I am fairly new to Polk and I just purchased two tsi 400's for the left and right setup. I also have a klipsch 450 sub which I love. Im hoping to evenually build my way up to a 7.1 system. Quite a slow process when your a college student! I am now planning on buying a center channel for my system. I was looking at either the CS20 or the CSI A6. I know that the CSI A6 would be a better quality sound, but I had heard that it's best to stick with speakers that are all in the same series so I was curious what you guy's thought.
Also I was looking at the FXI a6's or A4's vs. the bookshelf speakers in the TSI series for the surrouds and was curious if you had any suggestions.
Any help would be greatly appreciated since I really don't have a oppertunity to listen to most of these speakers myself.
