Looking at Polk R50 ( 2 6.5in. drivers) or Klipsch SF1's (1 6.5in. driver). I can get either of these for about the same price.  My first thought is an extra driver in the polk would be better, what do you guys think?  I thinking that instead of 2 souround speakers, just getting 4 of the floorstanding and using thoughs, will this sound good.  On a different note, i am matching these up with a Dennon AVR-1905 reciever at $450 , the reason being because it has 3 inputs for componet. (ps2, cable box and dvd player)  Do you guys have any other recievers in mind.  Sorry, I am pretty stupid when it comes to audio, i will try and keep up.  Thanks for any help.
