I need a center speaker for my system. It's not a high end or high budget system but it sounds excellent so far. It consists of two Advent Loudspeakers (1977) in the front, a Polk Audio PSW-202 sub, two Realistic Minimus-7 speakers in the rear, and a Panasonic SA-HE100 reciever. All of them sound very good but I need a center speaker to complete the system. My budget is $200 max. I was looking at the Polk CS1 (can't post a link but it can be found at the Polk website). Would it be a good match? Is it a good quality speaker? Any other suggestions? Thanks.
