The Polk Audio Signature Elite ES50 is a high-performance 2-way floor-standing loudspeaker designed for Hi-Fi listening and home theater. It features Hi-Res Audio Certification, supporting frequencies up to 40kHz for detailed highs from high-resolution sources like Tidal and Apple Music. Equipped with a 1" Terylene high-resolution dome tweeter and two 5.25" Dynamic Balance mica-reinforced polypropylene cone woofers, it provides clear highs, articulate mids, and effortless bass enhanced by Polk's patented Power Port technology, which minimizes turbulence for deeper, distortion-free low-end extension down to 38-42Hz. The non-resonant MDF cabinet with anti-diffraction magnetic grilles ensures minimal interference, while dual gold-plated 5-way binding posts offer secure connections. Compatible with 4- and 8-ohm amplifiers, Dolby Atmos, and DTS:X, it's ideal for music, movies, and gaming in stereo or surround setups. Available in Black, White, and Walnut finishes, it's sold individually and remains in production as part of the Signature Elite series.
