Product Overview
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 placing the CSiA4 above or below the TV and aim it at your position.  The Proprietary Curved 6-Layer DAHLIÂ
- Enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonances. RTiA1 cabinets are designed for clean, accurate sound.
Klippel Motor OptimizationÂ
- 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 TechnologyÂ
- Allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
Durable, Computer-Modeled, Injection-Molded Butyl Rubber SurroundsÂ
- Suppress unwanted cone resonances for a lifetime of reliable sound.
The RTiA Cascade Tapered CrossoverÂ
- Eliminates the comb filtering and beaming, common to multi-driver speakers, which degrades the quality of the audio and collapses the soundstage.
PowerPort® Plus Bass Venting
- Our patented design for smoothly transitioning the air flow from the port into your listening area, eliminating turbulence and distortion, for bigger, more musical, deep bass impact.
Patented Acoustic Resonance Control® (ARC) TechnologyÂ
- Suppresses cabinet resonance that causes distortion to ensure clear and natural sound.
Quality Workmanship
- 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.
