I have to disagree with the first response. Having the speakers out of phase will show up as decreased volume primarily in the lower frequencies and from BOTH speakers. In other words, the system will sound like there is little base or too much treble.

Internal problems with the crossover or a mechanical problem with the actual speaker drivers themselves can cause this. If you can gain access to the drivers themselves, try swapping one at a time to see if the problem moves.

Keep us posted,
Dan

Please

Try reversing the POLARITY of the wires on the speaker that is playing at a low volume (swap wires connected to the + and - terminals of the speakers). This would put the speaker back in phase if it were reverse connected, and provide the expected volume level again.

Good luck!

Vox vth120 valvetronix No sound from left speaker output


Try swapping the Left and Right speakers with the following procedure, observing correct polarity of wires:
[i] Label both speaker leads and speakers first to avoid confusion with restoring to same configuration.
L and R is good enough, masking tape suitable.
[i] Swap entire driver / lead assemblies.
Does left channel still not work?
If so then problem is amp.
If fault now swaps to R ch then amp is ok - problem external.
Return to original L&R config.
[ii] Disconnect leads at speaker ends only (power off).
Swap drivers only so leads are still same L&R but drivers now R&L.
Power up and test.
L channel fault = lead or connector fault.
R channel fault = driver fault.
Return to original L&R config.
With a multimeter:
Check buzzer-continuity of leads + + & - - end-to-end.
Check ohms of speakers closely match specified impedance.

Have you tried cross-plugging the speaker cables (i.e. swapping left and right channels) to be absolutely sure it is the amp ? I have a speaker that needs a fair amount of volume to wake it up, but after that performs well.

My laptop speaker stop working from it self


After reinstalling/installing an Operating System you can lose the Audio Drivers or sometimes they just corrupt.. Try reinstalling the Audio Drivers from the disk provide with your P.C./Laptop. If you no longer have the disk just visit the website of the makers of your P.C./Laptop or Motherboard and download the Audio Drivers from there, after that install them.
Thumbs up please if this works for you, thanks..

Crackling noise coming from 1 channel


sounds like you are picking up some interference first try swapping out the RCA cables you are using to connect that component. also keep your RCA cables away from any 110V AC power lines.

same thing with speaker cables, speaker wire should intersect power lines at 90 degrees and should not run parallel to power lines.

many people use the wires that come with their components. these cables are thin and offer very low performance a thicker higher quality cable with a gold connector will not only better maintain the quality of the signal being transferred between components but will also have better shielding to protect the cable from picking up interference from other electrical components and power lines.


Also should point out that a blown speaker sometimes produces a crackling sound, swap your left / right speakers and see if the crackling sound still comes from that speaker if it does you have a blown / damaged component.
