I'm going to replace the woofer surrounds in these speakers I picked up for $50,has anyone had any experience with these at all? I know that they were the house speaker brand for Alberts Hi Fi in Western Australia in the 70s, so they cant be too bad they sold the best audio gear at that time. Its just that I noticed Taiwan on the back of the woofers,but they look to be very well built to me,at least for Chinese stuff from back then. On the back of them it has BD (BD imports) FH.1020 8 ohms,Taiwan,K43TM.Ive posted some pictures from my web cam for what they are worth.
