Question about Audio Players & Recorders

Open Question

I have a Sony Model SS-GZR8D home stereo system that is having speaker problems. I think that there may be a torn cone as I hear a loud vibration under the normal sound during high volume. I cannot figure out nor see any way to remove the main speaker grills. I've tried prying along the seam where the plastic front and the particle board box interfaces but it is not giving at all. No visable fasteners are apparent in either the front or back of these speakers. Any help will be appreciated.

SOURCE: Receiver Shuts down at 45 level

Before I bought anything new, I would check a couple of things: 1 - Is there a problem with heat buildup? Receivers can put out a lot of heat, and if it's in an enclosure without adequate ventilation it can cause problems. 2 - Does the receiver have a switchable impedence setting for speakers? If so, make sure that the impedence matches. 3 - Is the speaker polarity correct? Make sure that the + and - on the receiver matches the posts on the speakers. To rule out problems with speakers and connections, you can try disconnecting all the speakers and running the receiver to see if it shuts down.

I am experiencing loud popping and crackling sound at high volume after speaker is warmed up. Speaker cones move smoothly when pushed gently by hand. Sound almost seems to be coming from inside.


Sounds like it could either be the crossover circuit or a distorted speaker cone. The cone is the easy one to check. You need to check that it moves freely at all points. It sounds like you have partly done this, but you just need to make certain you went all the way around the cone checking for free movement.
However I don't think it is the cone, because of the slow way it acts up. That could be the crossover circuit. If you have a look at it and see either an IC or transistor looking parts, then I would have thought it would be one of them acting up - presumably getting hot!
If you can have the speaker outputting sound, with access to the crossover, you could spray these parts (one at a time if there is more that one) with Servisol Freezer spray. You simply wait till the fault develop then spray the suspect part. If it returns to normal you have located the faulty part. If nothing happens, wait till the coolant wears off then try the next suspect.
Places like Maplin stock the Freezer spray.

I was listening to in on full volume a few weeks ago (as I wanted to be able to hear it from the shower!) and it suddenly started making popping noises.


try using other speakers....the suspect is the speakers, maybe the cones are worn out....due to vibrations caused bu full volume

Bought the stereo 6 months ago, now the speakers won't work!!!! Please help!


Hi, when a speaker does not work, you might need to do some troubleshooting tips to know exactly where the problem is .

First you will need to test the speaker cone if it's working properly by using an AA battery and two wires to make sure the cone is working..

Connect one of the wires to the Positive side of the speaker, and the other on the Negative side, And after that use the battery to hear if the speaker cone will make a click sound.

If it doesn't make a click, that means the speaker cone is Bad, you will need to replace the speaker cone,
But if there is click from the speaker cone, that means the speaker is Ok, and you might need to trouble shoot your stereo to be sure if the sound IC chip is Ok in the stereo..

Hope it helped..

If the speakers vibrate especially when the mega bass is on, does that mean that the speakers are blown on my icf-cdk50?


Real low bass is mostly vibration. Anything that has a "mega bass" 'enancement' is cutting corners to make up for bass-reproduction shortcomings. Speakers measuring 2-5/8' have no business reproducing real bass. Blown speakers would be silent. Torn cones from excessive volume might sound like unwanted vibration. Your vibration might be a resonance of the unit's own housing, mounting hardware or something nearby. Try moving it to another location.

These units are not economically repairable. If you like it and you think it's broken you might snag a whole new on on eBay with wise bidding.

I just received these speakers and they have static in them. What so you think the problem is? johnniemcknight@comcast.net


There could be many causes.

Bad socket on the computer
Dirty volume control
Dirt in and on the speaker cone
Speaker cone torn slightly
A wireless device that may be too close to them eg cordless phone (I know my cell phone is going to ring before it actually does as I get a signal from my speakers)

I have a can of "electrical contact cleaner" which I use to see if it fixes the first two items.
2nd and third item can only bee seen by opening up the speakers.
for dirt I use an air can for cleaning computers but not too close to the cone.
For a torn cone I replace the speakers.

Last item is pretty ease just move the offending item to a new location.

Busted cone (i think)


First try swapping the leads on your source, powering the left speaker with the right channel, and the right speaker with the left, if the problem follows, then the issue is with your source, and not the speaker.
If the cone is torn, then try to patch it, using some basic glue and several layers of tissue paper. White Glue, embed tissue paper in the glue, more glue,embed tissue paper in the glue, do this several times building up several layers. Guessing this is a standard paper cone...
Now if you are still having the issue, could be that the woofer is damaged. Look for a replacement.
