Hear More Detail in Music and Movies You Love
ES30’s Hi-Res Audio Certified, Terylene dome tweeter provides
crystalline highs (40+kHz) ideal for high-resolution sound found in
ultra-HD movies, multichannel concert videos, and spatial audio
mixed for Apple Music, Dolby Atmos, or DTS:X.
Dual Polk Power Ports for Effortless Bass
In movies, the center channel carries up to 75% of the audio
content (voices, soundtracks, sound FX), yet most center speakers
are only designed for voice dialog. Polk’s Power Port enables louder,
lower, and cleaner bass from the ES30, which means you’ll hear
and feel impactful full-range sound the way the director intended.
High Sensitivity for Maximum Compatibility
With high sensitivity and 4- and 8-ohm compatibility, the ES30
delivers realistic, powerful and dynamic sound reproduction from
nearly any amplifier or receiver—including the latest Dolby Atmos
and DTS:X surround sound AVRs.
