Hi-Res Certified Audio Performance

Maximize your experience of soundtracks found in the latest high-resolution movie formats along with music streamed over services like Apple Music, Tidal, Amazon Music HD, Qobuz, and Spotify HiFi. Signature Elite’s Hi-Res Audio certified, Terylene dome tweeter features curvilinear formers that extend response beyond the range of human hearing (40kHz+). The tweeter’s ultra-high frequency response combined with its powerful, low resonance ceramic motor structure, enables the Signature Elite ES30 to deliver crystal-clear, highly detailed sound with the energy of live music.

Dynamically Balanced, Three-Driver Acoustic Array with Phase-Optimized Precision Crossovers

Whether upgrading your home theater setup with an advanced Dolby Atmos or DTS:X configuration or wanting to enjoy music from the latest hi-res streaming services, Signature Elite ES30’s Dynamically Balanced, three-driver, acoustic array ensures a focused dialogue channel that blends seamlessly with other Polk Signature Elite speakers. You’ll experience an immersive, lifelike soundstage no matter what you’re listening to or where you’re sitting in the room.

Exclusive Dual Polk Power Port® for Effortless Bass and Full-Frontal Impact

Most conventional center speakers are narrowly tuned to reproduce voice dialogue. But in most film and tv content, the center channel carries as much as 75% of the audio: voice dialogue, music soundtrack, sound FX and more. ES30’s Dual Polk Power Ports enable louder, lower, and cleaner bass from a smaller speaker enclosure which means you’ll hear the full-range sound and more importantly feel the dramatic frontal impact that the director intended.

Built for Pure Sound

Gold-plated five-way binding posts ensure the most direct, efficient, and lossless connection possible. A strong, rigid and acoustically inert enclosure reduces unwanted internal standing waves for less audible coloration. Nonresonant, critically damped Medite MDF construction ensures low distortion for a more lifelike sound. Plus, the ES30’s anti-diffraction, magnetic grille minimizes sonic interference.

Five Decades of Speaker Engineering, Backed by a Five-Year Limited Warranty

The Signature Elite Series is the culmination of five decades of Polk’s premium speaker engineering (Est. 1972) and were designed at our original facility outside of Baltimore, MD. We rely on our patented Dynamic Balance Array process to eliminate electro-acoustic and mechanical issues before they become a part of the finished speaker. We’re so confident of this process, that we back the Signature Elite ES30 with a limited five-year warranty to ensure you years of listening pleasure.


Modern Styling

The ES30’s compact design fits comfortably in most entertainment consoles and their modern, bold look will make a statement with any home décor—available in stunning black or elegant white-washed finishes.
