Question about Speakers & Subwoofers
When I turn the sub on it makes this loud humming like noise, all other speakers work fine, I opened the sub up and everything seems fine, nothing blown, any ideas? I have a Harmon Kardon HKTS14 subwoofer with the same problem, although I also sometimes get a screeching "fax" like sound from it as well. I am using the original cables to connect from the receiver (AS630), which are color coded purple. Should I try new cables, since these should be shielded? JE
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.
