If the remote and power wires both check out okay, the next thing to look for is continuity on the ground wire.

How do you test a Klipsch subwoofer?

To do this, let’s try something called a “buzz test”: Do not plug the other end of that sub cable into your receiver or sub output.

What should I set my low pass filter to?

As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speaker’s lowest frequency response. For example, your speaker’s frequency response goes down to 43Hz. 70% of 43Hz equals 30.1, so you should set the subwoofer’s low pass filter to 30Hz.

The sub does not have to be connected to the Sub Out connection to work. As long as you any some audio being routed to the receiver it will be available on the Left and Right pre-out connecitons. I was recommending you use these by plugging the sub cable into one of them. Hope that helps.
