections with an emphasis in music :03:

http://youtu.be/sfR_HWMzgyc

[convoy hunter]

and the weight?

[Gerald]

and the weight? Forget it, just an expression to get the weight of what you listen to :yep:

[convoy hunter]

http://www.youtube.com/watch?v=i0YGXhAcXc4 is this enough heavy?

[Gerald]

http://www.youtube.com/watch?v=i0YGXhAcXc4 is this enough heavy? Not bad, but a bit thin if you ask me,I mean more to rock, and RnB

in this file the left speaker is playing fine but from 0:10 the right takes over and the song fades.
if you think that the left speaker is not so good in sound you must know that my mic is not so good.

my father had it when he was 25 now he is 43

[Gerald]

my father had it when he was 25 now he is 43 Well...18 years it may be a bit during that time, but you've used the right frequency to quite recently, when these difficulties came up, you have some other speaker to change with...

[convoy hunter]

Well...18 years it may be a bit during that time, but you've used the right frequency to quite recently, when these difficulties came up, you have some other speaker to change with...
as we have discussed previously the speaker is not the problem but the amp itself.

[Gerald]

as we have discussed previously the speaker is not the problem but the amp itself. Maybe...but..now it is so that it can be both parts, I'm not working with this stuff, but have had equipment for a long time, and different mixing systems as little familiar, I can be ... but send an email to Jimbuna he can certainly give you a few good advice, myself, maybe I would consider changing up myself, if you have that money on new equipment, here is a link to Jimbuna

thanks

[Gerald]

thanks You are welcome, :up:

[DarkFish]

then what time of music should I use and what do you mean by weight?:06:the best music for testing is generally metal, plain and simple. If something plays metal well, it plays everything well. You need a strong bass-, mid- and treble range, and very clear sound, or metal will quite easily turn into noise.

Something fast and heavy with loads of distortion like this would be good: http://www.youtube.com/watch?v=h6pEW9VeABU
