Loud humming buzzing sound coming from subwoofer

While watching tv at normal volume, my KLH subwoofer started to make a loud buzzing humming sound. I checked connections and wires, all good. I disconnected and placed subwoofer on table and under light to get better view. I then plugged in power cord and turned it on and same noise occurs. Took speaker out of enclosure and connected it to normal stereo output and it sounds ok. Could this be a power transformer problem or blown speaker? I did'nt think a blown speaker would still sound normal or does it? KLH model HTA 4906 six speaker surround sound system, powered subwoofer

    connections are right, it is RCA. Tried different outlet and still same noise. I am starting to think it is a blown speaker, just not sure. Is there a way to test it ?

That sounds like a bad plate amp. You may be better off getting a new sub if that is the case -it will cost more to repair than to get a used one from Craigslist.

Check the back side of your equipment. You may have be picking up hum because wires (power, speaker, etc) are placed, or fell, on top of the receiver. If they are, try rearranging things to be as uncluttered as possible, and not on top, or against any A/V equipment.

Make sure you have the speaker connection right if you do then it is a ground problem try plugging it in a different outlet

I have a Rowe R80 jukebox and after moving it it has no sound through the speakers I am in New Zealand


Well, in addition to all the fine suggestions that are here, I would like to add the simple and easy things that may have happened during the move.

IF YOU ARE NOT GETTING A LOUD POP WHEN THE MACHINE IS POWERED ON.......

1) Make sure that the wires on the terminals below are still connected to the screws. There is one ground and one each for left and right. The lower the tap the lower the (max) volume of the jukebox.If they are not connected there will be no sound.

There is a jumpers on the terminal strip where the volume control connects. Make sure that these connections are correct and tight. Also make sure that the jumpers did not fall off.

If you are getting the loud pop in the speakers when the power is turned on .....

Check the plug on the side of the mechanism, just below the back of the tone are.(looks like a little tube socket) Check to see that it is connected to the mech and the CORRECT PLACE on the amplifier. It mat be possible to have this end in the wrong place. bf77613e-82a3-4e37-b8fe-cc80f4d4dbcb.jpg

Check all all your connections against the pic.

I hope this was helpful.
