Crisp dialogue from a solidly built center channel
Crisp dialogue from a solidly built center channel
Complete your Polk home theater system with the CSi A4 center channel speaker. Its advanced driver technology and solid construction work together to deliver clear, distinct movie dialogue and exciting special effects. 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 this speaker a warm, refined look, making it an attractive addition to just about any room.

Driver Technology
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 5-1/4" 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.
Frequency Response Note: The overall frequency response is 55Hz-27kHz and the -3dB frequency response is 65-25kHz.
Enclosure Design
Acoustically Inert Cabinet: The speaker cabinet features all-MDF construction with extensive internal bracings that virtually eliminate sound-muddying resonance.
Port: There is a single port tube opening on the front of the speaker for increased and extended bass response.
Anti-Diffraction Grille: The floating anti-diffraction grille minimizes grille diffraction for spacious, 3-dimensional imaging.
Connections
5-Way Binding Posts: The gold-plated 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.
Mounting Options
Reversible Design: If the speaker must be positioned below ear level, you can turn the cabinet upside down, allowing the drivers to fire upward.
Magnetically Shielded: The speaker is magnetically shielded, allowing you to place it on your television without distorting the picture.

Wife was concerned about seeing speakers everywhere... so i went with in-ceiling MC80's and this center channel. It's slim and tucked perfectly into a top shelf under the TV in our media center. It it right at ear level and sounds amazing. Good range. Crisp highs, clean mids.
