    Product Overview

    Product Overview

    (1) 1” high-resolution Terylene tweeter for crystal clear high frequency response that perfectly reproduces the latest high-resolution audio files

    (1) 6.5” low distortion mica-reinforced polypropylene cones for clean, clear bass, better linearity, and increased dynamic mid-range

    New Dynamic Balance Designed Acoustic Array

    Whether upgrading your home theater 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 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

    Our 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 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 our 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.

    Two-Way Crossover Array

    Gives you a seamless, lifelike soundstage no matter where you’re seated in your listening room. There’s no more sweet spot—instead, it’s all around you.

    Anti-Diffraction Magnetic Grille

    Computer modeled for a precision fit and enhanced good looks—and made to minimize sonic interference.

    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.

    Timbre-Matched

    Designed with the same components throughout to achieve seamless speaker-to-speaker blending effects in multi-channel systems.

    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.

    Limited Warranty, Built to Last

    Designed in California, engineered in Baltimore and manufactured under the strictest quality controls, it includes a limited 5-year warranty.
