How does a shielded horizontal Paradigm Studio/40 compare to the Studio/CC for the center channel? I am considering Studio/40s or or Studio/60s for the front with Studio/20s for the side and rear surrounds (driven by a Denon AVR-4802) plus a Paradigm Servo-15 or SVS subwoofer. The center will be about 11 feet from the listening positions which are up to 20 degrees off axis. With a Studio/40 center, would the 40s be better than the 60s for the front? The room is 15 feet wide by 22 feet deep with 8 foot ceiling.
