Anyone familiar with these? I have an opportunity to pick up 8 of them for next to nothing. A few have bum surrounds, bu the rest seem fine. I know some of Advendt's older stuff sounded pretty nice, not sure of the vintage on these. They were used indoors only. Same as ones in this link. Can probably get set of eight for $50.
