I assume you're asking what we think about the speaker quality and/or the repair needed? If you asking about the value of the $100 purchase, then this is a D&S section thread. I'd say you bought a pair of speakers that are known for having good sound. I'd also say you should have an easy time getting a replacement driver on eBay. No comment on the value relating to the purchase price, so your thread doesn't get moved by a mod.
I am mostly trying to anticipate what the speakers will sound like. I will be putting a Sony ta-n77es pre amp and amp through them but it is at my parents' house about 600 miles away. just excited
Those are late 10Bs with 6503 drivers You can find them on Ebay or Club Polk. Polk sells new ones but they sound slightly different then the originals. You should be able to find an original for around $25. as the 6503 was used in almost everything SDA wise after 1986 and Monitor 10Bs, RTA 11 and RTA15.
