SOURCE: Loud humming noise from subwoofer

if it is a powered sub you should lift the ground. you can do this by adding a three prong to two prong adapter. you know, like when you go to plug something in and the cord your plugging in has three prongs and the outlet your plugging in to only has two. it doesn't have the hole for the ground so you go get a little grey adapter that has three holes on one side and two prongs or tabs on the other.if that doesn't take the hum out (actually, is keeping the hum from getting in) you have a problem with the amplifier.

im having the exact same problem thinking it was the amp i rigged up a different driver,the amp was fine.i knew the driver wasnt gone and after some looking and testing i got it down to wire mesh(i think a dust sheild,something)inside which was slightly rubbing on the coil,it worked fine loud when it was warm but cold there was bursts of bad feed back noises.

SOURCE: subwoofer clicking noise

Hi I am afraid it sounds like exactly the same problem I had, Namely the PSU(power suplly unit) is failing, This is a common fault (by reading loads of forums) I contacted KEF today about mine and they say the probably wont be able to source any more spares(due to so many having thuis problem no doubt) So I would suggest contacting the people you bought it from,Under the consumer protection act you should expect an electrical item to "Last a reasonable amount of time" .Mine is 3 years old and I do not consider this to be a long period so kick up and you should be entitled to a repair or at worst a partial refund.Look here basically the same Sub.

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.

The subwoofer SP-PWM505 won't turn on.


Make sure its not set to Auto. Also check for a fuse in the back. Unplug the amp side and with the sub plugged in touch the RCA. You should hear noise from sub. Try this last. Some may say this is not good for the sub. Im in the business and never have seen it cause a problem

My samsung plasma tv went out and it just makes a clicking noise and wont turn on i replaced the power board but it still does the same thing help anyone!


It was not your power board, Thought the same on several repairs.Found out it was the main board. The clicking was the tuner relay. I bet you own a SP-R4232. If so,The part you need is BN41-00574A. Also might be under BN94-00669A. Hard to find. Try Shop Jimmy/Or Encompass Parts. Not cheep tho. Hope this info helps.
Have a happy new year. Todd
