Real Wood, Real High Performance

CSi Center Channel Speakers easily carry the 50+% of center channel info delivered in multi-channel sources; their upside-down aim-able cabinets give you the ultimate in placement flexibility and sound-tailoring for your high performance home theater system.

Acoustically inert 3/4" MDF cabinets, finished in Cherry wood or Black Oak veneers. Turn them upside-down to aim them "up" when your placement requires them to be below your TV or video screen (it's a Polk innovation we pioneered back in the 90s!).

  • Dynamic Balance polymer composite drivers for smooth wide-range response with low distortion.
  • 1" silk dome Dynamic Balance tweeter features a neodymium magnet for clear, detailed highs; heat-sinked for superior heat dissipation, power handling and reliability.
  • Butyl rubber surrounds for high performance durability.
  • Acoustically inert stamped driver baskets.
  • Floating anti-diffraction grilles minimize grille diffraction for spacious, 3-dimensional imaging.
  • Magnetic shielding for safe placement near video sources.
    Mylar bypass capacitors in the crossovers extend high frequency response and improve detail and transparency.
  • Gold-plated 5-way binding post inputs (with wide holes for large-gauge bare wire connections) for the most secure connections and the most versatile wiring applications.
  • Timbre-matched to fit into any Polk Audio home theater or multi-channel music system for a more realistic, more seamless surround sound environment.

Floating grilles compliment the real wood finishes and softened contours of the new CSi Series Center Channel Loudspeakers. Metallic elements add a touch of modern style to these classic Polk Audio high performance workhorses.
