Effortless Bass
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.
High Sensitivity and Maximum Compatibility
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.
