Country of Origin:

The CSiA4 is a high-performance center channel speaker for smaller rooms and challenging placement situations. It features two 5 1/4-inch Dynamic Balance® drivers, one 1-inch Dynamic Balance dome tweeter for spot-on imaging, seamless soundstage, and natural sounding voices. With the asymmetric cabinet design, you gain the flexibility to place the CSiA4 above or below the TV and aim it at your position.


3-year manufacturer's warranty


  • The proprietary curved enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonances. CSiA4 cabinets are designed for clean, accurate sound.
  • Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.
  • Polk's proprietary, patented Dynamic Balance technology allows our engineers to design out the distortion-causing driver and system resonances, so you only hear the good sounds.
  • Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.
  • The RTA Cascade Tapered Crossover eliminates the comb filtering and beaming, common to multi-driver speakers, which degrades the quality of the audio and collapses the soundstage.
  • Patented Acoustic Resonance Control® (ARC) technology suppresses cabinet resonance that distorts to ensure clear and natural sound.
  • Beautiful curved furniture-grade hardwood veneer cabinet finishes, with sleek trim accents in black or cherry.
  • Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference.
  • All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.
  • Gold-plated, professional-style 5-way binding posts, for the most secure connection options.
