I use the term "buy" loosely because I just got a great deal on a used Yamaha RX-V675 through my local Craig's List and the guy threw in some Polk Audio speakers. I've never owned Polks before. He didn't have model numbers when I contacted him, so I didn't know what I was getting until I took them home, but this is what I ended up with - two RT55i, a CS245i center and a PSW350 sub. The speakers look to be in very good shape. Decent speakers? Good enough to start an HT for a smallish room? I can find some matching rears on ebay, presumably, if I decide to use these. I won't really have a chance to listen to them for a while, had to stick them in storage for now.
