Product Description

The proprietary curved, 6-layer dahli 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-modeled, injection-molded 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 degrade
