I need to "downsize" my speaker system. I currently have the Def Tech towers (BP10), 2002 center, 12" powered sub, BP2x surrounds, but they no longer fit in with everything else....just too big. I like the Def Tech sound, especially the bi-polar towers, but am open to trying something new such as the Klipsch or Paradigm. I am considering the three sub.sat systems named above. My viewing area is 15x20 but the entire room is 15x30 if that helps. I would primarily use this for movies, very little music listening. I appreciate your opinions on this.
