The Polk Audio Signature Elite ES10 is a compact, wall-mountable speaker designed to add detailed surround sound to a home cinema system. A 4-inch polypropylene driver delivers clear midrange and punchy bass, while a Terylene dome tweeter adds crisp, high-resolution treble. Polk’s Power Port design smooths the airflow from the port, so the sound has more weight than most speakers of this size. It works with Dolby Atmos and DTS:X systems, so it can be used as a side, rear or height speaker, and its small size makes it easy to place.
