Polk's exclusive dynamic sonic engine design optimizes the midrange driver and the ring radiator tweeter in separate interior chambers for improved transient response, superior imaging and greater horizontal off-axis response. Enhanced, re-engineered ring radiator tweeters extend top-end response for incredible details and realistic imaging. Extended Linear Motion voice coil design helps extend mid- and high-frequency response.

Recalling the Lyre shape and at the same time offering a solution that ensures no internal parallel surfaces, the cabinet is characterized by its curved walls which eliminate internal resonances. The 29mm tweeter with its silk dome guarantees the dispersion of sound, providing a natural timbre yet capable of very detailed performance. The front section of Center also holds 2 active mid-woofers with Curve cones and a baffle set apart by its curved lines which produce a decidedly live sound and perfect integration between the driver and the cabinet.
