Description

Key Features:
-The proprietary curved enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonances. RTiA9 cabinets are designed for clean, accurate sound.
-The two 5 1/4-inch midrange drivers are housed in their own tuned internal enclosures for increased clarity and lifelike detail.
-Klippel motor optimization 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-modelled, 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.
-Beautiful curved furniture-grade hardwood veneer cabinet finishes, with sleek trim accents in black or cherry.
-Computer-modelled anti-diffraction grilles enhance the good looks whilst minimising sonic interference.
-PowerPort? Plus 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.
-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.
