Klipsch Reference RS-42 Surround Black Single speaker - Great condition. Retail Set was $499 About the Klipsch Reference Series RS-42 Here's your ticket to thrilling movie effects. The Klipsch® RS-42 surround speakers feature two sets of drivers angled 90 degrees apart from each other. This clever design delivers ambient effects in a full 180-degree arc, for a diffuse soundfield that completely envelops the listener. It also allows these speakers to deliver great sound even if you place them in less-than-ideal locations. You'll enjoy dynamic surround sound that enhances your movie-watching experience, from soft sounds like crickets chirping to the roar of a jet plane flying overhead. Horn technology for dynamic performance The RS-42 uses horn-loaded tweeters. Flared openings in the enclosure project high frequencies toward your listening area and prevent sound waves from simply spilling out in all directions. It's the same principle that makes your voice easier to hear when you cup your hands around your mouth. This horn design brings out details in everything you listen to, while reducing reflections that can color the sound. It also improves dynamics and efficiency, for powerful, "front row" sound that remains crystal-clear at all volume levels.
