Hello all. I have a home theater with paradigm studio 60's, cc-590, adp-590s, and the servo-15. I have been used to hearing those and now I want to upgrade my living room. Currently there are 2 fronts and 2 surrounds that are in wall, which I don't really have knowledge about. I would like to add a center and subwoofer to make this setup complete. I cannot decide between the CS2 center channel and the csi-a4. The subwoofer I am looking at is the PSW505 or the PSW10. Whats your guy's input?
