A close friend of mine has a set of ancient JBLs. They are currently in storage 3,000 miles away in Seattle, so she is not sure of the model number. She thinks they are L110s, fairly large bookshelf speakers manufactured more than 30 years ago. They worked great until she had to put them in storage. Then, and I'm roughly quoting here, "the foam rings around the metal edge of the drivers disintegrated," probably from lack of use. She is emotionally attached to their sound and the solid walnut cabinets. Are these fixable, and, if so, by whom and at what cost? Could a reasonably proficient handyman (i.e. me)expect to locate the parts/materials and fix them? Don't tell me to advise her to get new ones. Remember I said, "emotionally attached."
