I have KLH KSUB-10AN subwoofer and had to clean

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: cube speakers w/ no subwoofer

I have the acoustimas systrem and the speakers do need the sb. That's the heart of the system.
I dropped my two front cubes and neither work. If you would be willing to sell yours at a reasonable price I would be willing to buy.
Please contact Bose customer support and I believe they will tell yiou the same thing.

Please let me know.
