No response from speaker when connected to new Sony amp
SOURCE: Lost instructions
The 'Subwoofer' output on your receiver is used to connect to a powered subwoofer with a built in amplifier. Your KLH speakers use what is called a 'passive' subwoofer, it gets its power from the receiver and then passes the higher frequencies to the left and right front speakers after taking out the low frequencies for the subwoofer. A speaker system with a passive subwoofer is good for casual listening, but a powered subwoofer is required for really hearing low frequencies and rumble in movies. The KLH speakers you have were highly rated in their time for their price. The four satellite speakers and center channel speaker have very good sound compared to the little 'midget' surround sound speakers most people buy today.
Here's how you hook them up:
- The left and right front channels from your receiver terminals should go to the terminals on the subwoofer marked 'From Amplifier'
- Your left and right front speakers are then connected to the subwoofer terminals marked 'To Speakers', they do not connect directly to your receiver.
- Your center speaker is connected to your receiver terminals marked 'Center'
- Your rear speakers are connected to your receiver terminals marked 'Surround'
That should get you up and running. If the bass isn't good enough with the passive subwoofer, you can get a decent powered subwoofer like the Velodyne VX-10 for about $150 and 'kick it up a notch'. Good luck and enjoy....

make sure you have the speaker connection right if you do then it is a ground problem try plugging it in a different outlet
SOURCE: My klh subwoofer has R&L
Yes, you use a subwoofer cable and hook it into the mono rca jack in the back of the sub. or you can use a Y splitter 1 female to 2 males. or if your amp has 2 sub outputs (L&R) then use both. I do believe it's said that if you use the high level input, it's better. I forgot why...
Oh yeah. the difference between the 2 is a high level input allows the currant from the amp to pass through the sub, thus allowing the continuation of wattage to your other speakers.
Low level input is only taking a audio signal from the amp. No power is being sen through the connection.
SOURCE: Have the KLH ASW10-120 Powered Subwoofer and it is blowing fuses
This model has a high failure rate with the power supply board. Typically, power resistors fail, which in turn burns out the big capacitors.
I have not heard of transformers failing though, so it shouldn't be too much to repair it.
Here are the schematics for the unit: Upper board and Lower board

Did you ever find a solution for this problem? I have the exact same thing happening with my KLH subwoofer and I'd love to know how to fix it!

I'm assuming your amp for testing was NOT a subwoofer output. I could be wrong.
Your source is responsible for creating LFE output. Are you sure it's doing that?
Tune an FM station and connect any other active RCA output from the source (like a Tape Out) to the sub
