ES15’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.
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 ES15’s 5.25” woofer, that means effortless bass you can feel.
You’ll experience a seamless, lifelike soundstage no matter where you’re seated thanks to Signature Elite ES15’s Dynamically Balanced speaker array with phase-optimized precision crossovers.
ES15 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.
ES15 is designed for you to hear pure sound the way the director, producer or artist intended.
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.
The ES15’s anti-diffraction, magnetic grille minimizes sonic interference and can be easily removed to provide a striking look.
Gold-plated five-way binding posts ensure the most direct, efficient, and lossless connection possible.
