Polk ES55 Signature Elite

Experience movies, music, and games in high-resolution, room-filling cinematic sound with effortless bass. The powerful ES55 floorstanding speaker from Polk is Hi-Res Audio certified and features an acoustic array with dynamic balance, precise crossovers, and Power Port technology for enhanced bass. The Hi-Res Audio certified Terylene dome tweeter of the ES55 delivers crystal-clear highs (40+ kHz) for high-resolution music from services like Apple Music, Tidal, Amazon Music HD, Qobuz, and Spotify HiFi, as well as soundtracks from the latest Ultra HD movies. Thanks to the dynamic balance polypropylene woofers and the cascading 2.5-way crossover array of the Signature Elite ES55, you will experience a seamless, realistic soundstage, regardless of your listening position. Polk's patented Power Port design ensures higher performance and smoother airflow, resulting in more power and less distortion compared to speakers with traditional bass reflex openings. Combined with the two 6.5-inch woofers of the ES55, this means effortless bass that resonates within your space.
