Center Speakers That Give Everyone A Front Row Seat

Your Center Channel Speaker is more than just a dialogue speaker: it must carry over 50% of the information in multi-channel movie and music formats. The CSi30 is engineered to be an affordable high performance Center Channel Speaker, anchoring the action or instruments to your screen with performance that matches that of RTi Series main/front speakers.

The CSi30 features:

  • Poly-composite Dynamic Balance drivers with butyl rubber surrounds for durability and smooth wide range response.
  • 1" silk/polymer composite dome tweeter for clear, detailed highs.
  • The same components as the rest of the Polk Audio RTi Series; they're timbre-matched for a more realistic, more seamless surround environment.
  • Real wood veneer finished enclosure
  • Magnetic shielding for safe placement directly on or near video sources.
    Five-way binding post inputs for the most secure connections and the most versatile wiring applications.
