Polk Audio Black High-Performance Floorstanding Loudspeaker - RTi A9
Why settle for vinyl speakers when you can have the warmth and beauty of real wood at the same price, with speakers from the new RTi A Series. They incorporate Polk Audio's latest Dynamic Balance Cone Drivers and 1-inch tweeters, with an asymmetric cabinet design that's as beautiful for the way it controls resonance and increases cabinet rigidity as for the way it lends an elegant touch to any decor. The RTi A9 uses multiple long-throw 7-inch woofers to combine the wide dynamic range benefits of a single larger woofer with the tight, punchy, accurate Bass response of small woofers. Combined with PowerPort Plus, these multiple woofers deliver deep, high-impact bass with speed and accuracy. PowerPort bass venting vastly reduces "chuffing" or "port noise" and provides deeper, more powerful, lower Distortion bass than could be realized with conventional ported or sealed designs of comparable size. The result is classic Polk performance in a design that speaks to today's high-end home decor.
