The new RTi products feature all-new drivers, tweeters and contemporary cosmetics. The two top towers feature “Power Port Plus,” the latest enhancement of Polk’s patented Power Port ventingtechnology.
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. They Feature all-MDF construction with extensiveasymmetric cabinet bracing for resonance-free enclosures.
All RTi models feature the latest generation Dynamic Balance drivers and tweeters. The bass/midrange drivers used throughout the RTi range incorporate polymer/mineral composite cones. The redesigned1-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-fluidcooling and a heat sink on the back of the magnet for better power handling and reliability.
All RTi models feature Polk’s patented Power Port technology that reduces turbulence at the mouth of the port. Power Port reduces “chuffing” or “port noise” and provides deeper bass. The two topfloor-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” tofurther 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 bassresponse 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.
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 orbi-wiring.
