Since I always have questions with this stuff, I just picked up my new center channel speaker today, a Paradigm Studio CC-590 and I need to adjust the crossover on my 990. Two questions, what would be a good crossover frequency for this (currently at 60hz) and also, would I be better served with leaving it as a small or large speaker? My front speakers are Studio 100's and I have a Servo-15 subwoofer. I also have yet to update my 990 to the latest firmware, I may try that too.

Thanks in advance.
