I have a chance at a couple of different speakers, both in excellent shape and priced at $100 a pair, Monitor 10Bs or Snell KIIs. I've heard Monitor 10"s with the Peerless tweets, and liked them, but these appear to have the SL2000s. I would guess the RDO-194 would drop right in, and I would have to redo the crossovers which adds quite a bit to the price. The Snells are a smaller two way with factory matched crossovers that use film caps where needed. I've heard larger Snells and was always impressed by what I heard. I listen to a bit of everything from Classic Rock, Blues and Jazz.
