Had the same problem with KLH E-10D Preamped Subwoofer. Afte brief research, I found the problem was with my Pioneer VSX-D509S reciever settings, not the subwoofer. If you have the same reciever, you can go to the pioneer website to download specific model owner's manuals.

Select your Pioneer reciever model and it will give you an option to download the pdf manual. Hope this helps.

Pull the amp out of the cabonet and check the fuse first. Then look for visible brown marks on any of the electronics, which will at least point you in the right direction. If you can solder, you can fix it. Hope this helps. If you need further help, post a comment and I can help you troubleshoot more in depth.

SOURCE: I have a KLH SW-90

I have the same amp. there a two ways to use it: The phono plug inputs are low level, are for use as an amplifier only, and their only output is the subwoofer output. In this case, any stereo satellite speakers would be driven directly from your stereo amp.
The high level inputs are meant to be driven as the same as speakers from your stereo amp. A circuit inside samples the bass and directs it to the sub amp and output. this same circut passes unamplified outputs to the satellite outputs. PM me at moestevens@cox.net if you need further info.

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.

Schematic Diagrams for KLH ASW10-120


After acquiring a fried KLH ASW10-120, I write to the tech folks at KLH and they sent me the upper and lower board schematics. I asked if I could publish them online, and explicitly asked if I could share them on FixYa.com, and they gave me permission to do just that.


Here's the lower board, which has the power supply:

Lightning hit the speaker and now it makes a loud buzzing noise. The fuse looks good, but not sure if it is.


It's very likely that lightning has damaged the internal parts of the speaker. You may be able to get it fixed, but it may cost more than the sub is worth.

I have this reciever and it has alot of static, is it worth fixing as don't know the price . it was given to us. is it worth the money


Static is good - that means the receiver is working. You just need a good antenna to get the radio stations better. It should work with a CD player - connect one hear what that sounds. If it's good, then the amplifier is in good shape.

I have a KLH SW-90 amp. When I plug in the RCA plugs I don't get any sound to the Satelight speakers. Is this a sub amp? Do I need to hook up the high input wires to make the satelight speakers work?

My speaker just rip.. i like to know any subwoofer is ok for replace??


it's an 8 ohm driver. It need to be VERY efficient, around 90-91db @ 1w. Measure the enclosure size LxWxH then divide by 1728. That will give you your cu. ft. internal airspace of the box. Then look for a driver that will effectively work in that space. Shouldn't be too expensive, paper cone, foam surround, 8ohm impedance. Hope this helps
