Features
- 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.
- Klippel motor optimization uses laser measurement technology to ensure a consistent excursion path at either end of the driver's travel for uniform performance at both low and high volumes.
- Exclusive, patented Roth crossovers increase lower-order power handling and smooth the impedance curve, for more efficiency and better high frequency response.
