IPX6 RATED: Perfect for indoor and outdoor installations around the globe, the Klipsch RSM Series is IPX6 Rated. Homeowners will rest easy knowing your new speakers will be water resistant and rainproof for even the most challenging weather conditions. TRACTRIX HYPERFOLD PORT: Klipsch is all about high efficiency, low distortion. Building upon that legacy, we’re introducing the all-new patented Tractrix Hyperfold Port engineered to extend port length for maximum bass power via proprietary five-step folded design. Its increased airflow eliminates chuffing and port noise while providing a greater dispersion pattern for larger coverage areas. DUAL 5-WAY BINDING POST: The Klipsch RSM Series employs dual 5-way binding posts for versatile connection options. 1" TITANIUM COMPRESSION DRIVER: Klipsch outperforms the competition with our all-new 1” Titanium-loaded floating driver bridge with wide dispersion phase plug. Using our patented mumps technology, the RSM Series gives any space extra-wide coverage while providing even and consistent energy for your project. All in all, this means effortless, high-clarity detail. SET SCREWS ON GRILLE: The included set screws on each grille ensures a secure fit between the speaker and grille, while making sure the grilles stay on the enclosures regardless of the environment.
