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.
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.
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 ES20’s beefy 6.5” woofer, that means effortless bass you can feel.
