Polk Audio R30 73242

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion. Composite Woofers: Each speaker has a 6-1/2" Dynamic Balance mineral-filled polymer composite woofer for clean midrange and deep, accurate bass. For a smoother response and improved durability, each woofer uses a rubber surround. Silk/Polymer Tweeters: The improved Dynamic Balance silk/polymer tweeters provide clear, detailed highs. Bass Ports: A front-firing bass port on each speaker gives you extended bass response. 5-Way Binding Posts: The 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs. Carpet Spikes: When the carpet spikes are installed, the speaker height is 34.706". Note Frequency Response: The overall frequency response is 45Hz-24kHz and the -3dB frequency response is 55-20kHz.
