All Reference Series II speakers feature a redesigned version of Klipsch's famous horn-loaded tweeter. Because high-frequency sounds are more directional than bass frequencies, it's especially important to target them right toward your ears. Klipsch places their titanium tweeter inside a flared opening, known as a "horn," which disperses the highs evenly across your listening area in a 90°-wide, 60°-high pattern. With their Series II speakers, Klipsch has redesigned the shape and slope of their famous horn enclosure, so your movie soundtracks and music will sound more "open," with improved dynamics and efficiency. All in all, you can count on powerful, "front row" sound that's crystal-clear at all volume levels.
