How do I fix my floor speakers that static and sometimes do not have sound coming out of one of the speakers?

Question

They are Cerwin-Vega floor speakers that are about 20 years old or so. I have taken off the shields' and cleaned any corroded contacts and vacuumed any dust off of them too. The problem isn't fixed. Static worse than ever.

Answer 1

If you are using economy [cheap] speaker wire, then that might be your problem. Try to run the speaker wires as far away as you can from any other electronic device that may be in the area of your speaker wire. Sometimes, cheap speaker wire can pick up signals from other devices [just like an antenna] and create buzzing, static, or sometimes the speakers may "pop" when you turn on other devices that share the same electric path.
Try this:
Disconnect the speaker wire from the back of the speaker and start twisting the wire clockwise. Get it as tight as you possibly can [actually if you have a drill, you can put the speaker wire into the drill, lock it down, and turn the drill on...this will get the wire as tight as possible]. If your problem is severe, this, along with moving your speaker wires away from other electrical devices and power cords, should eliminate most of your accoustical problems.

The problem could also be your receiver [or other power source] which is currently powering your speakers. If thats the case, a new receiver may be necessary.

Answer 2

It could be a loose or broken speaker wire. Get some new wire and try hooking it up with that.

Answer 3

What device do you have playing through them, and with what sort of cable and connectors are they attached with?
