A strong, rigid and acoustically inert enclosure built with critically damped Medite MDF reduces unwanted internal standing waves and resonances for less coloration and distortion of your sound.
Experience a seamless, lifelike soundstage no matter where you’re seated. Signature Elite ES30’s Dynamically Balanced, three-driver, acoustic array with phase optimized, precision crossovers ensures focused dialogue that blends perfectly with other Signature Elite speakers.
ES30’s Hi-Res Audio Certified, Terylene dome tweeter provides crystalline highs (40+kHz) ideal for high-resolution sound found in ultra-HD movies, multi channel concert videos, and spatial audio mixed for Apple Music, Dolby Atmos, or DTS:X.
In movies, the center channel carries up to 75% of the audio content (voices, soundtracks, sound FX), yet most center speakers are only designed for voice dialog. Polk’s Power Port enables louder, lower, and cleaner bass from the ES30, which means you’ll hear and feel impactful full-range sound the way the director intended.
With high sensitivity and 4- and 8-ohm compatibility, the ES30 delivers realistic, powerful and dynamic sound reproduction from nearly any amplifier or receiver— including the latest Dolby Atmos and DTS:X surround sound AVRs.
ES30 is designed for you to hear pure sound the way the director, producer or artist intended.
Signature Elite Series is the culmination of five decades of Polk’s premium loudspeaker engineering and were designed at our original Acoustic Research and Development facility in Owings Mills, Maryland.
Our goal since our founding in 1972 has been to build great loudspeakers that transport you to the scene of the recorded performance. Later with the advent of home theaters, to make you feel that you’re in the center of the action. We’ve achieved this by constant innovation and by leaving nothing to chance. The result of this 50-year engineering heritage is best-in-class loudspeakers backed by numerous awards, patents, and fans like you.
All Polk loudspeakers are built to last. We rely on a patented Dynamic Balance Array process to pinpoint and 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 Series with a limited 5-year warranty to ensure years of listening pleasure.
With Polk Signature Elite loudspeakers, you’ll enjoy movies, music and gaming with high-resolution, room-filling sound with effortless bass. Hi-Res Audio Certified, accessibly priced, and built to exceed our patented, quality-testing process, the Signature Elite series fulfills the Polk promise of great sound for all.
