I'm not sure if this sub is constructed the same as my SWS 1022D, but I dicovered that the plastic ring to which the web is attached was loose and buzzing (rattling) against the basket.
I haven't found a fix for it yet, but am confident it can be repaired.

You may have the sub wired wrong. The type r is a dual voice coil sub if I remember correctly. double check your sub wiring and be sure to leave positive feedback or I don't get paid! Here's a handy link to understand how it all works. http://www.crutchfieldadvisor.com/S-3YusLmJyoD7/learningcenter/car/

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.

Why is the subwoofer making a buzzing sound? Is there a solution?


I have had the same problem with my Sony sub. It sounds like it is picking up electrical noise and would not go into standby when the reciever was off. I rerouted my wires and changed to a much higher quality wire. I was using a very low quality stranded copper with thin insulation to start with.

Subwoofer problem


If you get your system up and running and hear an audible buzz or hum, the first culprit to look at is either the powered subwoofer or your reciever feed at the entry point to your system.

Loud buzzing from Kef PSW1000 Subwoofer


yes. A good idea. Kill power to the sub, then unplug and remove everything from the sub. go ahead and plug it in again and check for buzzzz.
That is test one. if you have buzz still, its the sub assembly. bad luck, but not impossible. If the buzz is gone its one of the signals to the sub. They can produce a buzzz without any signal coming from your stereo equipment. Replace the feed line, enjoy! BTW...Kef sure does sound clean. good choice.

Buzzing sound from woofer when I plug in


If the woofer works fine when plugged into any other port, I would say that you have a connector on the receiver that has a loose connection or possibly a cold solder joint (poor or broken solder joint). RCA jacks can be stressed quite a lot especially if you use cables that have very tight connectors. The female RCA jack gets wiggled or twisted when trying to remove a cable and this causes solder joints to crack. I would have a look at that connector on the receiver..

Bose acousticmass 15 sub-woofer making a noise


The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.

100watt sub


There is a problem wwith teh power supply or the amp section. Does the noise remain constant or does it vary in volume? The sub should have a level control, does the noise vary with that control?

Sony Active Subwoofer noise


The circuit that should be turning the sub on and off based upon the presence of an audio signal is not working correctly and the sub is trying to reproduce 60 cycle hum. The unit needs service.
