Product Overview
Great sound for all
Enjoy movies, music and gaming with high-resolution, full-range hi-fi and cinematic sound. Polk’s high-performance ES20 bookshelf loudspeaker features a Dynamic Balance acoustic array, precision crossovers and Power Port bass enhancing technology. Hi-Res Audio Certified and accessibly priced, Signature Elite ES20 fulfills the Polk promise of great sound for all.
High-resolution sound
ES20’s Hi-Res Audio Certified, Terylene dome tweeter provides crystalline highs (40kHz+) ideal for enjoying high resolution music from services like Apple Music, Tidal, Amazon Music HD, Qobuz and Spotify HiFi, along with the soundtracks of the latest ultra-hd movies.
Enjoy louder lows with less distortion
Power Port is a Polk-patented design that smoothly transitions the airflow from the speaker’s port into the listening area to eliminate turbulence and distortion for louder, deeper, more musical bass and a more open and transparent midrange. When paired with the ES20’s beefy 6.5” woofers, that means effortless bass you can feel.
Seamless lifelike soundstage
You’ll experience a seamless, lifelike soundstage no matter where you’re seated thanks to Signature Elite ES20’s Dynamically Balanced acoustic array with phase-optimized, precision crossovers.
Ready for your amplifier or receiver
ES20 delivers spacious, clear, enveloping and realistic sound reproduction from nearly any amplifier or receiver—whether 4- or 8-ohm, vintage audiophile or the latest Dolby Atmos or DTS:X surround sound AVRs.
Built for pure sound
ES20 is designed for you to hear pure sound the way the director, producer or artist intended.
Quiet Cabinet: A strong, rigid and acoustically inert enclosure built with critically damped Medite MDF and laser optimized bracing reduces internal standing waves and resonances for less coloration and distortion of your sound.
Low-interference grille: The ES20's anti-diffraction, magnetic grille minimizes sonic interference and can be easily removed to provide a striking look.
Direct connection: Gold-plated five-way binding posts ensure the most direct, efficient, and lossless connection possible.
