Customized a cable reel to accommodate two audio lines then installed it, along with another reel for power, for a moving truss on which we hung a Meyer center cluster and two subwoofers. In the Brandeis University Slosberg Music Center, subcontracted to Parsons Audio. Not exactly glamorous, but a crucial part of the project.
Below is a photo showing the subwoofers on top on the moving truss for which we designed custom rigging hardware. Also shown are the center cluster and same of the other Meyer speakers we installed.
