New Dynamic Balance Designed Acoustic Array

Whether upgrading your home theatre setup with an advanced Atmos configuration or enjoying music, Dynamic Balance ensures a rich, clean, full-range sound no matter what you’re listening to. This patented technology analyses 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

Polk's newly designed Terylene dome tweeter features curvilinear formers that extend response and lower resonance. Its 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 so it feels like your 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 fibre 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 Polk's patented design that smoothly transitions the air flow from the speaker’s port into your listening area. It also extends the overall bass port, providing greater surface area to eliminate turbulence and distortion, for bigger, more musical, deep bass impact. Plus, it offers 3dB more bass response output than a traditional port.

High Sensitivity and Maximum Compatibility

Works with the most modestly-powered amplifier or receiver. Whether you’re connecting them to the newest digital processor, or your vintage rig, you get sound reproduction that’s spacious, clear, enveloping, and realistic. Plus, it’s compatible with latest Dolby and DTS surround sound technologies.

Anti-Diffraction Magnetic Grille

Computer modelled for a precision fit and enhanced good looks - and made to minimise sonic interference.

Dual Gold Plated 5-Way Binding Posts

Perfect for easy setup, they ensure the most direct, efficient, and loss-less connection possible.

Quality Crafted Cabinet Design

Strong, rigid and acoustically inert enclosure reduces unwanted internal standing waves for less audible coloration. And non-resonant Meddite MDF construction, with extra bracing and minimum thick baffles, ensures a more lifelike sound.

American Modern Styling

Curved edges offer a sensual yet powerful look that fits with any home decor - available in a stunning black washed walnut finish or classic brown walnut.
