SOURCE: 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.

There's an amp inside the unit, most likely the semicondutor that does all the work has failed in it.

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.

SW-910, blown speaker or ? makes rattle/buzz sound. replace speaker and/or change to passive type sw?


i would suggest replacing it rather than fixing. The cost of the repair will be about the same.
if you went to a passive sub/seperate power amp setup you could get a much higher quality unit, but it would cost you considerably more cash.

I have a KLH subwoofer which is connected to my reciever and speakers with speaker wire. It is not connected to an outlet. It has recently started making a buzzing/rattling type sound. Do I need to take...


Yes, probably, if you aren't capable of repair yourself. However, IMHO, a replacement will probably cost less in the long run. I have a KLH passive subwoofer myself. I wouldn't pay for any repair if it failed. Replacements are far too inexpensive.

I turn on my subwoofer and the volume is turned down and it makes a loud buzzing sound, and its not even hooked up to the amp, just pluged in. Thank you, Joel Arntsen


You might have blown the speaker. This happens when you play things too loudly and you ruin the speaker inside. You can test this by playing something with a decent amount of bass and turned up a bit. If you hear like a "rattle" in the sound or like something isn't right in the heavy bass notes, then you definitely blew the speaker out. This isn't a tragedy. They're fixable if you bring them to a place that repairs speakers. But I would definitely test it first by hooking it up and playing a loud song with a lot of bass. Hope that helps a little! Please rate my solution!

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

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.
