Designed by Polk for the flagship Legend Series, the Pinnacle Tweeter features a finely tuned waveguide that dramatically improves the dispersion of high frequency energy, ensuring a broad “sweet spot” and consistent sound in every listening position.
The Polk-designed Turbine Cone was designed for the flagship Polk Legend Series. It is a foam-core injection-molded cone made of polypropylene with turbine geometry that dramatically increases stiffness and damping without adding mass. This results in a smooth, detailed mid-range with three-dimensional imaging that brings music and movies to life.
Polk’s newly patented X-Port consists of a set of closed-pipe absorbers specifically tuned to catch and eliminate traditional speaker distortions, helping create distortion-free, effortless bass.
(Only available on some Reserve Series models.)
PowerPort’s carefully engineered port design smooths the flow of air as it exits the cabinet. X-Port adds a set of closed-pipe absorbers that are specifically tuned to eliminate unwanted cabinet and port resonances. Together, PowerPort and X-Port technologies make the new PowerPort 2.0, delivering cleaner tighter bass and a detailed lower mid-range.
