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 and Qobuz, along with the soundtracks of the latest ultra-hd movies.

Effortless Bass
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.

From Vintage Hi-Fi to Dolby Atmos & DTS:X
