The document reports on a system optimization project for Crocus City Hall. It compares measurements from an old subwoofer design to a new design at various reference points in the venue. Charts show measurements for the new and old designs at the front-of-house position and subsequent reference points, assessing the new design's ability to make sound consistent throughout the space.
