However, they cover almost the entire venue. We needed to cover the entire area of the stadium. There were quite a few S-200s already installed on the ceiling as a public address system. Because the ceiling opens and closes when this facility is used as a pool, a new speaker system was required for the hockey matches in addition to the PA system. No large amp racks were necessary.
Simple wiring is also an advantage.
Even though we were installing a new system, all we needed was to hook up the signal line and power supply line. It took only two days including installation of loudspeakers and wiring. However, it was discovered that they would block the line of sight to the goal areas for the video cameras, which were set into the center of the speaker cluster installed under the board. In order to get the necessary signal to noise ratio, you need a speaker with high SPL capability, and good frequency and phase responses. You don't want extraneous energy off of the side coverage of the speaker bouncing off any adjacent surfaces such as walls or ceiling - that's destructive energy.
