MTX 12" 2-Way Professional Loudspeaker (Each) - Black/Silver Logo
Anonymous Posted on Sep 21, 2009

Subwoofer hum -MTX12" connected to a Aiwa Surround sound. No problems first 10 months, then suddenly all the subwoofer will do is humm loudly and not play music. Changed cables, no change, changed where it is plugged into (different circuit) still no change. Don't know if it is a problem with Subwoofer-since it worked for 10 months then suddenly quit or with the Aiwa receiver-not driving it.. Since none of the components (internals) are mechanical I can't try using electronic spray cleaner. House is extremely humid this past summer and most natural materials start to mold within a few months if that helps localize what it could be

I assume this is an active sub. The amplifier has most likely failed. You have proved the signal source is not the problem, well almost if you can sucessfully connect the aiwa sub to another amp then we will know for sure. Usually amplifiers fail with an output device short circuit. The hum you here is the power supply direct on the speaker, I would not leave it on for long or speaker damage may ensue.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise

I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

My aiwa surround sound subwoofer is not working. I can here bass when I touch my finger to its cord however. Just isn't working when I play music.

Hi,You did not give make and model of your Receiver !!!
Was it working before or you have just connected it to the receiver..? All surround receivers have a surround Sound Setup procedure that either Activate or Deactivate the Subwoofer..So,pls check your Sound set up and speaker Connectiions on the back of Ampl?f?er.
If problem continues pls let me know with more detailed description.
Hope this helps! Take care and please Remember to rate/vote us

Have an older (6 + Yrs) VX-10A model, that's worked fine up until now. I recently moved, hooked up the same stereo and surround sound speakers, which worked fine, but the subwoofer made a loud hum as...

Disconnect the input and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.

Loud hHum from Subwoofer

Sounds like the hum might be mains hum caused by the failure of the power supply capacitor(s) in the sub. It/they will be the largest on the pc board. You will find all the details (needed to replace it) on them. If you find more than one replace both.

Acoustimass Subwoofer has a low "hummm" sound when turned on.

Sounds like an inadequate ground wire in the signal cable. You may have to replace the cable between the reciever and bass module. It also, however, may be IN the bass or reciever module.
