Query: not very good anymore...

I bought these speakers about a year ago, and they worked SUPER well until I packed them up to move. From the point that I unpacked them they made a consistent (and loud) crackling noise that really effects the sound of the music. Not only that, but now I am unable to make the speakers go any louder than low volume. These started out well, but with a little stress on them they completely crapped out.
