Hey Marty -
This is a WAY overdue update/response. Thanks for your reply. I did end up soaking the sock in OxyClean and my stepfather refinished the wood tops and bases. I also replaced the fabric underneath and these speakers now look and sound fantastic. Oh, I also had a local audio repair business fix one of the crossovers - one of the coils had come loose. Anyway, just thought I'd update, regardless of how late it is!! Take care,
Ted
