If the rubber surrounds are ok, I'd think this is a steal for these. It used the B300 woofers, B110 mids, and T52 tweeters, all classics. Back in the day, I cut my teeth building transmission line enclosures with KEF B139's, B110's, and the earlier T27 tweeters. The 105's have very nice 3 box enclosures, but as Rick said, they really take serious power to drive them well. There is lots of info out there on the crossovers, maybe even alternative replacement drivers if you need to fix them or want to tinker a bit.
