New Dynamic Balance Designed Acoustic Array
Be it upgrading your home theater setup with an advanced Atmos configuration or enjoying music, Dynamic Balance ensures a rich, clean, full-range sound. This patented technology analyzes the speaker’s entire electro-acoustic and mechanical system for improved material selection and more efficient geometry. It pinpoints and eliminates issues that reduce speaker performance before they become a part of the finished product.

High-Resolution Audio Performance
The newly designed Terylene dome tweeter from Polk features curvilinear formers that extend response and lower resonance. It’s powerful ceramic motor structure also lowers system resonance and extend low frequency response for better dispersion in the critical midrange, delivering clear and detailed high frequency response for realistic reproduction of vocals and instruments. Certified and capable of delivering 40kHz to support the latest high resolution audio files to make you feel like being right there in the studio or concert hall.

Custom Mid-Range Drivers
Mica-reinforced polypropylene cones with butyl rubber surrounds, massive ceramic motor structures and high-temperature Conex fiber spiders combine to create drivers of exceptionally high efficiency, for clean, clear bass, better linearity, lower distortion and greater durability.

Exclusive Polk Power Port Deep Bass Technology
Power Port® is the patented design from Polk that smoothly transitions the air flow from the speaker’s port into your listening area. Moreover, it extends the overall bass port, providing greater surface area to eliminate turbulence and distortion, for bigger, more musical, deep bass impact. Additionally, it offers 3dB more bass response output than a traditional port.
