Hello everyone, i have had my klipsh speakers hooked up to my computer for about a half-year now and i absolutely love them. They worked like a dream the whole time until yesterday when i came home and found that whenever the volume got at all high the sound got extremely distorted. I have always kept good care of my speakers, and I never even take them above half volume. I have the ProMedia v.2 -400 speakers. I have no clue if this is a problem with my computer, the speakers, the connection between the two or what. Someone PLEASE Help me. Thanks, Tyler.
