Regarding the center channel, the Confidence Center is too big for my setup and I am now considering the Contour S CX. Is S CX the next best match other than the Confidence Center?
I too felt the Confidence center is too big for a moderate room size, in this case the best alternative is to get the SCX which many are happy to integrate with their C1s.
The Contour SR's are small and aesthetically fit my design, but they merely go down to 85Hz
If this setup is mainly for movies, then, I wouldn't worry about the rear surrounds. Tonally they will match with the C1s and the sound pressure level in the low end would be taken cared by the subs anyways. If you're into multi-channel music, then I would go higher up depending on your budget.
