Hi All, I'm in the process obtaining speakers for a 5.1 HT system. I have not yet purchased the center speaker. Due to budget, I am constrained with purchasing used speakers. So far, I have a pair of Paradigm 9semk3 for the fronts, and a set of 7semk3 for the rears. I also have a pair of NHT SW2 subs. Here's the qaundry I'm in. I've read numerous times that one should choose a center speaker that matches the timbre of the fronts. I assume this would be a Paradigm CC-300 which has drivers identical to my fronts. I have had some difficulty finding this model, and have seen a CC-470 that looks really really nice. Its drivers however are updated, and significantly different from my fronts. I believe the CC-470 has gotten very good reviews. Do I dare violate the matching rule and purchase this beautiful CC-470? Any advise would be greatly appreciated!
