To any and all who might know better, I am in the market for a pair of bookshelf speakers to go with my Onkyo TX-8270 2-channel receiver rated at 100 watts per channel. I am interested in the Polk RTI A3 and the Klipsch RP-160M or Klipsch RP-600M. There will not be any home theater use for these, strictly for music listening pleasure in a room approximately 15 x 15. The music that would be played would be R&B, funk, soul, rock, alternative, and alternative rock and some jazz at times. No classical. I understand both are leading brands but can someone out there please help to steer me in the right direction. I've heard both brands and still can't make up my mind. This is why I am asking for the help of other audiophiles out there.
