I work at best buy and have finally decided on klipsch speaker. I am not sure to get the SB-2's or Sb-3's as mains. I will get the SC-1 as the center channel. I am also not sure the get an actual surround speakers or just get the SB-1's as the rear surrounds. I will power them with an HK225 if you didn't already know that from my billion other posts asking advice. What do you guys think on what speakers?
