  • These are excellent speakers. They sound super-clear with accurate full-range reproduction and even a bit of bass.
  • Sound quality is excellent, and they handle transitions between complex passages to more isolated ones faithfully.
  • Great bass response, clear mids and highs. I think these are great for movies/TV and they are perfect for music.
