Polk Audio CSi5

from polkaudio.com

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!). Or, use the CSi5's Adjustable Kick Stand Prop to balance the speaker on your shallow-depth RPTV.

     The CSi5 features a
     unique Adjustable Kickstand
     for secure balance on today's
     shallow-depth TVs and monitors.
     Dynamic Balance polymer composite drivers for smooth wide-range response with low distortion.
   * Power Port bass venting for superior clean, low distortion bass that you can really feel.
   * Acoustic Resonance Control (ARC Port) technology for more natural midrange reproduction.
   * 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.
   * Dual, bi-ampable 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. (The CSi5 is a truly bi-wire- and bi-amp-able Center Channel Speaker!)
   * 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.
