Polk Audio CSi A6
Centre channel speaker (Cherry)
Our take on the Polk Audio CSi A6 by Crutchfield's Loren Barstow
Enjoy detailed sound from this solidly built center channel
The Polk CSi A6 anchors clear, crisp movie dialogue to your TV screen and delivers thrilling special effects, thanks to its advanced driver technology and solid construction. Polk carefully designed the woofers and tweeter using laser testing to help identify and eliminate resonance points. The acoustically inert MDF cabinet fights internal vibrations that can compromise performance. It all adds up to smooth, accurate sound with DVDs and multichannel music sources. And a real wood veneer finish gives the speaker a warm, refined look, making it an attractive addition to just about any room.

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.
Polymer Composite Woofers: The speaker features two 6-1/2" polymer composite woofers for smooth wide-range response with low distortion. For high performance durability, each woofer uses a butyl rubber surround and an acoustically inert stamped driver basket.
Silk/Polymer Tweeter: The speaker has a 1" silk/polymer dome tweeter that provides clear, detailed highs. The tweeter uses a heat sink on the Neodymium magnet for superior heat dissipation, power handling and reliability.
Mylar Bypass Capacitors: Mylar bypass capacitors in the speaker's crossover network extend high frequency response and improve detail and transparency.
Frequency Response Note: The overall frequency response is 45Hz-27kHz and the -3dB frequency response is 55-26kHz.
Acoustically Inert Cabinet: The speaker cabinet features all-MDF construction with extensive internal bracings that virtually eliminate sound-muddying resonance.
Acoustic Resonance Control (ARC): Internal cabinet resonance can impart a "thick" character to voices. Polk's patented Acoustic Resonance Control port system overcomes this problem. In addition to the Power Port venting system, the speaker has a front-firing port that is tuned to suppress the internal cabinet resonance, resulting in smooth, natural midrange reproduction.
Power Port Venting System: The speaker has two rear-firing Power Port vents built into its two-piece back plate for precise deep bass response. This venting system allows air velocity to slow gradually, vastly reducing air turbulence, and delivering greater bass efficiency than conventional ports. The center channel speaker also features a front firing port for added efficiency and bass response.
Anti-Diffraction Grille: The floating anti-diffraction grille minimizes grille diffraction for spacious, 3-dimensional imaging.
Dual 5-Way Binding Posts: The speaker has two sets of gold-plated 5-way binding posts connected by gold-plated jumpers. Using the dual 5-way binding posts, you can bi-amp or bi-wire the speaker. The gold-plated 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.
Reversible Design: If the speaker must be positioned below ear level, you can turn the cabinet upside down, allowing the drivers to fire upward.
Adjustable Kickstand: The speaker features a unique Adjustable Kickstand for secure balance on shallow-depth TVs and monitors.
Magnetically Shielded: The speaker is magnetically shielded, allowing you to place it on your television without distorting the picture.
