New 6.5” Turbine Cone Design: Polk developed the new Turbine cone specifically for the Legend series to ensure the natural reproduction of the mid-range, the frequencies our ears are so sensitive to. The Turbine cone combines Polk’s proprietary foam core and the molded Turbine geometry which dramatically increases stiffness and damping, without adding mass, resulting in a smooth, detailed mid-range and effortless bass – hear every detail..
Better Bass by Design with Enhanced Power Port: Traditional bass ports make noise and mask the low frequency bass notes you want to hear. The new enhanced Power Port design smoothly transitions air flow from the speaker into your listening area for louder, cleaner bass while minimizing turbulence, distortion, and port noise. Polk refined their current Power Port technology specifically for the Legend series by fine-tuning the geometry of the port flare. Hear and feel the difference..
