S Sigs is correct... however if the wires connecting your amplifier/Avr to your subwoofer ae not connecting properly, this might also happen. First check the connections.. then the capacitors.

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.

Get a ground-loop isolator, it should get rid of the humming sound.

KLH HPS 1100 powered subwoofer. as soon as plugged into AC we get a loud hum from spkr. had unit for 8yrs.


Hum usually indicates a power supply problem. If it has an internal supply you will need someone to check it's producing clean DC. Alternatively if you do open it (beware risk of shock!!) initially visually check condition of /replace any bulging electrolytic capacitors.

When I plug it up it makes a loud buzzing humming sound that's unconteollable with the volume.


Buzzing is usally AC line noise leaking into an un-shielded cable somewhere or a floating ground. If the AC plug is reversable, try that. make sure all audio cables are pluh\gged in tightly at each end and routed away from or at right angles to any power cords and away from other sources of strong magnetic fields like TV's. I've also seen variable track lights induce noise but it's usually minor.

If it still does it with no cables attached it's an internal amp problem.

My subwoofer constantly makes a steady intermittent buzz sound while plugged in, even while powered off.


If it has a 3 prong plug, try a 3 prong adaptor - where only 2 prongs are plugged in. Sub's should not be grounded. If it still makes a hum noise, the amp circuitry may be compromised. Replace the amp with an equal at www.partsexpress.com

KLH subwoofer Model BASSBite V. Has a bad 60Hz buzz


Before you go throwing money at this problem, try to eliminate any external influences like track lighting. I myself am trying to figure out why mine makes a buzz throughout my system when the lights are on. I already replaced the variable light control with no improvement.

Bad cable ground can let airborne electronic noise into the Sub's amp.

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 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.

It is a klh powered subwoofer, which buzzes when plugged in, even though the power switch is set to "off"


Sounds like the grounds are screwed up. Try using a grounded wire for the subwoofer input. If that doesn't work, it sounds like something is internally screwed up, like the power supply doesn't fully power down. I guess besides buying a new amp, just connect it to a power strip where the switch is accesable and shut the sub off with the power supply.
