I just won the auction of a pair of Polk S4 speakers. I was in the market for some RTi6 but came across these and got them for $80.49 including shipping. I am hoping that they will be compairable to the RTi6 just an older model. I can't seem to find out any info on these. I would like to find out specs, etc on them.
I sure hope that they are better than the R-15's. I could have gotten some brand new R-15's for about what I paid for the S4. I do know that the S4 has a 1" dome tweeter instead of a 3/4" like on the R-15.
