CSi A6 Centre Channel Speaker

  •  

    The centre channel speaker is arguably the most important speaker in your home theatre system. It’s in the middle of all the action and, more importantly, it’s the anchor for all dialogue. If you want to hear what the actors and actresses are saying, buy a good centre channel speaker. The CSi A6 is the perfect centre 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° experience. Its massive dual 6 1/2-inch Dynamic Balance® midbass drivers and 1-inch Dynamic Balance dome tweeter will dish out explosive sound and crisp clear dialogue. It’s best paired with the larger tower or bookshelf speakers.

    Borrowing advanced features such as Cascade Tapered Crossover network from the LSi series, dialogue and speech come through crisp and clear while still having the authority for high impact special effects.

    CSi A6 Features:

    • The unique angled top allows the CSi A6 to be inverted so you can place the speaker below your TV and still enjoy great sound.
    • A unique kickstand assembly that provides rear support to many projection TVs (will not work with plasmas or other TVs with completely flat rears).
    • The proprietary curved, 6-layer DAHLI enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonances. CSi A6 cabinets are designed for clean, accurate sound.
    • Klippel motor optimisation 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-moulded 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.
    • PowerPort® bass venting is 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. The CSi A6 features dual PowerPorts for added centre channel realism.
    • 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 minimising 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.
    • Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options.
    • Dual binding posts allow bi-amp or bi-wire connections, for the ultimate in customized high performance audio.
    • All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
