The Polk Audio Reserve R900 is a versatile height module speaker designed to add immersive, multidimensional sound effects (like Dolby Atmos and DTS:X) to a home theater system, functioning either as a topper for existing speakers or a wall-mounted unit. 

Key Features and Description

• Immersive Audio: The R900 is Dolby Atmos certified and designed to meet DTS:X and IMAX Enhanced specifications, adding a vertical dimension of sound to create a realistic, 3D audio experience without the need for in-ceiling installations.
• Versatile Placement: It features a switch on the back that optimizes performance for its two intended placements:
  • "On Speaker" (Topper): The module is designed to sit directly and seamlessly on top of compatible Polk Reserve Series bookshelf (R100, R200) or floorstanding speakers (R500, R600, R700).
  • "On Wall": The speaker has integrated keyhole slots for a clean, bracket-free wall installation, where its vertical driver array and dispersion pattern are optimized to direct sound to the listening area via the ceiling reflection.
• Flagship Transducer Technology: It incorporates driver components from Polk's flagship Legend series:
  • 1" Pinnacle Ring Radiator Tweeter: Delivers ultra-clear, crisp highs with a wide "sweet spot" and improved high-frequency dispersion.
    • 4" Turbine Cone Woofer: Features a pioneering design that increases cone rigidity without adding mass, resulting in a smooth, detailed midrange and clear bass.
  • Design & Build: The R900 has a carefully cross-braced, sealed enclosure to minimize internal resonances and distortions. It includes an acoustically inert anti-diffraction magnetic grille for a clean, modern aesthetic.
  • Timbre-Matched: It is timbre-matched to seamlessly blend its sound profile with other speakers in the Polk Reserve series, ensuring a cohesive and immersive home theater setup.
