I was all set to make the short drive to Canada and pick up a Titan/Atom/CC170/PDR-10 package for about $650US, but I was at a party and I heard some Polk RT25i's. Then, I found them on sale for $169 a pair. I can get 2 pair of Rt25i's, CS245i center,and the 10" PSW350 sub for about $850. I can't decide if it's worth $200 more for the Polk setup. Any opinions?
