The redesigned Reference Premiere series combines Klipsch's signature acoustic expertise with state-of-the-art technology to deliver a new gold standard in premium home theater and hi-fi listening solutions. The new, larger 90° x 90° silicone composite Tractrix ® hybrid horn provides incredibly efficient transmission of high-frequency waves into the listening area for sharper, clearer sound. The phase plug and molded silicone surface ensure a smooth frequency response.

The LTS tweeters are a hallmark of the previous Reference Premiere series, making them a staple of some of the best speakers in the world. The vented tweeter enclosure reduces standing waves that create unwanted harmonics, resulting in improved detail and clarity in high-frequency reproduction.

The two 16.5 cm Cerametallic ™ woofers, characteristic of the Reference Premiere series speakers, have been updated for absolutely flawless sound reproduction, minimal distortion and maximum efficiency. The refined woofer delivers the performance, detail and emotion you expect from Klipsch. Reference premier speaker. The Reference Premiere bass reflex port uses Tractrix geometry and allows for the most efficient and fastest air transfer from the cabinet, reducing port noise for more pronounced low frequencies and cleaner, more powerful bass. Dual input terminals for bi-wiring / bi-amping separate high-frequency and low-frequency signals into different speaker cables, reducing distortion for a cleaner midrange. Bi-amping allows customization with external crossovers when using separate amplifiers. Upgrading to immersive Dolby Atmos sound with the RP-500SA speakers is incredibly easy thanks to simple hidden connections on the back of the speakers. These refined connections reduce the visibility of cables while keeping them in place for better cable management. (connecting cables are part of the package)
