Polk Audio CSiA4

RTiA Series High Performance Center Channel Speaker

Key Features

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 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.

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.
