Hum on the speakers usually indicates that there is a DC voltage on the speaker line. DC voltage on the output lines would be caused by a shorted output transistor.

I have the Klipsch Sub-10 Subwoofer, and it no longer plays music. Now it hums (vibrates constant) and corresponds (louder or softer) with volume control. Light is home but no one home situation. V


Does the subwoofer have the same hum when the input cables have been unplugged? Many input cables use very fine conductors, which often fail. A bad cable will often introduce a hum and prevent a signal from getting through. If the noise is still present without the input cable(s) connected, then repair options are limited. No schematics are available. There's a daughterboard that has been available, but its failure usually causes the system to die (short-circuit). The cost to repair the amplifier may be close to the cost to replace the entire sub.

Speaker humms only. what causes that?


Incorrect connections or volume settings.

• In powering up, mixer first then amp

• In turning off , amp first then mixer


If hum still persist, without the mixer connected

then speaker amp may need servicing.

Get loud hum from both bose companion II speakers when i disconnect left speaker hum goes away tried most everything else thanks


try swapping the speakers around if the problem still persists either the speaker is faulty
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
be sure to wear an anti static earth strap before touching anything inside your computer
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

Hi, what causes hums from speaker is when there is no ground shield from either the power supply or from the cable you plugged into the socket from the power supply.

So you will need to check that out and replace untrusted cables for connection..

If after doing this troubleshooting exercise, you will now need to test the speaker with another set to be sure the humming sound is not coming from there.

I guess that will Do.

Have a nice day...

Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

Trying to find out why my desk speakers buzz when my monitor is on?


If the computer and the powered speakers are connected to different power outlets then you could have an earth loop. This causes a hum in the speakers, this also apply to hi-fi sound systems.
To fix this problem, connect all the computer components to a power board and plug it into a power outlet.

Getting buzzing sound from speaker but can here sound from them.


You could have an earth loop which causes a hum/buzzing sound.
Is your computer and powered speakers plugged into different mains?
Connecting amplifiers and speakers to different power sockets will create earth loop problems
This can be fixed by using a single power board connected to a single mains power socket, then connecting all the computer components and powered speakers into this one power board.
