Out with the Bose; In with Polk!!

[Bourne1]

Ok, so I am going out with my Bose AMS 10 system and going to gradually replace the whole system with the Polk Audio RTi-A series. I am going to phase this out and buy the fronts and center channel first.

Then I will buy my rears and subwoofer. The rears will end up changing and become part of my 7.1 system. The subwoofer, I am not 100% sure yet, I am up to hearing peoples thoughts of what subwoofer would pair well with this system; even if it is outside of the Polk family.

The RTi-A1's will eventually become my main Rear L/R surrounds while the RM8's will become the back rear surrounds. My fronts will end up being The A5's.

Any thoughts? Would the RTi-A1's be sufficient enough for a good pair of front channels? I've read some professional reviews about them; it seems that when tested with a wide music spectrum, they had very good range across the board. Just wondering if they would be good as the main L/R's. I would also like to hear your thoughts on the subwoofer. I will say, my room is small, I live in a 1,100 sq ft condo (don't have the exact measurements for the living room; maybe 12x10). Everything will be powered through my Denon 789.
