Polk ES50 Signature Elite

Experience movies, music, and games in high-resolution, room-filling cinema sound with effortless bass. The powerful ES50 floor speaker from Polk is Hi-Res Audio certified and features an acoustic array with Dynamic Balance, precision crossovers, and Power Port technology for enhanced bass. The Hi-Res Audio certified Terylen dome tweeter of the ES50 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 the soundtracks of the latest Ultra HD films. Thanks to the Dynamic Balance polypropylene woofers and the cascading 2.5-way crossover array of the Signature Elite ES50, you will experience a seamless, realistic soundstage regardless of your listening position. Polk's patented Power Port design provides greater surface area and more uniform airflow for increased output and reduced distortion compared to speakers with traditional bass reflex ports. Combined with the two 5.25-inch woofers of the ES50, this results in effortless bass that tickles the belly. The ES50 floor speaker impresses with clear, room-filling, and realistic sound reproduction for virtually any amplifier or receiver—from classic 4 or 8-ohm audio systems to the latest surround sound AVRs with Dolby Atmos and DTS:X.
