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.
