REAL WOOD, REAL HIGH PERFORMANCE Why settle for vinyl speakers when you can have the warmth and beauty of real wood at the same price, with speakers from the RTi Series. They are wonders of industrial design: real wood, radiant with metallic highlights and racing car lines. Classic Polk performance in a design that speaks to today's high-end home décor. True performance art.

INNOVATIVE DESIGN

Anti-Reson ant Enclosure Cabinet resonance can ruin the sound of an otherwise well-designed speaker. You don't want to hear your speaker cabinets humming along with the music (they don't even know the words), you want to hear the uncolored sound launched by the drivers and tweeters. We take special pains to make sure that Polk speaker cabinets are resonance-free. All wood cabinet Polk Audio loudspeakers are constructed of inexpensive low-resonance MDF instead of the cheaper and more resonant particle board used by many competitive speaker brands. RTi Series Speakers feature additional anti-resonance strategies, like asymmetric braces.
