Delivering an immersive sound experience, the RP-500SA II Dolby Atmos® surround sound speakers can switch from an up-firing immersive speaker for Dolby Atmos Technology, a height speaker, or a rear surround with ease. A new, larger 90° x 90° silicone composite hybrid Tractrix® horn provides incredibly efficient transfer of high-frequency waves into the listening area for crisper, clearer sound. The phase plug and compression molded silicone face ensure smooth frequency response. The exclusive 1" LTS minimizes distortion for enhanced, detailed performance. LTS tweeters are a hallmark of previous Reference Premiere Series, making it a core component of some of the best speakers in the world. The vented tweeter housing reduces standing waves that create unwanted harmonics, resulting in enhanced detail and clarity in high-frequency reproduction. A signature feature on the Reference Premiere series speakers, the dual 5,25" Cerametallic™ woofers have been updated for absolutely flawless sound reproduction, minimum distortion, and maximum efficiency. The redesigned woofer will deliver the power, detail, and emotion you expect from a Klipsch Reference Premiere speaker. The Klipsch RP-500SA II Surround Speakers can also be utilized as an on-wall elevation or surround speaker via its easy-to-use keyhole mounting system - delivering the perfect angle for enhanced sound effects. The RP-500SA II Dolby Atmos surround sound speakers feature a switchable crossover that changes between Dolby Atmos and Dolby Surround modes for optimized performance in any configuration.
