SOURCE: Gain pots are shot

If you have the old pots then the value is usually printed on the side of the pot. If there is no number and you have the pot then you can open them up and using a ohm meter take a reading directly off of the carbon film of the pot. Read from one end to the other. I would expect something on the order of 25K (K=thousand) to about 50K. If you can , get the audio taper style of pot, but in a pinch the linear taper will work. The trickiest part will be to get one that is close enough in size and shape to directly replace the original mounting. Good luck. By the way, in extreme cases I've even used fixed resistors (3 or 6 resistors depending on mono or stereo) to replace a pot and then you just choose resistors that will place the volumn at say 2/3 full.

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.

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:

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.

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.

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
