Opernturm, Frankfurt, Germany

Designed by Frankfurt-based architect Christoph Mäckler, OpernTurm is the latest development by Tishman Speyer Properties, whose last major investment in Frankfurt was the Messeturm – the 257m-high ‘giant pencil’ that has stood at the entrance to Messe Frankfurt since 1991 and is known to tens of thousands of tradeshow-goers from all over the world.

In total there are some 13 racks of TOA equipment, including a whopping 78 VM-3000 units and six SX-2000s acting as master controllers, and over 3,000 TOA loudspeakers. The scale of the project is enormous – with 42 floors of offices in the main tower and a further seven in the low-rise section, plus a conference centre, a casino and other leisure facilities, not to mention a series of themed gardens which connect the buildings together.
