It looks like the Polk reps' recommendations vary. I did some searches on the Polk forums. One rep recommended the CSi25. Another recommended the CSR, CSM, and CS1. On
this support page, Polk recommends the CS2 as a match to the R50.
I know that the CSi25 matches the R50 perfectly, and I would assume that the CSR does as well. My question is how much is the OP paying for the CSR? You can frequently find the CSi25 on ebay for $80-90 shipped, and it's probably the same speaker.
Edit: It looks like the CSi25 is
about $70 shipped on Amazon.com through Electronics Expo. The cheapest price I found on the CSR is
$110 shipped from Crutchfield.
