Sound System Design
Whether permanently installed or portable, G-Force designs sound systems that will meet your performance goals at competitive prices.
Perhaps the most important thing to consider when designing a sound system is coverage. Below are before and after maps of sound coverage that we created for Watoto Church in Kampala, Uganda. It helped that they had an extra pair of speakers exactly like the ones already installed, and we were able to optimize the placement and angles of the speakers without ever stepping foot in the building.
Had this been a new speaker installation, we would have modeled several different speakers, and optimized the design even further. Intensive experimentation in the design phase helps to avoid costly mistakes later on.
The platform is on the left. The colored portions of both maps represent the coverage that each speaker system provides, and a 12db window is shown in both pictures for illustrative purposes. Notice in the top map, that a 12 db window is not enough – the grey areas represent areas of the room that are more than 12 db quieter than the loudest areas. Translation: It was really hard to hear the preacher, or enjoy the music.
In this lower map, notice that there is no grey, or blue. The coverage is much more even, and would have been improved even using the same 4 speakers in the front that the top map used. The end result is that everyone can hear, and you don’t have to cause people in the front rows pain, just to bring coverage to people in the back rows.
