So I recently got a good deal locally on a pair of Polk RTi12 speakers and I need to complete the rest of the setup. I'd like to stay consistent so I'm mainly considering either the CSi3 or CSi5 for the center and RTi4 or RTi6 for the surrounds. So should I be getting the larger options since the RTi12 is a fairly large speaker or does it not really matter?
I guess I never really understood the difference between the big/small center options such as the CSi3 vs CSi5 and CS10 vs CS20. I notice the bigger option usually offers a few more Hz in the lower frequency response but does it really matter much?
