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.
50 years, hundreds of thousands of speakers, and countless awards later, we are still focused on our mission of giving you the absolute best sound for your money. Great Sound for All.
