Polk Audio introduces new center and surround sound loudspeakers

Today, Polk Audio announced the complete re-design of their CSi center channel and FXi surround sound loudspeakers. These new products were specifically designed to match Polk's new RTi Series of floor-standing and bookshelf loudspeakers. These new products feature all-new drivers and tweeters and striking new contemporary cosmetics for surround sound speakers.

There are two new CSi center channel models and two new FXi bipole/dipole surround sound speaker models. The two center channel models will be available in Black Oak and Cherry real wood veneers. This marks the first time that Polk center speakers in this price range will be offered in a choice of real wood veneers. The two FXi surround sound speaker models will be offered in Black and White laminate finishes.

These new models feature the latest generation Dynamic Balance drivers and tweeters. The bass/midrange drivers used throughout the range are the same used throughout the new RTi Series "front" models and use polymer/mineral composite cones. The redesigned 1-inch tweeter is the same used in the latest generation RTi Series: a silk/polymer composite dome for smoother response and better detail than the tweeter used in previous Polk center and surround sound speaker models. It features a neodymium magnet, low-viscosity Ferrofluid cooling and a finned heat sink on the back of the magnet for better power handling and reliability.

CSi Center Channel Models

The CSi models are magnetically shielded to allow safe placement next to televisions or video monitors. Both models feature gold plated 5-way binding posts. The CSi5 offers dual inputs for bi-amplification or bi-wiring. Computer designed tweeter faceplates, stand-off grille and baffle-edge radii all contribute to minimizing diffraction for more open and spacious imaging. The CSi surround sound speaker models are available in either Black Oak or Cherry real wood veneer.

The top-line CSi5 center speaker features Polk's patented Power Port™ technology that reduces turbulence at the mouth of the port. Power Port vastly reduces "chuffing" or "port noise" and provides deeper, more powerful bass than could be achieved with conventional ported or sealed designs of comparable size. The CSi5 also features a second port on the front baffle, an Acoustic Resonance Control (ARC) port that is tuned to cancel internal standing waves that would ordinarily distort midrange reproduction. Patented ARC technology gives the CSi5 surround sound speakers unusually clear, natural and detailed midrange performance.

The CSi5 uses a cascade tapered array - that is, one driver plays only bass frequencies, and the other driver covers the bass and the midrange. This technique avoids the "lobing" effects that plague other horizontal oriented, multi-driver center surround sound speakers. The result is broad, even sound coverage for off-axis listeners.
