Product Highlights

    Delivering Subtle Style And Precision Audio

    Don't miss out on the dialogue from your favorite movie, or miss a crucial piece of your next crime drama show. Without a quality center channel speaker, your home theater system is missing a piece of a larger puzzle. The Polk Audio S30 is here to fill that gap. This center speaker will not only deliver the top–notch dialogue but a wide array of sound quality that you may otherwise be missing. The Terylene tweeter and mica–reinforced polypropylene cones work together to bring not only crystal clear highs but clean and clear bass notes. The washed Black Walnut cabinet is equipped with a Power Port to smoothly bring more airflow through the speaker to allow for less turbulence and distortion, and bring a deeper bass impact to your various music options. The anti–diffraction grille is capable of minimizing sonic interference and the gold–plated 5–way binding posts are simple and easy to use with the utmost in lossless connection. Plus there will no longer be a singular "sweet spot" in your listening room, because the S30 helps to create an all–around immersive surround sound system that will fill the whole room with acoustic excellence.

    The Real American HiFi Home Theater Speaker

    Built to bring the big surround sound theater and music experience into the comfort of your living room, the Polk Signature S30 center speaker continues in the Polk tradition of American HiFi. Featuring Hi–Res certification, a new Dynamic Balance designed acoustic array, precision cross–overs, an anti–diffraction grille, modern cabinet styling and exclusive Power Port bass enhancing technology, you get elevated sound for movies, TV and music in a totally re–imagined design. Polk—expect great sound.

    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 Cascading Tapered 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.

    Wall Mountable

    Featuring built–in keyhole slots, this center channel can be easily wall–mounted, too.

    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.


    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.
