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.
ES55’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.
You’ll experience a seamless, lifelike soundstage no matter where you’re seated thanks to Signature Elite ES55’s Dynamic Balance polypropylene woofers and 2.5-way cascaded crossover array.
Polk’s patented Power Port design provides greater surface area and smoother air flow for more output and less distortion compared to conventional ported speakers. When paired with the ES55’s dual 6.5” woofers, that means effortless bass you can feel.
ES55 Towers deliver 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.
ES55 is designed for you to hear pure sound the way the director, producer or artist intended.
