The ES30 is designed to serve as the centre channel in a Polk Signature Elite home cinema system. Its dual 5.25-inch drivers provide greater bass and midrange presence than a slim centre-channel design, while the Terylene tweeter maintains detailed dialogue and high-frequency effects. It can be paired with Signature Elite floorstanding or bookshelf speakers and a compatible powered subwoofer for a complete surround system.
