Looking for $450 for a pair of pristine condition LS50's. These still sell for $399 each on Polk Audio web-site http://www.polkaudio.com/home/produc...267&vintage=1. Looking for $250 for the CS350-SL center channel speaker, also like new. This still sells for $449. http://www.polkaudio.com/home/produc...245&vintage=1. These have all had moderate use. All have the black finish. I will consider trade offers. Would be seriously interested in pair of Klipsch KG 4.2/3.2 in trade or partial trade. Also looking for Klipsch center channel. Buyer to pay shipping.
