I have a Klipsch subwoofer model xw-300d and has been working fine for years and now if hums and makes static noise. I thought i had a bad connection from the rca connection so i disconnected the cable and it makes the same noise with or without the rca connection. Any ideas what i should be looking for to correct the problem. The ground wire from the ac plug is making good connection Thanks Peter L

I want to thank everyone for their input on my speaker problem. I don't think it is cable or connection problems because i changed the wires and i changed amps and i still have the problem. And yes the problem stays with one speaker which makes me think it's a capacitor problem or something to do with the crossover. I Just don't know enough about crossovers to try replacing crossovers or capacitors Would it be worth my while to swap crossovers from one speaker to the other to narrow it down. Thanks Peter L

Yes

I have a pair of heresy speakers about 20 years old and when i go to play a dvd with surround sound my left speaker doesn't work unless i crank the volume up about halfway then the speaker plays fine after that at regular volume. i've rewired the speaker with monster cables and changed the speaker over to a new amp (Mcintosh) 2105 and i have the same problem. Is there something i have to change in the crossover network? Thanks Peter L
