Repair Scott 197B II speakers

[Windows Central Question]

Anyone? Anyone? Anyone have experience with the Scott 197B II speakers? I scored a very nice pair at the dump a few weeks ago. 15 inch woofers, rubber surrounds, one blown tweeter, which is made by Philips, Cabinets are surprisingly well-preserved by the quarts of candle wax (I'm not kidding!) that was melted on them. The wax came right off with a plastic scraper. Wax as a preservative. Not just for jelly anymore. Full 1 inch MDF heavy cabinets. They sound.....not bad. But I suspect that they can be improved. Any crossover re-cappers out there?
