Polk Audio CSI A6 Center Channel Speaker (Single, Black)
Polk Audio CSI A6 Center Channel Speaker
The Polk Audio CSiA6 High Performance Center Channel Speaker (Cherry) is arguably the most important speaker in your home theater system. It's in the middle of all the action and, more importantly, it's the anchor for all dialogs. If you want to hear what the actors and actresses are saying, buy a good center channel speaker. The CSiA6 is the perfect center piece for a big screen TV or a large room. And it's timbre-matched to the RTiA series speaker so you can build a seamless 360-degree experience.
Its massive dual 6 1/2" Dynamic Balance midbass drivers and 1" Dynamic Balance dome tweeter will dish out explosive sound and crisp clear dialog. It's best paired with the larger tower or bookshelf speakers.

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.
