Dynamic Sonic Engin
Exclusive Polk Audio 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.
Beautifully Blended Bass
Cassini oval subwoofer drivers have more surface area than round drivers, dramatically improving their low-frequency response for deep, well-blended bass. The result is sound that seamlessly varies among frequencies for more lifelike reproduction.
VOICE COIL INNOVATION FOR ENHANCED RESPONSE
Innovative overhung voice coil design augments the excursion length for subwoofer drivers, increasing their power-handling capabilities and enhancing bass response. Extended linear motion allows lots of movement in a limited space, eliminating impedance and extending mid- and high-frequency response.
KLIPPEL MOTOR OPTIMIZATION
Laser measurement technology ensures a smooth excursion path at either end of the volume spectrum for uniform performance at high and low volumes.
DYNAMIC BALANCE® TECHNOLOGY
Polk Audio engineers created a way to design out distortion-causing driver and system resonance. That means you hear the sounds created by the artists not the components.
SUPER CELL AERATED POLYPROPYLENE CONE
Aerated Polypropylene has the ideal balance of superior damping properties and lightweight stiffness for more efficient action with less distortion. The durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for purer sounds note after note.
EXTRA SOLID CABINET ENCLOSURES
High-quality, heavy-duty enclosure construction on the back and bottom, as well as baffles with substantial internal bracing and separate interior cabinetry for each driver eliminate cabinet resonances
