Dynamic Balance

The Polk Audio Signature S20 2-Way Surround Speakers are equipped with a new Dynamic Balanced designed acoustic array that ensures a rich, clean, full-range sound no matter what you’re listening to. This unique patented technology analyzes your speaker’s electro-acoustic and mechanical systems to improve material selection and geometry. The Polk Audio S20 array pinpoints and eliminates issues that might reduce speaker performance, giving you the high-fidelity sound that doesn’t skip a beat.

High-Resolution Performance

Polk Audio is committed to designing audio equipment of only the highest quality. The Polk S20 bookshelf speakers contain a custom 6.5" low distortion mica-reinforced polypropylene mid-range driver with butyl rubber surrounds, massive ceramic motor structures, and high-temperature Conex fiber spiders for exceptionally efficient, clean sound and deep bass. The 1" high-resolution Terylene dome tweeter in the S20 Surround Speakers feature curvilinear formers that extend response and lower resonance. Powered by a ceramic motor, it lowers system resonance and extends low frequency response range, giving you better dispersion in the mid-range and clear and detailed high frequency response that perfectly reproduce sound. Capable of delivering up to 40kHz to support high resolution audio files, the Polk Audio Signature S20 home audio speakers will have you feeling like you are right in the concert hall.

Deep Bass Technology

Polk’s patented Power Port Deep Bass Technology smoothly transitions the air flow from the speaker port to your listening area. Extending the overall S20 bookshelf speaker's bass port, the Port provides greater surface area to eliminate turbulence and distortion for bigger musical impact and deeper bass. The Power Port offers 3dB more bass response output than a traditional port.

Quality Craftsmanship

The Polk S20 American HiFi Home Theater Speakers were designed in a strong, rigid, and acoustically inert enclosure that reduces unwanted internal standing waves. A Meddite MDF construction with extra bracing and minimum thick baffles bring you more lifelike sound than ever before. The Polk Audio S20 speaker system has gold plated 5-way binding posts that are perfect for easy set-up, ensuring the most direct, efficient, and lossless connection possible. Polk Audio designed the S20 with a Timbre matched styling with the same components throughout to achieve seamless speaker to speaker effects.
