A while back I picked up a pair of S8's that needed a tweeter but were otherwise in great shape. I figured I'd flip them but really liked the sound quality. The Polk engineer (ZSP) did a great job voicing these things. About a month ago I found a CS250s which looked to use similar drivers as the S8. I set it up with my Denon AVR-888 the S8's and a PSW10 for a 3.1 HT system, fired up Lord of the Rings and found out what timber matching means. Wow, it was a wall of sound.
Yesterday I found a pair of S4's at GW for cheap, and other than some paint drippings, are perfect. I think I have found my HT system (though I may look to upgrade the sub though). I just need to run some wires for the surrounds.
