I'm looking into the Polk 6700 or the Paradigm Cinema 70 or 90 series. Looking for a 50/50 mix HT/music and the only reason I have these two left is that the speakers need to be satallites and also silver in color. I can get the Polk for $599 w/o sub, $699 w/PSW303 or the Paradigm 70 for $675 w/PDR-8 or 90 series w/PDR-10 for $799. My dad likes the Polk but Im worried the sub might be lacking, so I suggested the Paradigm (really like the 90 series better.) Room is 18 x 18 and we will be using a HK 330, HK 8385 Changer, and Pioneer 563 if that matters any? Also, any other speakers in that category I should look at (thought about Def Tech 80s and Energy 5.2 but both seem to have no silver color available)? Thanks.
