Loudspeaker manufacturer Polk Audio announced the complete re-design 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 striking 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. Fit and finish is the best in Polk Audio's history. All-MDF construction with extensive asymmetric cabinet bracing ensures resonance-free enclosures for clean and accurate sound. 

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 ferro-fluid 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 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 two top floor-standing models, 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 for more open and spacious imaging. 

The two larger floor-standing models, RTi10 and RTi12, use multiple long-throw 7" woofers to combine the wide dynamic range benefits of a single large woofer with the tight, punchy, accurate bass response of small woofers. The RTi10's dual 7" woofers have 50% more surface area than a single 8 inch woofer while the RTi12's three 7" woofers have the same surface area as a single 12 inch. Combined with Power Port Plus, these multiple woofers deliver deep high impact bass with speed and accuracy. 

The RTi models are magnetically shielded to allow safe placement next to televisions or video monitors. All models feature gold plated 5-way binding posts with dual inputs for bi-amplification or bi-wiring. 

The new RTi Series will be available in authorized US and Canadian retailers in October 2003.
