This system served the stadium for several decades with voice-range audio. However, modern sports fans and associations like FIFA (Fédération Internationale de Football Association) now expect full-range audio for music and clear announcements that are loud enough to be heard over crowd noise. Thus, in 2013, Commonwealth retained Aquila Productions in Edmonton, Alberta to design a new system for the stadium. Lead Consultant Vernon Mason of Aquila retained consultant Dale Fawcett of Orchestral Arts Consulting in Toronto to provide audio modeling and audio system design.
