Hi guys, Been lurking for awhile and decided to join up. This is a great site and resource. Anyway Im just starting out my HT and I have a couple questions. First I have the Cerwin Vega RE30 floorspeakers. I was wondering if I can use these for my fronts as well as my subwoofer. Second, Does the center speaker REALLY have to match the brand of your front speakers. Thanks in advance.
