Polk Audio Introduces New RTi Series

14-Aug-03

Polk Audio announced the complete redesign of the RTi Series product line. The RTi Series is Polk's best-selling speaker line, occupying the ""Better"" position in Polk's ""Good"" (R Series), ""Better"" (RTi Series), and ""Best"" (LSi Series) product positioning strategy. The new RTi products feature all-new drivers and tweeters and contemporary cosmetics. The two top towers feature ""Power Port Plus,"" the latest enhancement of Polk's patented Power Port venting technology. There are five models in the range, three floor-standing and two bookshelf, all offered in either Cherry or Black Oak real-wood veneer finishes. The cabinets feature all-MDF construction with extensive asymmetric internal bracing.  All RTi models feature the latest-generation Dynamic Balance drivers and tweeters. The bass/midrange drivers used throughout the RTi range use polymer/mineral composite cones. The redesigned 1-inch tweeter is a silk/polymer composite dome for smoother response and better detail than the tweeter used in the previous RTi Series. It features a neodymium magnet, low-viscosity Ferrofluid cooling, and a heat sink on the back of the magnet for better power handling and reliability. All models feature Polk's patented Power Port technology that reduces turbulence at the mouth of the port. Power Port is designed to reduce ""chuffing"" or ""port noise,"" and is said to provide for deeper, more powerful bass than could be achieved with conventional ported or sealed designs of comparable size. The two top floor-standing models, the RTi10 and RTi12, feature ""Power Port Plus,"" the latest enhancement in Power Port technology. Power Port Plus uses two ports (one front, one rear) and internal ""plates"" to further reduce air turbulence and increase bass efficiency. A computer-designed tweeter faceplate radius, stand-off grilles, and baffle edge radii all contribute to minimizing diffraction.  The two larger floor-standing models, the RTi10 and RTi12, use multiple long-throw 7-inch woofers. The RTi10's dual 7-inch woofers have 50 percent more surface area than a single 8-inch woofer, while the RTi12's three 7-inch woofers have the same surface area as a single 12-inch woofer.The RTi models are magnetically shielded. All models feature gold-plated five-way binding posts with dual inputs for bi-amplification or bi-wiring. The new RTi Series will be available October 2003.For more information about Polk Audio, visit www.polkaudio.com.
