New here. I am in the process of upgrading my home theater system. Just added the Arcam AVR 600 and am now looking at new speakers. My room is about 20x24 with 8 foot ceilings. Watch mostly movies,little videogaming on PS3,and hardly any music. Looking to do a 5.1 system, already have a SVS sub. Need fronts, center channel and surrounds. What should I take a look at?Thanks for the info. John
