Speaker Problem
 

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

Probably 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.

"Like underwater" is a bit vague. Does something happen to the frequencies, is there any noise added etc. etc.

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.
:)

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 was a quick solution to the 'problem' :yep:

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?

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?
