Natural bass
Polk's patented Power Port phase inverter design creates a larger surface area and directed airflow escaping from the cabinet, increasing power and significantly reducing cabinet and bass losses compared to conventional ported systems. In the ES55, light and effortless bass is created by two 6.5-inch woofers.
