Judging by the quality of the woofer, I would highly doubt there is anything worth saving. What is your budget to build a set of speakers? I would spend a couple hundred, I have loads of wood, talent and time for that part, just the knowledge of how a speaker works is where I stumble. I honestly don't know what the appropriate budget would be. They would not be for anything more than casual listening, background music most of the time. I am past the age of house parties, but still appreciate quality.
