Try sending an Email to RBH ... also like a lot of sock speakers, it looks like the top may come off and the sock rolled down ... if he wants to sell them that bad, he should let you try to roll the sock down to inspect the drivers before you buy.\n\nI 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.
