Looking for what center speaker I want to go with. Originally I was looking at Polk Audio's CS10 model. But don't know how well it sounds. For a bit more money I heard Paradigms Center 3 which sounded good, but have no idea how it compares to the CS10. Does anyone know on these? Also, I am open to suggestion on this. Wanting to keep it under $500 (preferrably under $350). Anyone have any other suggestions that fits this criterea? I have heard that you want to make sure the center speaker is of higher quality, so if this is correct, I want to make sure I am making the right choice.
