resting

Was listening to some music and suddenly there's some weird popping sound and then no sound came out of the speakers anymore. Did a reset of my com and the sound came back for the left and right speakers. The subwoofer's dead. These speakers had served me well for years. Is it time to get them replaced or is there a chance it's fixable? What would be a good replacement set, given that promedia is a very very old model from what I know.
