One of the major innovations solved the problem of how to provide low frequencies (bass) evenly to every seat in the arena. Low frequencies canbe very problematic, especially in huge rooms such as the arena. The JBL Custom shop developed a new, Precision Directivity™ technology that effectively allows the low frequencies to be "steered" at specific areas of the arena to assure even bass coverage throughout. These speaker clusters can be seen at four locations within the arena.
