I just got off the phone with Duane at RBH and he didn't have the model number off the top of his head, but said if they're covered in a sock then they're pretty old. Like 90's old and predates the aluminum drivers. Speakers from that era also had foam surrounds and a good chance there could be dry rot. Sounds like a hard pass. He said I could send him an email and he'd dig up what info he has, but knows there wouldn't be anything on the site anymore.
