About Polk Audio CSiA4

The Polk Audio CSiA4 is a high performance center channel speaker (Cherry) for smaller rooms and challenging placement situations. It features two 5-1/4" Dynamic Balance drivers, one 1" 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.

Polk Audio CSiA4 Features

  • A unique kickstand assembly that provides rear support to many projection TVs (will not work with plasmas or other TVs with completely flat rears)
  • The proprietary curved, 6-layer DAHLI 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 engineers to design out 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 RTiA 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 causes distortion to ensure clear and natural sound
  • Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference
  • Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options
  • Dual binding posts allow bi-amp or bi-wire connections, for the ultimate in customized high performance audio
