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.
